Snowfall amounts are uncertain on Friday. Watch for fresh accumulations of snow forming touchy slabs in steep and wind-affected terrain.
Storm slabs have been a problem all week and will grow thicker and touchier with another 10-25 cm possible on Friday. The problem is further complicated by buried surface hoar in the trees.
Two buried surface hoar layers are in the upper meter of the snowpack; one is down 40 to 60 cm and has been recently active, the other is down 60 to 80 cm. These layers are at a time of enhanced sensitivity as they adjust to the new load.

Wind slabs likely exist on all aspects due to changing winds. Southerly slopes and terrain features have been most reactive. Loose dry sluffing may exist on steep slopes and terrain features with the recent snow.
It remains possible to trigger an avalanche on one of the surface hoar or crust layers buried 30 to 80 cm deep. These layers are most prominent around treeline elevations.
This problem is a &quot;low probability, high consequence&quot; situation. While difficult to trigger, if the layer does fail it will result in a full depth avalanche.
A weak layer of facets (sugary snow) over a crust is buried 50-100 cm deep. Triggering large avalanches on this layer remains possible in steep terrain, especially in the North Shore Mountains.
Isolated wind slabs may be reactive especially on southwesterly aspects.
Wind slabs are being found along ridgelines at treeline and above. In most areas they are resting on a thick layer of facets and could be easily triggered in unsupported terrain. Cracking was observed by forecaters in Alpine terrain on Friday.

Last weeks snow has settled into a slab. The layers of concern below vary by aspect, but are most likely to be triggered on steep southerly aspects where buried crusts exist. The slab is stubborn to trigger but large avalanches are possible.
Up to 10cm of snow from recent flurries has been redistributed by moderate NW winds onto the Southeast aspect of terrain features. This soft slab could knock a person over in steeper terrain.
The hard windslabs that dominate the alpine snowpack have been unreactive lately. It still may be possible to trigger an avalanche on steep unsupported terrain from thin areas and  the edges of these slabs.
Forecasted light snowfall and strong westerly and northwesterly winds will create touchy wind-slabs in lee terrain in the alpine.
New wind slabs have formed in the last 48hrs. They were touchy yesterday with a couple of avalanches triggered by skiers immediately below the ridgecrests on N and E asp. Be cautious of lee slopes in steep terrain.
South facing slopes are starting to heat up with daytime warming. We may start to see more cornice failures which could trigger recent or buried wind slabs. Avoid traveling in terrain exposed to cornice failures.
Moderate to strong Southwest winds beginning today in the icefields will create windslabs from the 10 - 20cm snowfall expected overnight. This  will load lee terrain features.

High to extreme S. winds have redistributed new snow onto lee slopes, creating hard and soft slabs in all wind affected areas.  At treeline, these slabs rest on a newly formed surface hoar layer (February 12). 
Moderate to strong W winds accompanied 10-30cm of new snow. This has created new windslabs in alpine and open tree-line lee features. Expect these slabs to be touchy for the next day or two.
Yesterday's frontal passage produced only sporadic snowfalls ranging from 3 to 12cm. This was redistributed by moderate to strong SW winds overnight and through most of today. Expect lee sides of terrain features to have soft slabs on them.

The presence of hard wind slabs in the alpine is likely based on the high to extreme winds that affected the area in the past few days.&nbsp; While the nature and extent of these slabs is uncertain, it is wise to watch for them in wind exposed areas.
Strong W winds accompanied 10-30cm of new snow. This has created new windslabs in alpine and open tree-line lee features. Expect these slabs to be touchy for the next day or two, especially in the alpine.
Thin pockets of windslab can be expected below Northeasterly ridge lines.  These windslabs may be triggered on steeper slopes.
The hard windslabs that dominate the alpine snowpack have bridged weakness below.  These slabs have not been reactive. It may be possible to trigger an avalanche on steep unsupported terrain from thin areas and the edges of these slabs.
Currently the wind slabs appear to be bonding well but caution should be used in steep or unsupported terrain where these are present.  If the forecast snow arrives with gusty winds on Saturday, new wind slabs will form and the hazard will rise.

Wind and little new snow dominate the alpine landscape. On certain lee features this crust is thick enough to form a wind slab,  and it may be possible to trigger an avalanche on steep unsupported terrain from thin snowpack areas.
The snowpack in the alpine and at tree line consists of multiple wind laminated layers.  How the terrain has influenced the formation and character of these layers on a given slope is the main question to keep in mind while traveling.   
A touchy surface hoar layer is down 25-40cm. There have been human triggered avalanches on this layer daily. Avalanches are increasingly possible with new snow and rising winds today adding load, and mild temperatures making the slab more cohesive.

Up to 20 cm of new snow will fall by Sunday afternoon.  Moderate W to NW winds will be building slab conditions.  These new storm slabs are sitting on smooth hard slab.  The bonding between these layers is uncertain.
There will be increasing load on the persistent slabs now buried by 15-20 cm on new snow.  There is a greater possibility that storm snow avalanches may be enough to trigger the persistent slab layer deeper in the snowpack.
A touchy surface hoar layer is down 35-55cm. Human (even tree bomb) triggered avalanches have occurred daily. Avalanches are increasingly possible with new snow and rising winds today adding load, and mild temperatures making the slab more cohesive.

New slabs forming in exposed areas with SW winds. These are spotty and small right now but will grow in size and thickness with time. Monitor the texture of the snow as you move into open areas and avoid steep terrain where these slabs are present.
Sluffing occurs easily given terrain over 40 degrees. This will diminish as the storm snow settles and is likely to occur only on  shaded slopes following the solar heating on Feb 18. Manage your sluff and your group carefully.

February 16th 20cm of snow evolved into a variable thickness windslab. It sits on a variety of surfaces and aspects. Will be found wind-pressed and thinner on windward aspects and thicker and denser on lee aspects. Overall its firm and supportive.   
Soft slabs in the high alpine are developing with the recent snow and winds. The next system late tomorrow could create further wind slabs. Expect these to be touchy within the next 24 hours.
A buried surface hoar layer, down 40-50cm, reactive to skier triggering particularly where it sits on a crust on steep south aspects. The overlying slab is stiffening and will produce larger propagation avalanches when triggered.
Moderate to strong overnight winds with new snow available to be moved by it has created wind slab at the higher elevations. Evidence of wind affect was also seen in open areas below tree line.
Moderate to strong winds from all directions in the icefields continue to scour and redistribute any snow available in the area. New windslabs may develop in unexpected locations on terrain features and ridgetops.
Moderate to strong South wind today is building slabs in lee areas (yes...again). Slab thickness and sensitivity will be variable depending on the local area.
More load over the surface hoar layer buried 40-55cm. This layer is reactive to rider triggering and remote triggering. The overlying slab will continue to produce avalanches with larger propagation and more consequence for the foreseeable future.
20cm of low density snow over the last 48hrs will produce fast sluffing is sufficiently steep terrain. With enough mass this may trigger the deeper instability.
New snow has buried previous wind slab in the alpine. Look for a stiffer slab beneath the fresh at higher elevations. Winds are forecast to pick up creating new slabs.
Expected snowfall has been reduced to light snow flurries redistributed to Easterly aspects by light to moderate Westerly winds. This just adds another thin windslab over previous hard and soft windslabs on lee sides of terrain features.
Moderate to strong S and W winds yesterday created slabs in lee areas. Slab thickness will range from 5 - 50 cm depending on how much new snow was available for transport. These slabs were unreactive today in the Lake Louise backcountry
In steep wind loaded terrain it may be possible to trigger the recent wind slabs.  These are present near ridge crests at tree line and in open areas above tree line.  Assess these spots carefully and avoid them if in doubt.

The forecasted incoming warm snowfall may bond well to the current windslab layers at the snow surface. However, if there is significant snowfall and high winds, yet another slab will develop.
Soft and hard windslabs 10-60 cm thick exist in the lees of features.  Fresh slabs will form with the incoming storm and will likely be touchy.  This may overload existing wind slabs.  A natural avalanche cycle is likely over the next few days.
With additional precipitation, warm temperatures, and moderate to strong SW winds we expect new wind slabs to form and the hazard to rise over the next couple of days.  We may also see increased cornice failures with the warm temperatures.
Rapid loading by snow and wind is overloading the snowpack. Expect widespread natural avalanche activity, with large avalanches running into valley bottoms. Avalanches may step down to deeper persistent weak layers.
A weak surface hoar layer is now down ~85cm. This layer has been triggered by humans; remotely from 40m away, and capable of wide propagations up to 150m. Rapid loading or other avalanches may trigger this layer and produce very large avalanches.
Loose wet avalanches or moist storm slabs in steep terrain are likely over the next 36hours.  Until things cool down travel in avalanche terrain is not recommended.  Things should improve quickly with the cool temperatures forecast for Sunday.
The warm, mild conditions with additional precipitation have increased the likelyhood of cornices failures and wind slab avalanches. These should start to stabilize with cooler temperatures on Sunday but should still be treated with caution.
Developing slabs overlie existing hard windslabs.  Visibility is poor, but we expect naturals to be occurring involving these layers.  In thinner snowpack areas, avalanches may scrub to ground, incorporate the weak snow and run further than expected.
The heavy snow combined with strong Southwest winds will build slabs on lee aspects.&nbsp;  These will be easy to trigger and will have enough load to perhaps step down into&nbsp; deeper weak layers in the snowpack.

The surface hoar/crust layer from February is most likely to be triggered by large triggers such as avalanches triggered in shallower layers in the snowpack and cornice falls which will result in large avalanches.
40-60cm storm slabs are poorly bonded to older surfaces. Touchy conditions at all elevations.
Strong W winds are developing wind slabs on lee aspects and will be sensitive to human triggering.
Thick soft slabs are developing with continued moderate to strong SW winds.&nbsp; Slabs are thickest and most easily triggered just below ridgelines.&nbsp; Slab avalanches can possibly trigger large, full snowpack avalanches on thin snowpack slopes.
Quantities of loose snow plaster steep cliffy terrain which is often encountered in and around ice climbs. With sufficient volume there currently to produce sizable avalanches, and more on the way, you would do well to avoid this terrain.
More than 80 cm of new snow has fallen in the Icefields area since Wednesday.  This snow is settling to form soft slab conditions on sheltered alpine and treeline slopes.
Last weeks warm and wet storm rapidly deposited 50-60cm of heavy, moist snow at treeline. This was deposited on low density snow sitting on a crust and or surface hoar and is bonding poorly. At lower elevations, rain saturated the upper snow.
It will likely take a large trigger, like a cornice fall or another avalanche to trigger the surface hoar/crust layer from February down 1-1.5m. If triggered, however, the resulting avalanche would be very large and destructive.
Storm slabs 40-60cm thick are widespread at upper elevations.  Natural activity has tapered off, but these are still sensitive to human triggering.
Another 20 cm of snow is expected overnight, adding to the 80 cm that has fallen since  Wednesday.  This new snow will come in with light north winds and rest on previous wind slabs.  
There will be 20-50 cm of unconsolidated storm snow on and above ice climbs.  This snow will be susceptible to solar, wind and human triggering forming loose snow avalanches.  Quantities will be large enough to knock climbers off their route. 
Last weeks storm rapidly deposited 50-60cm of heavy, moist snow at treeline. This was deposited on low density snow sitting on a crust and/or surface hoar and is weakly bonded. At lower elevations, rain saturated snow will have refrozen.
It will likely take a large trigger, like a cornice fall or another avalanche to trigger the surface hoar/crust layer from February down 1-1.5m. If triggered, however, the resulting avalanche would be very large and destructive.
10-20 cm of snow arrived last night with steady strong N winds. 80-100cm cm has fallen since Wednesday. This was the first real wind and many slopes appear to have a soft slab at exposed treeline and alpine locations. Reverse loading occurred.  
There remains 20-50 cm of unconsolidated storm snow on and above local ice climbs.  This snow is susceptible to solar, wind and human triggering forming loose snow avalanches of significant mass.  Enough to knock climbers or skiers off their route. 
Recent storm snow has created a touchy slab condition in all open areas. Easy triggering of slabs is expected.
Cornices are very large and unstable due to recent loading and high humidity. Natural and human triggering is likely
A buried rain crust is providing an ideal bed surface for new snow avalanches below 2000m. There's around 30cm overtop and was really reactive yesterday to rider triggering with wide propagation, running far and fast.
Moderate south winds and new snow available for transport mean that you could expect windslabs on lee terrain above treeline.
It will likely take a large trigger, like a cornice or another avalanche to trigger the surface hoar/crust layer from February down 1-1.5m. The resulting avalanche would be very large and destructive if triggered.
Storm snow accumulations since last Tuesday have been 60-80 cm or more. Both northerly and westerly winds with the storms have created storm slabs on most aspects. Touchy conditions and potential for large avalanches persist.
The cornices are very large and touchy with recent high humidity and winds. Avoid lee slopes beneath them.
In shallower areas east of the divide deep slabs have been observed failing on the lower facetted snowpack
80-100cm cm has fallen since Wednesday with initially strong N winds that shifted to moderate Westerly. Slopes below ridgelines have a soft slab developing yet remains spotty. Many gullies were reverse loaded. Wind transport is occurring in alpine. 
There remains unconsolidated storm snow on and above local ice climbs. It is is susceptible to solar, wind and human triggering forming loose snow avalanches of significant mass. Enough to knock climbers or skiers off their line.
Moderate to strong winds are building windslabs on N &amp; E aspects at treeline and above.  Tuesday might be a bit of a break but with more snow forecast for Wed windslabs will continue to be a concern. Use caution when entering wind affected terrain.
Convective snow flurries with strong winds yesterday added load to the storm slab problem above treeline. Below 2000 meters, a buried rain crust is providing an ideal bed surface for new snow avalanches at lower elevations.
Moderate south winds and new snow available for transport mean that you could expect windslabs on lee terrain above treeline.  Cornices are growing larger.
It will likely take a large trigger, like a cornice or another avalanche to trigger the surface hoar/crust layer from February 12, now down 1-1.5m. The resulting avalanche would be very large and destructive if triggered.
100cm cm has fallen since March 13. Initially strong N winds reverse loaded many slopes but now has shifted to moderate Westerly. Soft slabs are developing below ridgelines yet remains spotty in many zones. Wind transport is occurring in alpine. 
There remains allot of unconsolidated storm snow available. It is is susceptible to solar, wind and human triggering forming loose snow avalanches of significant mass. Enough to knock climbers or skiers off their line particularly when its moist..
Another 8-10cm of snow overnight has added load to last weeks storm interface.  More snow, moderate winds and warm temps today will add to this problem, especially on solar aspects where buried suncrusts are providing good failure planes.
Isolated wind slabs in the alpine and near ridge crests surprised a few skiers yesterday.  These failures could break down to deeper instabilities.  Cornices are very large and unsupported.
It will likely take a large trigger, like a cornice or another avalanche to trigger the surface hoar/crust layer from February 12, now down 1-1.5m. The resulting avalanche would be very large and destructive if triggered.
Expect new soft slabs to develop tonight and expect some reverse loading onto South aspects towards the end of the storm.&nbsp; Existing storm and wind slabs are 30-80 cm thick  Tonight's storm will add stress to the underlying weaknesses.
In shallow snowpack areas, especially East of the divide, the storm snow and wind slabs overlie a weak faceted mid-pack.&nbsp; Avalanches triggered in this region may steep down to ground.
Many large cornices loom overhead in the region.  Be mindful of  overhead hazards, especially during strong solar periods or during/after recent snowfalls and wind loading.
Deep windslabs continue to develop.  Previous winds from the north and south will be replaced by gusty moderate west winds overnight.  Because of this loading pattern, expect slab conditions on a wide variety of aspects.
Multiple convective storms and frontal systems continue to add incremental load.  The reactivity of the storm slabs is variable.  We know that solar aspects are most reactive due to buried crusts, and north aspects received most load.
Isolated wind slabs in the alpine and near ridge crests have surprised a few skiers.  These failures could break down to deeper instabilities.  Cornices are very large and unsupported.
It will likely take a large trigger, like a cornice or another avalanche to trigger the  Feb 12 and March 11 PWL's, now down 1-1.5m. The resulting avalanche would be very large and destructive if triggered.
Windslabs continue to develop with 90cm of snow since March 13. North winds with the storm reverse loaded gullies and now steady moderate west winds load N and NE aspects. Expect slab conditions on a wide variety of aspects continuing to develop.
Slabs up to 60cm thick are slowly bonding to the old surfaces. These will be more sensitive to triggering from thinner areas East of the divide, but are present everywhere. Solar aspects over all regions will have these slabs sitting over sun crust.
We have been seeing activity on the basal facets East of the divide over the recent week.  One report of a sz. 3 remote triggered in the observation peak area. 
Moderate West winds are building windslabs on N &amp; E aspects near ridge crests in open areas treeline and above. These slabs are currently thin and spotty near treeline but will be more developed above. We would expect these to settle quickly and bond
With the clear skies forecast on Sunday expect activity on solar aspects as things heat up. Most of this will likely be black body starts or minor surface sluffing but if the moisture penetrates to the well developed crusts this could produce more.
New snow is reactive to rider triggering.  Use caution in steep terrain and unsupported features.  Avalanches with large consequences may run on solar aspects. A sun crust is present down 30 cm.  Northerly aspects with wind loaded snow may be touchy.
Isolated wind slabs in the alpine and near ridge crests have surprised a few skiers. These failures could break down to deeper instabilities. Cornices are very large and unsupported.
Two weak layers are buried down 1-1.5m.  Though unlikely, a large trigger like a cornice or another avalanche may cause these weak layers to fail. 
The 90cm of snow since March 13 has generally melded with the snowpack making for a deep persistent slab. North and South winds have this present on a variety of aspects overlying weak basal facets. Cornice failures can trigger this in a big way.
Watch out for thin areas especially East of the divide where it is possible to trigger or remote trigger deep slabs on basal facets or crusts.  Be conservative with terrain choices in bigger terrain.

It may take a while for temps to warm up today, but when they do loose avalanches are possible due to strong solar. This is especially likely on steep solar aspects and around cliff and rocky outcrops. Loose avalanches may trigger deeper slabs.
The March 13 90cm of snow has melded with the snowpack making for a deep persistent slab. North and South winds make it present on a variety of aspects overlying weak basal facets. Cornice failures can trigger this in a big way.
Cornices will become increasingly prone to failure as the days get warmer. They are a hazard in themselves plus their failure is a large trigger which may initiate large avalanches potentially running full path. Watch what's overhead.

Slopes receiving direct sun become more reactive during the day with warming. This is especially likely on steep solar aspects where buried crusts exist. Solar triggered avalanches are most likely around exposed rocks and may trigger deeper slabs.
In shallow snowpack areas, particularly east of the divide, whumphing is showiing that remote triggering or triggering is still a possibility. Lower angle well supported slopes are the best terrain choice.
This continues to be the main concern with last week's avalanche activity showing deeper slabs that  were sliding full depth on weak facets and in windloaded gully features on  predominantly Northeast through to Southeast aspects.

Both loose wet and wet slab avalanches have been observed on most solar aspects up to size three. Beware of sun exposed slopes after mid-day.
With no refreeze overnight at 2100m, it will not take long for direct solar radiation to trigger avalanches on sunny aspects.
Glide cracks, gaping cracks in the snowpack, exist on many slopes and have been failing with the warm temps. They can fail unpredictably, and release the entire snowpack to the ground.
Over the past several days a spring time isothermal cycle has resulted in numerous loose wet snow avalanches up  to Class 3  on steep solar aspects in the afternoon.
  Over the past several days a spring time isothermal cycle has produced numerous wet slab avalanches up to Class 3  on solar aspects in the afternoon.
These events have been observed up to 2600m on south facing slopes. Cooler temps over the next few days will reduce the magnitude and distribution. Like loose wet avalanches these events are most likely in the afternoon when the sun is out.
With no refreeze overnight at 2000m, expect avalanche conditions where the snowpack is soft and isothermal.
Glide cracks, gaping cracks in the snowpack, exist on many slopes and have been failing with the warm temps. They can fail unpredictably, and release the entire snowpack to the ground.
Depending upon the inputs of heat from rain or sun this activity can be expected everywhere. Travelers must carefully monitor surface conditions and be clear of slopes before crusts break. Use extra caution if there is moist snow over buried crusts.
Shallow snowpack areas hold weak mid and lower layers. These areas will be more susceptible to failure with heating but have failed with large loads (such as cornices or loose avalanches) acting as the trigger.
These events have been observed up to 2600m on south facing slopes. Cool temps over the next few days will reduce the magnitude and distribution. These events are most likely in the afternoon when the sun is out or during periods of significant rain.
Loose snow avalanches can still be expected on solar aspects with day time heating. Minimal freeze overnight means crusts are not as strong and will break down sooner in the day.
Wet snow slab avalanches are still a concern with day time heating. Moist snow under the crusts means that any slide triggered has the potential to step down to ground. Large avalanches are still possible. See forecast details.
With only a gentle refreeze overnight, expect avalanche conditions when daytime heating melts the crust, and the snowpack becomes soft and isothermal. Avalanches that trigger on a shallow crust can dig deeper into the isothermal snow and get bigger.
Glide cracks, gaping cracks in the snowpack, exist on many slopes and have been failing with the warm temps. They can fail unpredictably, and release the entire snowpack to the ground and can be triggered by smaller shallow avalanches.
Cornices are large and unsupported. They are weak from the warm temperatures, and if they fail, may trigger deeper slabs.
Loose snow avalanches are still possible on solar aspects with day time heating. Monitor how well developed the crusts are in the morning and pay attention to how quickly the crusts are breaking down.

Cornices are large and unsupported. They are weak from the warm temperatures, and the warm wet new snow. If they fail, they may trigger deeper slabs.
With little overnight freeze at lower elevations, watch for loose wet avalanches below treeline on all aspects, and solar aspects at treeline and above.
  This will be more prevalent at lower elevations due to lack of freeze, but if the sun pops out Saturday, there is the potential for deeper releases as the day warms up.  Cornices will act as an ideal trigger.
Additional snow coming overnight may provide the load to start a slide on this layer.  Slab bonding is expected to be touchy on the current sun and temperature crusts.  Expect to see this type of activity in steep rock gullies.
Natural avalanches are possible with the current spring conditions. Avalanches that trigger on a shallow crust can dig deeper into the isothermal snow and get bigger.
Up to 15 cm of new snow at treeline and above could be rider triggered.&nbsp; Watch for this snow to have formed a slab of denser snow.&nbsp; Especially on leeward features in open terrain.
Overnight snow accumulations may provide enough of a load to initiate slides on the temperature crust. Incoming North winds may load South aspects where this crust is well formed. Assess bonding of the new snow before committing.
Below treeline expect near isothermal conditions with little freeze.  At treeline and above, natural loose wet avalanches will occur if the sun comes out and the day heats up.
The highest likelihood for deep wet slabs is from daytime warming on solar aspects,  especially from thin areas where slabs overly facets or depth hoar. 
Natural avalanches are possible with the current spring conditions. Avalanches that trigger on a shallow crust can dig deeper into the isothermal snow and get bigger. Use caution in terrain with loose unconsolidated snow.
This is less of a concern with cooler temperatures but increases its probability if the sun comes out. New snow rests on a buried smooth temperature crust particularly on South aspects. The surface snow can quickly become wet and active with heat.
Below treeline expect near isothermal conditions with little freeze. At treeline and above, natural loose wet avalanches will occur if the sun comes out and the day heats up.
The highest likelihood for deep wet slabs is from daytime warming on solar aspects, or from periods of rain, especially from thin areas where slabs overly facets or depth hoar.
Glide cracks, gaping cracks in the snowpack, exist on many slopes and have been failing with the warm temps. They can fail unpredictably and release the entire snowpack to the ground.
New snow (15cm) rests on a buried smooth temperature crust particularly on South aspects. The surface snow can quickly become wet and active with heat from the sun.
This layer will likely be most reactive to human triggering where it sits on a buried crust (solar aspects) or in areas that have received wind effect. We may see some natural activity on this layer when the sun comes out and destabilizes it.
Glide cracks, gaping cracks in the snowpack, exist on many slopes and have been failing with the warm temps. They can fail unpredictably and release the entire snowpack to the ground.
The forecasted precipitation, winds, and increased temps will create new storm and windslabs that will be most reactive during the storm. Natural activity will decrease once the system passes, but the newly formed slabs will take a few days to settle
Up to 25 cm of storm snow accompanied by strong SW winds will build slab conditions on the smooth sliding surface formed by previous temperature crusts on lee treeline and alpine slopes.
10-15 mm of rain on Wednesday will destabilize the melt freeze crust currently covering the isothermal snow below.&nbsp; Expect loose wet slides on steeper slopes and in gulley features.
Glide cracks, gaping cracks in the snowpack, exist on many slopes and have been failing with the warm temps. They can fail unpredictably and release the entire snowpack to the ground.
Weak shallow areas are most sensitive.  The character is stubborn to trigger, but seems to result in wide propagations (big avalanches), and is susceptible to remote triggering. 
10 cm of storm snow accompanied by strong SW winds have built stiff slab conditions on the smooth sliding surface formed by previous temperature crusts on lee treeline and alpine slopes.
The forecasted precipitation, winds, and increased temps will create new storm and windslabs that will be most reactive during the storm. Natural activity will decrease once the system passes, but the newly formed slabs will take a few days to settle
40 cm of heavy moist storm snow overnight with steady south winds has created slabs at and above treeline.  This layer will be touchy today, especially as temperatures warm up.
Glide cracks, gaping cracks in the snowpack, exist on many slopes and have been failing with warm temps. They can fail unpredictably and release the entire snowpack to the ground.  The  overnight storm snow may provide a trigger for deep releases
Weak shallow areas are most sensitive.  The character is stubborn to trigger, but seems to result in wide propagations (big avalanches), and is susceptible to remote triggering.
Isolated soft slabs in the immediate lee of alpine features were reported in the Lake Louise area, as well as up 93N. 10-15cm thick slabs were touchy and propagating upwards of 20m from skiers/riders.
Recent winds have formed new windslabs on lee aspects below ridgecrests above treeline.  These slabs are roughly 10-15cm thick, and where they are sitting on previous crusts may be reactive to skier traffic.
Recent snowfall came in warm and stuck to steep rock and ice.  This terrain will shed this snow with daytime heating.
New, storm snow can be skier triggered.  Up to 70 cm of storm snow has created a slab on top of a crust.  Below treeline this snow is moist.  Treeline and above, south winds have loaded lee features.
Weak shallow areas are most sensitive. The character is stubborn to trigger, but seems to result in wide propagations (big avalanches), and is susceptible to remote triggering.
The primary concern is where new storm slabs are sitting on previous crusts,in which case they may be triggered by light loads. Existing windslabs on lee aspects will also become more sensitive to triggering with the increased load from the new snow.
Watch for isolated soft slabs in the lee of alpine features.  These were obvious to see and avoid today, but will be blanketed by new snow tonight.  Moderate to strong southerly wind tonight and north wind tomorrow add to the current slab condition.
An additional 10cm of new snow on top of the previous 35cm. This 45cm storm slab sits on a thick crust that could provide a good bed surface for an avalanche where the slab has not yet had a chance to bond to it.
Expect sluffing in steep terrain today and watch for terrain traps where a small avalanche can result in big consequences.
Weak shallow areas are most sensitive. The character is stubborn to trigger, but seems to result in wide propagations (big avalanches), and is susceptible to remote triggering.
With mild spring temperatures and variable winds, new snow quickly settles into a slab. With sun and temperature crusts as a firm bed surface the bond of this new snow should be examined carefully before committing to steep or unsupported terrain 
New snow from recent and incoming storms will fail easily in steep terrain with skier traffic and naturally from extreme terrain. With underlying crusts these events may travel  a long distance and gain mass. Manage your group carefully.
Winds have formed windslabs on lee aspects below ridgecrests above treeline. These slabs are roughly 10-15cm thick sitting on previous crusts. It is possible to initiate from skier traffic where its bonded poorly to the underlying crust.
Watch for isolated soft slabs in the lee of alpine features.? These were obvious to see and avoid today, but will be blanketed by new snow tonight.?
Another 10cm overnight at tree line and above with reverse wind loading patterns. Storm snow instabilities and wind slab will exist at higher elevations before things have a chance to settle out.
Loose snow sluffs can gain mass in steeper terrain catching a rider off guard today. Be mindful of terrain traps (e.g. gullies, cliffs) where small avalanches can be more serious.
Infrequent large avalanches have occurred on deeper instabilities. Shallow, rocky areas where the snowpack is thin and weak are most likely where they will be triggered.
Winds continue forming windslabs on lee aspects below ridgecrests. These slabs sit on previous crusts. Suspect it remains possible for a skier to initiate this slab where it bonds poorly to the underlying crust. N winds reverse loading pockets.
Watch for isolated soft slabs in the lee of alpine features. These slabs are now hidden, since they have been buried by last nights snow fall (&lt;10cm)
40-50cm of storm snow is being transported by variable winds. N'ly winds have reverse loaded solar aspects and may bond poorly where buried sun crusts exist. The wind is also building large, unsupported cornices.

Infrequent large avalanches have occurred on deeper instabilities. Shallow, rocky areas where the snowpack is thin and weak are most likely where they will be triggered.
Windslabs can be found on lee aspects in exposed terrain around ridgecrests. Where these slabs sit on previous crusts, the likelihood of a skier triggered avalanche increases.
Watch for isolated soft slabs in the lee of alpine features. These slabs may be hidden by recent light snowfall.
More snow is expected today increasing the avalanche hazard. A new surface hoar layer is down around 20cm under this new snow. It has widespread distribution and will be easily triggered by riders under this new load.
A surface hoar layer buried down 50-110cm at the higher elevations is within the range of rider triggering.
Hard wind slabs pressed into lee and cross loaded features at tree line and above.
4cm thick rain crust found below tree line and up to 2700ms. No new avalanches have been observed on this layer.
Lee alpine slopes have lingering wind slabs that may be reactive to skier traffic. Probe for evidence of wind slabs over weak facets and use caution in this type of terrain. Areas that receive significant snow will also have new wind slabs forming.

The surface hoar buried earlier this month is slowly decomposing, but could be reawakened by surface slabs overloading it.
Higher elevation, lee slopes and gully feature areas may have developed wind slabs during the storm that came in from the north. Evaluate the snowpack for stability prior to stepping into it. Limited field observations thus far this season.
The October melt freeze crust and basal depth hoar are a a concern and avalanches may step down to basal layers. This is primarily a concern on steeper features especially if they are windloaded.
Reverse loading has created new slabs on southerly aspects. Although less reactive with the colder temperatures, watch out for lingering wind slabs on N-NE aspects.

These slabs will be lurking in the areas that look appealing with the thin coverage: open areas on the lee of ridgelines and along the lee portions of lower elevation fan and gully features.
Strong to extreme gusting winds from the South through to the West will be developing additional windslabs on lee aspects at treeline and on lee terrain features in the alpine.
A small avalanche on a lee aspect may step down to this layer and could go to ground on the facets.
New snow and strong W winds are creating wind slabs in lee areas. Not much activity has been observed yet however the hazard is slowly increasing and these wind slabs have the potential to step down into the basal facets to create larger avalanches.

As the storm continues to dump snow, with strong winds and warm temps, the storm slab is becoming deeper and more cohesive. There are reactive layers within and at the base of the slab that are likely to be triggered by skiers.
The storm has rapidly loaded slopes and may overwhelm persistent weak layers buried deeper in the snowpack. Very large avalanches will result if these layers are triggered.
Strong to extreme SW'ly winds will be forming windslabs and cornices at treeline and above.
A week of windy weather has stiffened the skiable terrain. Triggering may still be possible. Watch for these conditions in appealing looking open areas.
Associated with mid pack crusts we see a layer of sugary crystals underlying stiffer upper layers. Use more caution in thin areas as triggering&nbsp; may be more likely.
Continued snowfall and strong winds will create deep windslabs in most areas above treeline. Stay off steep, loaded slopes and climbers should avoid deep, avalanche prone gullies where spindrift is forming windslabs.
The base of the snowpack is weak and should not be trusted this early in the season. Avoid large open slopes in alpine and treeline areas.
Wind slabs will continue to develop with the new snow and gusting winds. The turbulent winds seem to constantly change direction and gusts are pushing into extreme wind speeds. Expect to find wind slabs in unusual terrain features.
Even a small wind slab avalanche has the potential to step down to this layer and to release the facets to ground.
55-60cm of storm snow in the past week with mild temperatures have created ideal slab conditions.
We have had strong winds during yesterdays storm leaving us with wind slabs at higher elevations.
Buried surface hoar down between 60-80cm with a recent significant snow load should remain a concern for rider triggering.
Winds gusting from all directions are redistributing the snow into the sheltered terrain features. Any slope is steep enough to slide and has enough snow to ski, should be evaluated for windslabs.
Any slope or terrain feature that was sheltered enough to hold snow in October could have this raincrust on it. Facets developing above and below this layer may cause even a small avalanche to step down to ground.
20-40cm storm snow over the past few days has been moved by strong westerly winds creating fresh, touchy slabs on steep lee features.
Many of the recent avalanches have been stepping down or failing at the base of the snowpack on the early season weak base..

Strong winds throughout the storm, with lots of snow available for transport, have loaded lee slopes and formed wind slabs at treeline and above. Wind slabs may be triggerable; watch for signs like cracking or hollow sounding snow.
The recent snow has tightened up into a slab. It sits on various weak crystals, like facets or surface hoar, that may be triggered by skiers. If triggered, avalanches may step down to deeper surface hoar layers resulting in very large avalanches.
Increased winds from the south and west have contributed to a new load on alpine lees.&nbsp;

Watch for new wind slabs forming in open areas above tree line as well as old wind slabs which may be hidden beneath the recent snow. Check leeward or cross loaded areas carefully for the presence of wind slabs before entering these types of lines.
Snow load has been steadily increasing over the last few days. With rising temperatures, wind and more snow on the way, riders should expect to see snow slabbing up and becoming more reactive as the day progresses.
2 weak layers exist in the snowpack, these are down between 70 and 110cm. They could become reactive with this additional snow load having very large consequences if triggered.
The Oct 27 raincrust has a sporadic distribution. An avalanche on this layer could still step down to ground and have severe consequences. We have observed a few avalanches on this layer recently.
Recent turbulent winds have redistributed snow into sheltered terrain features. Anything that is steep enough to slide and has sufficient snow to ski on should be evaluated. Recent snow likely is hiding this problem.
Overall the snowpack is very weak, and full depth avalanches are likely to be human triggered in specific areas. Stick to low angled terrain without any overhead hazard, and try to avoid all avalanche starting zones under these conditions
Wind slabs may exist in some areas of wind loading at higher elevations. While these avalanches may be initially small, once started they have the potential to trigger a larger, deep slab.
Winds have picked up overnight with lots of snow available for transport. Use extra caution on lee and cross loaded terrain particularly near ridge crests
Storm snow amounts keep accumulating with another 12cm overnight. It will need some time for storm layers to bond.
2 weak layers exist in the snowpack, these are getting deeper as snow amounts increase. They are down between 70 and 120cm and will have devastating consequences if triggered.
Thin and soft slabs formed with recent snow and warm temperatures can be found almost everywhere. With time, the forecast West Winds will likely redistribute this snow to form wind slabs near ridgelines and in gully features.
Weak snow associated with crusts formed in Mid and early November can be found down about 70cm. This seems to be less significant on Southerly aspects. Triggering planar slopes from thin areas remains a possibility to consider.

Strong SW winds are expected today. They will intensify the rate of loading onto lee slopes and form new windslabs. The new snow will also bury pockets of windslab that have been reactive to skiers in lee and crossloaded terrain.
40cm of recent storm snow is settling. Within this slab are layers of large, weak snowflakes that may be triggered by skiers/riders or by rapid loading during the storm. If triggered, this slab may step down to deeper instabilities.
Persistent weak layers down ~80cm (facets), and down ~115cm (surface hoar) continue to be reactive in specific locations. Although these interfaces are becoming less likely to trigger it is possible, or smaller avalanches may step down to this layer.
The crust and or depth hoar at the base of the snowpack means that any avalanche that begins will likely step down and involve the entire snowpack.
Wind transport has created a mix of hard and soft slabs on all lee and cross loaded slopes . Terrain choices are tricky because the only places that have enough snow are wind loaded. Use shallow slope angles to minimize risk.
Currently there is a variably distributed persistent slab in a generally shallow snowpack. Although stubborn, if this slab is triggered it will result in a full depth avalanche running on weak layers at or near the bottom of the snowpack.
Steady Southwest winds have created pockets of windslab on lee features above treeline. Recent natural activity has been observed in crossloaded gully features in the alpine.
Conditions are ideal for slab formation; strong SW winds, with mild temperatures are forecast. The strong winds will intensify the rate of loading onto lee slopes, and form new windslabs on lee slopes.&nbsp;
Alpine temps rose overnight to 0'C at 1900m, before dropping below freezing again. Recent storm snow will have become more cohesive. There are a few weak layers within this slab. Tests indicate that they may be triggered by light loads, like you.

Recent moderate/strong SW winds have loaded lee features at treeline and in the alpine. Stay off wind loaded areas until the slope has had a chance to stabilize.
Weak layers are buried down 80 to 100 cm. In a shallow snowpack where the weak layer is well-preserved, a skier could fail these layers.
Expect this layer to persist for a long time. Best to make conservative choices as triggering this layer could have severe consequences. Likely trigger locations are shallow locations but everything is shallow right now.
New snow overnight and winds will continue wind slab development. Fresh snow may be hiding this condition.
This problem is classic. Hard to trigger, but when you hit the sweet spot (which you cannot see), full depth avalanches are likely. Don't ski aggressive terrain, the consequences are high so mange your exposure to starting zones very carefully.
10-20 cm of light new snow has fallen in the last 48-hours, and has been blown into thin windslabs in some areas. Check for windslabs and avoid freshly loaded areas. Ice climbers should watch out in steep cliffy terrain.

The recent storm snow has instabilities within it that will need a few days to heal.
The 2 buried weak layers down 70 to 110cm are still producing results in our snowpack tests. Caution around shallow snow pack areas where triggering these layers is most likely.
Expect this layer to persist for a long time. Due to its unpredictable nature, use conservative choices as triggering this layer could have severe consequences. Shallow locations are likely trigger spots. Generally, everything is shallow right now.
New snow over the weekend and winds will add to the wind slab development and hide it in some cases. Check for freshly loaded spots where a pocket of this instability would exist. Iceclimbers be cautious of crossloaded gullies and terrain traps.
Local avalanche forecasters are concerned about this problem, and are calling it a &quot;lurking beast&quot;. Deep slabs that are hard to trigger, but the consequences getting caught are dire. Manage your risk by minimizing exposure to avalanche start zones.
This problem is mostly small surface slabs formed from recent new snow and strong winds. Above 2400 meters one should expect windslabs in most areas. Locate these windslabs by monitoring the density of the surface snow as you travel through terrain.
Winds have been steady in the moderate to strong range for the past 24hrs.
Mild temperatures today will make slab formation more likely.
2 buried weak layers down 70 to 110cm remain a concern for riders. Consequences would be large if triggered which is more likely from shallow snowpack areas.
Triggering this layer could have severe consequences. Shallow locations are likely trigger spots and, everywhere should be considered shallow right now.
Check for freshly loaded spots where a pocket of this instability would exist. Ice climbers, be cautious of cross-loaded gullies and terrain traps
Up to 35 cm settled storm snow in past three days found at tree line west of the divide and 10-20 cm east of the divide. Continued westerly winds have created hard and soft wind slabs at treeline and alpine elevations.
The midpack and basal pack is mostly weak facets and depth hoar. The potential for a full depth avalanche continues to exist if the sweet spot is triggered.
Winds associated with this recent snowfall have been strong enough to create wind slabs at higher elevations and in exposed areas below tree line.
Another 25cm of new snow overnight. Snow loading has been steady for the past 5 days with instabilities in the upper snowpack.
The presence of buried surface hoar remains a concern for backcountry riders. The potential for a large avalanche on this layer still exists.
West winds have built wind slabs in lee areas and cross loaded terrain such as gully features. Triggering may be possible on steeper or unsupported features.
This layer of weak sugary snow is found in many areas&nbsp; about 30 to 40cm from the ground. Triggering&nbsp; of this&nbsp; layer is more of a concern in shallower snowpack areas.
Several avalanches have been observed on this layer. Wind loaded slopes should be carefully evaluated.
&nbsp; Avalanches on this layer have potential to step down to weaker basal layers resulting in large slides.&nbsp;
Recent snow &amp; wind loading has resulted in a few slides size 2-3 failing to ground. Avalanche professionals in the Louise area went for a ride today after placing 7 explosives in a feature then ski cutting it &amp; hitting the hidden mine to trigger it.
New and old wind slabs exist in the region.&nbsp; Once triggered these slabs are likely to step down the basal weak layer incorporating the entire snowpack in the slide.
An issue on the West side of the Divide where 40-70 cm has fallen in the past few days.&nbsp; Both slab and loose avalanches have been observed today and are expected to continue with forecasted wind.
Another 10cm in the last 24 hours continues to incrementally load the snowpack. Moderate winds have created soft slabs in exposed areas.
Winds associated with the recent snowfall have been strong enough to create slabs in the alpine and exposed areas at and below tree-line. These slabs are concealed by the incremental snowfall of the last few days.
The presence of a deep surface-hoar weakness remains a concern for backcountry travelers. It will likely take a large load to trigger it, like a cornice or someone who ate too many perogies over Christmas.
This is the predominant layer in the snowpack, and full depth avalanches to ground have been observed daily over the past week. This will increase in frequency with the new snow.
Watch for areas of wind loading. If a wind slab is triggered it may step down to deeper layers.
This is mainly a problem at treeline and below, West of the divide where 40-70cm of snow has fallen over the last six days. There has been less wind in these areas, and high humidity has promoted slab development over the facets.
  A shallow spot in the snowpack could trigger a windslab which in turn would step down and release the entire snowpack.
Lee aspects have an upper snowpack consisting of several hard windslabs which could release and affect the layers below it.
Storm slabs will become an issue at the peak of the incoming system. Strong winds and warm temp's accompanying the new snow will develop slabs quickly in exposed lee features at all elevations.
Wind slabs are still reactive to rider triggering in the upper snowpack. Large planar or unsupported slopes should be treated with respect.
A deep persistent weakness lingers, down roughly 120cm. It will take a large trigger to initiate this layer, but if it starts to move, propagation would likely be wide and deep, creating a larger avalanche.
Triggering this layer from a shallow area is possible and would have high consequences in terrain features of any size.
Multiple wind slab layers at the top of the snowpack can be triggered and may step down to the deeper instability at the bottom of the snow pack.
Hard surface slabs are found near ridge crests and in gully features. These are highly variable at the moment with suspect pockets in steep and unsupported terrain.
Weak faceted or sugary snow can be found almost everywhere 30 to 40 cm above the ground. Triggering in thin snowpack areas remains a concern. Some natural avalanche activity should be expected if snowfall amounts are significant Friday.
The incoming snow will cover a variety of firm surfaces including the windslabs described above, wind affected surfaces, and sun crusts on S aspects. West winds and mild temperatures are likely to encourage slab formation in specific areas.
This is the main layer of concern. Full depth avalanches to ground have occurred daily over the past week. This layer will be stressed further by tonight's storm increasing it's sensitivity to natural and human triggering.
Watch for areas of wind loading or open slopes with wind effect. If a wind slab is triggered it may step down to deeper layers.
This is mainly a problem in the main ranges where the 40-50 cm of storm snow is not yet bonded to the old snow. Shooting cracks and whumphing was observed at treeline west of the Divide as skiers attempted to access more open terrain.
Storm slabs have formed at all elevations, likely up to a metre thick in alpine and tree-line lee areas. It will take a bit of time for these to settle into the snowpack.
Older wind slabs buried on various weak layers linger below all the new snow. These slabs have the potential to fail with the new, heavy load.
The heavy trigger may have arrived with this latest dump. Large avalanches are occurring, and may be stepping-down to this deeper layer.
This is the main layer of concern. Full depth avalanches on the basal depth hoar and crust have been occurring every day in the last week. The new snow has added stress to this layer, and will be easiest to trigger this layer in thin snowpack areas.
Watch for areas of wind loading or open areas with wind effect. If a wind slab is triggered it may step down to the weak basal layers. The new snow will be hiding these wind slabs in many areas.
The 20-30 cm of new snow can be expected to slough with any wind that occurs over the next 24 hours. Ice climbers should especially watch for sloughing in steep gully features and terrain traps.
Triggering this layer from a shallow area is possible and would have high consequences in terrain features of any size.
Multiple wind slab layers at the top of the snowpack can be triggered and may step down to the deeper instability at the bottom of the snow pack.
Up to 30cm of new storm snow is not yet bonded to the old snowpack.
40 to 60 cm of storm snow has formed slabs. These deposits will be deeper in areas with wind loading. Natural avalanches are still possible, assess terrain continually while you travel.
Older wind slabs are buried on various weak layers below new storm snow. Use your pole to feel for this firm, wind-deposited snow in exposed areas. These slabs have the potential to fail with the new, heavy load.
Triggering this layer from a shallow area is possible and would have high consequences in terrain features of any size.
Wind slab layers at the top of the snowpack can be triggered and may step down to the deeper instability at the bottom of the snow pack.
The mid pack is strengthening in thicker snow pack areas but this means the potential for larger propagations on the weak basal layers is a real concern.  Stick to moderate angled well supported slopes and minimize exposure to large avalanche paths.
New wind slabs are forming with lots of new snow available for transport.  If triggered these have the potential to step down to deeper facet layers and create large avalanches.  Probe for new or old wind slabs and avoid steep lee loaded terrain.

Storm snow and wind have overloaded the weak basal layers in several places and caused numerous large natural avalanches in the alpine. Cornice fall, smaller slides, and skiers in shallow areas all have the ability to trigger deeper instabilities.
Recent storm snow and strong winds in the alpine are forming new windslabs at upper elevations.
There is lots of new snow plastered to steep rock and ice terrain. With the expected warming trend (and solar effect) over the next week, expect this terrain to shed this snow.
Large, deep slabs are occurring naturally and from human triggers. The recent snow has tipped the scale and all avalanche terrain should is suspect. Numerous avalanches have been triggered from long distances away. Avoid avalanche terrain!
Windslabs have formed over the last 48-hours, and this trend will continue over the next few days as strong north winds are forecast at higher elevations. Small avalanches are likely to step down and release larger avalanches on the deep layers.
Temperatures are warmer up high today due to an inversion. Caution on and under steep solar aspects when the sun is shining on them. Loose avalanches will most likely originate from cliffs.
Wind slabs at ridge crests and in the alpine from the strong winds during the last storm may still catch a rider off guard.
Storm snow instabilities still exist in the recent storm snow. Although it appears to be bonding well, another day or two of settlement and observations is needed before it is no longer considered to be a problem.

The weak snowpack continues to dominate the entire region, and avalanches can be easily triggered in shallow areas at treeline and above. Keep your distance from avalanche starting zones, and work the terrain very carefully to manage your exposure.
Recent winds have created thin windslabs on steep, windloaded terrain features. Approach all windloaded terrain with respect, stop at the top and evaluate before you choose your route through.
Snowpack tests yesterday showed instabilities in the upper 60cm in the moderate range.
Strong West winds made quick work of the 40 cm of snow that fell before the weekend. Thin, spotty wind slabs found behind exposed features well below treeline can be easily triggered by skiers. Expect these slabs to be more significant TL and above.
This weak layer of snow persists 30 to 40 cm above the ground. Triggering a wind slab could produce the large load necessary to wake this layer up. Use caution in thin areas particularly with steep, planar, or unsupported slopes.

&nbsp; A generally weak and faceted snowpack dominates the forecast area. The potential for full depth avalanches exist.
Significant  fresh wind slabs exist in exposed terrain. The potential for a small wind slab avalanches stepping down into the facets below is a concern right now.
The 40-50cm of snow from last week's storm continues to settle. Resistant planar results were seen in snow tests yesterday on this layer.
Many avalanche paths have already slid in the 2,400 m - 2,800 m range. Slopes that have not failed are expected to fail with the increased snow loading and winds this weekend.
The upper snowpack is a stratified layer of multiple windslabs. Recent field tests have produced failures with moderate shear strength. Currently this condition is less prevalent at treeline. Forecasted snowfall and wind will increase this concern.
The weak base is the real danger. Moderately angled slopes with thicker snowpack are the best choices for not triggering this layer.
Fresh storm slabs can be triggered and will have the potential to step down to the weak base.
The storm slab is bonding well, as indicated in snowpack tests throughout the park. Use caution when entering wind-affected areas in the alpine and at tree-line.
The weak base is the major problem layer in the snowpack. Avalanches will almost certainly involve the entire snowpack.
Recent windslabs near ridge crests may be triggered. Avalanches will likely step down to the weak base.

The upper snowpack is a stratified layer of multiple windslabs. Recent field tests have produced failures with moderate shear strength. Currently this condition is less prevalent at treeline. Forecasted snowfall and wind will increase this concern.
Strong winds with a continuation of new snow will keep building windslabs in open areas. These can be found well below treeline.
This weak layer of snow persists 30 to 40 cm above the ground. Triggering a wind slab could produce the large load necessary to wake this layer up. Use caution in thin areas particularly with steep, planar, or unsupported slopes.
A new storm slab is developing. The new snow is still loose and unconsolidated, but with mild temps and continued loading by new snow it will become more of a concern. Heads up if the snow starts to feel slabby. Watch for sluffing on steep slopes. 
The persistent weak layers are now fairly deep in the snowpack. They will&nbsp; likely need a sizeable trigger, like an avalanche or a large chunk of cornice falling. They may be triggered from thin snowpack areas by a lighter trigger, like you.
New snow will likely overload deep weaknesses in the snowpack causing increased avalanche activity.
Alpine and tree line winds had added a stiff wind slab to the weak snowpack. If this layer triggers it will likely step down to the basal weakness mentioned above.
The forecast snow this weekend may be enough to overload the basal facets in many areas with potential for large slab avalanches. Stick to well supported, planar terrain below 30 degrees and minimize exposure to start zones.
Wind slabs will build quickly over the weekend. Expect sluffing in steep alpine terrain and avoid steep lee loaded features. Triggering a wind slab may also cause it to step down to the basal facets resulting in a larger than expected avalanche.
60 to 70cm of storm snow has fallen over the past 3 days with strong southerly winds. Heavy density snowfall is rapidly loading a previous layer of low density snow causing storm slab formation.
The current rapid loading event could reawaken the deep slab that has been sleeping for the past week.
The storm has overloaded the weak and facetted snowpack, and large natural avalanches are being observed. Active deep persistent slab conditions like this are dangerous; avoid avalanche terrain for the next few days - time for good snow in the trees.
20-40 cm of storm snow has fallen across the forecast region, creating unstable snow in the surface layers from both new snow and wind. Expect deep windslabs in leeward areas due to extensive wind loading.
&gt;35 cm of storm snow has fallen in the past 24 hrs and has been redistributed by moderate SW winds. This new snow is overloading the weak snowpack below resulting in large deep avalanches.
In many areas, the basal facet weakness has been avalanched away, where this has not happened, there is a lot of snow sitting on top of this unstable weakness.
These winds slabs have now been buried by the new snow so will be hard to locate.&nbsp;
Over 75 cm of heavy storm snow has fallen with moderate/strong southerly winds. This new snow is causing natural avalanches and is very touchy to human-triggering.
The current avalanche cycle is overloading the entire snowpack and many deep avalanches have been observed sliding on the ground. Fracture lines in some areas greater than 150cm deep. The situation is very touchy; avoid all avalanche terrain.
45 cm storm snow and extreme winds have created deep storm slabs that can easily be triggered by humans. Extreme winds on Monday night will only add to this problem.. Avoid all avalanche terrain until this cycle subsides.
55cm of storm snow has fallen in the past 48hrs and is being redistributed by moderate to strong SW winds significantly overloading the snowpack. Lee features will be creating dangerous conditions overhead and underfoot.
Forecasted new snow will continue to overload an already stressed snowpack.
Triggering any of the above problems have potential to initiate this layer and create large full path avalanches.
New overnight snow is exceptionally heavy with the mild temperatures we have. This snow is sitting over much lighter snow from earlier this week and the result is ideal slab conditions and weak layers for it to slide on.
Winds in the past 24hrs have been strong to extreme with gusts to 130km/h on Mt Macdonald.
The November persistent weak layer is more likely to be triggered in times of heavy loading such as these with storm snow avalanches stepping down to this layer.
The possibility of natural and skier triggered avalanches remains high. Stay out of avalanche terrain until things settle down. Look for protected skiing in the trees on moderate angled slopes with no exposure to alpine and tree line start zones.
The storm slab is 40-50cm thick in many places and if triggered, it is likely to step down into the basal facets resulting in very large avalanches. Avoid all avalanche terrain until this cycle subsides.
This layer is proving very susceptible to human triggering as evidenced by the two remotely triggered slides today. Extensive whumphing and cracking experienced particularly at treeline elevations.
70cm of storm snow has fallen in the past 72hrs and has been redistributed by moderate to strong SW winds onto sheltered slopes in the alpine and treeline.
A failure in this layer is likely to trigger the weak basal facet layer below.
Yesterdays blizzard deposited 35cm of heavy snow that is sitting over snow that is much lighter, including a buried surface hoar layer. This combination makes it more reactive to rider triggering until it has a chance to settle out.
The winds associated with the storm yesterday were strong throughout the park at all elevations. Slopes near ridge crests should be treated with caution.  Wind slabs may exists in open areas below tree line above where there's a melt freeze crust.
The November surface hoar layer can still be triggered by large triggers such as avalanches or cornice fall. There have been reports of backcountry operations seeing avalanches failing on this layer in the region.
Open terrain near ridge crests are likely spots to find recent wind slabs. Use your poles and probe to help detect signs of instability.
More likely areas where the slab could be triggered are in&nbsp; steep unsupported terrain.
In shallow snowpack areas there is a possibility that the deeper instabilities could be triggered. Our growing snowpack and milder temperatures are helping to reduce the chance that this layer could be triggered in most areas.

Expect to see less natural activity concerning this layer, however, it is still ripe for human triggering. If triggered, expect large and destructive avalanches with fracture lines up to 200cm deep.
Unlike the deep persistent slab problem, the storm slabs will eventually start to bond to underlying surfaces over the coming days.
Warmer temperatures will contribute to overloading the weak basal facets leading to full depth avalanches in the valley bottoms. Be cautious of steep slopes along terrain traps such as creeks.
As the warmer temperatures stiffen up the snow surface, even a small avalanche could step down to the basal facet layer resulting in a full depth avalanche.
Strong winds have formed windslabs in open areas at all elevations. In many areas they have formed over lower density snow, which may be triggerable.
Over a meter of new snow, combined with high winds and rising temps, have created a storm slab. It is sitting over snow that is much lighter, including a buried surface hoar layer. This slab will need some time to settle and bond.
The recent avalanche cycle showed the reactivity of the snowpack to rapid loading and its capability to produce large avalanches. Until the snowpack adjusts to the new load these layers may be reactive. Be cautious in areas that have not avalanched.
Depending on elevation, this layer is either bridged by a hard mid-pack at higher elevations and likely to be triggered from a shallow area. At the lower elevations there is minimal support in the snowpack and is easier to trigger.
Triggering this layer could potentially initiate deeper instabilities. 
Full depth avalanches have been seen daily on this layer. We expect another natural avalanche cycle on this layer on sunny aspects with the forecasted warm temperatures and sun.
Any avalanche triggered as a windslab is almost certain to step down to the basal facets and trigger a much larger avalanche.
Over a meter of new snow is about to get hit by lots of solar and above freezing temps right up to mountain top. Natural avalanches are expected from steep, solar aspects. In addition, the storm slab will likely be more reactive on sun exposed slopes
Strong winds have formed windslabs in open areas at all elevations. In many areas they formed over lower density snow, which may be triggerable. Be especially cautious in places where even small avalanches can have high consequences, ie over cliffs.
The recent avalanche cycle showed the reactivity of the snowpack to rapid loading and its capability to produce large avalanches. Likely triggers are cornices failing and other avalanches stepping down. Be cautious in areas that have not avalanched.

Any windslabs triggered will likely step down to the basal facets and trigger a much larger avalanche.
Basal weakness means that the potential for full depth avalanches still exists.&nbsp; Smaller avalanches have the potential to trigger deeper instabilities.
Wind slabs are still touchy at upper elevations.&nbsp; Extensive scouring and cross loading was apparent today during helicopter control efforts on upper targets in the alpine.&nbsp;
Natural avalanches are expected from solar aspects if the high, thin cloud breaks up. Over a metre of new snow may have trouble adjusting to intense sunshine and high freezing levels over the next 48hrs.
Strong winds formed windslabs at all elevations and on all aspects. These windslabs sit on a low density layer and can be triggered by light loads. Be cautious in areas where even a small avalanche can have large consequences, ie over cliffs.
Be cautious in areas that have not avalanched. The recent avalanche cycle showed the reactivity of the snowpack to rapid loading and its capability to produce very large avalanches. Cornices could be the large trigger to break down to the deep layers
Strong west winds have created windslabs on lee slopes below ridgelines. These slabs can be found well down from the ridgetop and into open areas due to the intensity of the wind. Warm temperatures will increase the likelihood of triggering.
Snowpack depth is highly variable. It might be hard to spot the shallow areas where triggering this deeply buried weak snow is more likely. Large loads such as falling cornices or surface avalanches also have the potential to wake up these slabs
Warm temperatures and sun will weaken the large cornices that developed from the snow and wind from last week. These could be the large load required to trigger the deeper instabilities in the snowpack and create large avalanches.
Watch for daytime warming and areas receiving large amounts of sun. avalanches may run full path and affect valley bottoms and trails crossing avalanche runouts.
The basal facet layer is of great concern as it is&nbsp; the most significant weakness in this year's snowpack.  Use extra caution in areas that have not previously avalanched, especially on open treeline slopes.
Windslabs have been triggered on this interface buried in the snowpack as well as deeper on the basal facet layer.
Strong winds formed wind slabs is exposed terrain at all aspects.  These wind slabs sit on a low density layer.  This layer could possibly be human triggered.  Be cautious in areas where even a small avalanche can have large consequences.
A weak layer buried down over 2 m will take a large trigger to fail. Limit your exposure to cornices.  A cornice fall to could be just the right trigger to fail this weak layer.
Frequency of full depth avalanches on the basal depth hoar/crust is starting to slow down.  Any slope that hasn't avalanched should be treated with caution, as it will be very high consequence if you trigger this layer.
Wind slabs that have been triggered in the last couple days have provided enough weight to &quot;step down&quot; to the basal weaknesses.
The basal facets are weaker below tree line as many whumphs noted. Where the snow is deeper at higher elevations, the mid-pack is bridging the weak basal facets; however, snowpack depth varies so much that its hard to inspire confidence in stability.
Wind slabs of variable thickness and hardness dot the landscape. Many windpressed and stripped features will be encountered once you leave the shelter of the trees. Triggering this could dig down to the basal facets increasing the consequence.

Be conservative with your terrain selection and consider steep or unsupported planar slopes carefully. Assess the snowpack often: the variable nature of the snowpack makes it hard to avoid shallow areas where triggering may be more likely.
These old, hard slabs still deserve respect especially in steep or unsupported terrain. Remember that triggering these surface slabs may create enough load to pull out a larger deep persistent slab. Triggering may be easier in warmer periods.
With mild temperatures and strong solar radiation any snow near rocks could easily release. The large load created by a falling cornice could trigger the deep persistent slab.
The weak and unpredictable snowpack persists in the Lake Louise area and eastern side of the forecast region, where all steep terrain remains suspect. This problem is much less prominent west of the Divide, where the snowpack is deeper and stronger.
Areas at treeline and higher elevations have been blasted by the winds. This has created wind crust on the surface, and windslab avalanche problems in steep, windloaded areas.
Last weeks storm left us with widespread winds slabs up high. They have been largely unreactive to rider testing however areas they could be triggered are on steep unsupported slopes, slopes nearing ridge crests or on convex rolls.
The November persistent weak layer will need a large load to be triggered (i.e. cornice fall). Its distribution is waning but sill lingers in isolated spots.
Natural activity has tapered off on this layer, but it is still possible to trigger big avalanches in shallow locations.
Cross loaded gullies may be the most attractive after the intense wind scouring in the alpine, but careful evaluation is essential to check for the presence of touchy windslabs.
Thin areas and steep terrain that has not  yet avalanched should be avoided. Thicker moderate angled terrain  with low consequences would be a good choice.
These slabs are fairly isolated now, but could cause a deep step down avalanche if triggered.
There may still be a few lingering slab pockets in steeper, unsupported features that could surprise a person. This being said, there has been little activity observed on the surface windslabs,
The November persistent weak layer will need a large load, like a cornice, to be triggered. The isolated nature of its distribution makes it hard to forecast for this layer.
Low likelihood, high consequence. This means the chance of triggering is decreasing, however, if you do, it will be a big slide.

The snow from Wednesday is starting to build new windslabs. These will be touchy for the next few days until the begin to settle. Previous windslabs are also a concern underneath this new snow. These could be triggered from the many thin areas.
Be conservative with your terrain selection and assess steep or unsupported planar slopes carefully. The new snow may be hiding shallow areas where triggering may be more likely and with the variability in snowpack there are many thin areas.
Temperature inversion with warmer air at ridgetop and strong solar radiation will weaken snow in steep rocky areas. A falling cornice could create the large load needed to trigger a deep persistent slab so be conscious of what is overhead.
A little bit of new snow has buried a large surface hoar layer. This sits on a smooth bed surface; windslabs or suncrusts. This is likely to be triggerable on steep terrain. In addition, loose avalanches are expected to be triggered by strong solar.
The November persistent weak layer will likely need a large load to trigger it, like a cornice. This is the classic low probability-high consequence problem. It's patchy distribution makes it hard to forecast, but if it wakes up watch out!
Triggering of the basal depth hoar/crust will be most likely from thin snowpack areas. These are harder to trigger now, but if you hit the &quot;sweet spot&quot;, the avalanche will be full depth and large consequence.

The weak facets at the base of the snowpack have not gone anywhere. But, time and settlement seem to have brought the snowpack into balance. Isolated, large avalanches may still occur, particularly in areas that have not avalanched previously.
You are more likely to trigger this layer below treeline where the upper snowpack is more consistently shallow and weak. You still need to be cautious in shallow areas above treeline.
The basal facets are lying dormant for now. However, the possibility of triggering from a weak spot (thin, shallow, rocky area) remains real.
Park staff were able to ski-cut small, hard wind slabs in steeper alpine and tree-line terrain yesterday. These pockets moved quickly on the underlying hard surface, and would be a concern in &quot;no-fall&quot; terrain, as they could sweep you over cliffs.
It is a classic Rockies problem of low likelihood, high consequence when dealing with the basal depth hoar/crust. No activity has been seen on this layer in a week, but where the snowpack is thin, your likelihood of triggering a slide will increase.
Odds are you will not be able to trigger this layer from fat areas in the snowpack. It exists at all elevations and aspects and the variability in the snow pack is so widespread it does not inspire confidence anywhere in the terrain.
5cm of snow will bond poorly to the various surfaces; sun crust and surface hoar; it has buried. Expect sluffing in steep terrain. Be cautious in terrain like confined gullies, where snow can accumulate deeper, or exposed areas over cliffs.
Moderate winds, from variable directions, will transport the new snow, forming slightly deeper soft slabs along ridge crest and breaks in terrain. These soft slabs will bond poorly to the surfaces below. On exposed alpine slopes they bury hardslabs.

Old and new variable wind slabs are present at alpine and tree line elevations. It is possible to trigger isolated pockets of wind affected snow on steep roll overs.
This problem continues to exist at the base of the snowpack, but triggering is unlikely due to a combination of time, settlement and the bitter cold - all of which have combined to lock up the snowpack. It will reawaken once the weather changes.
This layer is well bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain.
Winds have redistributed some of the new snow creating a soft slab that was seen to react to rider triggering. Watch for this are on steep convex rolls with a buried sun crust. Shooting cracks from your ski tips is an indicator of this instability.

This layer is well bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain.
A lack of avalanche activity and hard test results show that triggering the weakness at the base of the snowpack is unlikely, however the variability in snowpack depth means it is worth watching for thin areas where triggering may still be possible.&nbsp;
The recent snow has created thin wind slabs in the alpine and at treeline which could be a problem in steep confined terrain such as gullys and couloirs.
Expect to see some wind loading on south and west aspects, not typical of this area. The new snow has not bonded well to the old surfaces and was reactive early this week to rider traffic. People could expect the same but with a stiffer windslab.
This layer is well bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain or by a large load.
The snowpack has gained some strength and now combined with the cold temperatures it will be hard to trigger an avalanche on the weak layers near the base. This situation will persist until the weather pattern changes.
Expect to see some thin slabs on S and W aspects in the alpine and exposed tree-line elevations, due to cold Arctic winds blowing from the N and E. These slabs will be stiffer with the cold weather, and have not bonded well to the older surfaces.
This layer is well bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain or by a large load.
The snowpack has gained some strength and now combined with the cold temperatures it will be hard to trigger an avalanche on the weak layers near the base. This situation will persist until the weather pattern changes.
Riders are still able to ski-cut thin (5-10cm), hard slabs in lee features. With the reverse loading of N and E winds, slabs can be found on all aspects. While the slabs are likely too thin to bury a person, they could push one over steep terrain.
This layer is bridged by a strong midpack. Keep in mind that shallow locations could produce a failure in this layer which would step down into the facets and slide full depth.
The 40 cm of snow sitting on the ground continues to loose strength. The mid-pack that is holding everything together varies greatly in depth. Use your probe to verify that you are traveling in fat areas and use extra caution if you are not.
Variable wind directions over the last few days have created thin and soft slabs in a wide range of open areas. Surface snow is faceted which is  discouraging slab formation. These slabs sit on weak snow over firms surfaces: keep them in mind.
Thin wind slabs exist in exposed tree-line and alpine lee features on all aspects. It is possible for riders to trigger isolated pockets.
This layer may become reactive if there is a sudden temperature warming through the day.&nbsp;
Thin pockets of wind slab are present on exposed treeline and alpine lee features. North and east winds have created reverse loading conditions.
This layer may become reactive if there is a sudden temperature warming through the day.

This layer may become reactive if there is a sudden temperature warming through the day.&nbsp;
This layer may increase its reactivity if there is a sudden temperature warming through the day.
Any new snow or wind slabs will be sitting on a mix of facets, surface hoar and sun crust. This has potential to create a good sliding layer. Watch for sluffing in steep terrain starting Tuesday, and deeper storm slabs failures by Wednesday.
As new snow falls and is redistributed by W winds, expect slabs to form quickly or to&nbsp; contribute to soft windslabs that already exist&nbsp; at Treeline and above. In recent days even very soft slabs have failed easily over weak, faceted surface layers.
In terrain over 40 degrees skiers may easily sluff the Surface Snow which will continue to gouge out a trough until it hits lower angled terrain. These events occur naturally in very steep terrain. Expect this to get worse with more snow.
This weak snow under the entire snowpack remains a concern especially in thin areas. As warming and loading occurs, avalanches described in the problems above could provide a large load triggering larger events on this layer.
35cm of new snow has fallen onto a surface that will not bond easily. Triggering avalanches will not be difficult due to the nature of the recently buried weak layers.
Winds have picked up with lots of light snow available to be pushed around. Expect wind slabs to continue to form at higher elevations as the day progresses.
This layer may increase its reactivity if there is a sudden temperature warming through the day.
Soft slabs are forming rapidly with the new snow over a very weak and widespread layer. These slabs can be triggered from a distance on steep slopes and require very conservative terrain selection and route finding.
With widespread avalanches occurring the potential for the weak snow at the bottom of the snowpack to be triggered as a large avalanche is elevated. Give big terrain a wide berth until things have a chance to settle.
By Wednesday there may be up to 25 cm of new snow being blown into fresh windslabs. Fresh slabs like this are touchy, and in places their depth may exceed 50 cm. Be very careful in all windloaded areas, and looks for clues and cracking under foot.
50-60cm of storm snow overlies an old surface that will not bond well. Temperatures have increased and winds have picked up, creating stiffer slabs that are ripe to fail.
Winds have picked up from the W/SW and there is 50-60cm of new snow available for transport. Expect wind slabs to continue forming in lee areas at all elevations.
Large sluffs can be expected in steep terrain. They are likely to gain mass and move quickly. Take extra care above and below terrain traps.
Bridging above this layer makes it stubborn to initiate; however, it will be big when it goes. A sudden warming, large additional snowload, large triggers, or surface avalanches may tip the scale. Be aware of thin locations as likely trigger spots.
15cm of new snow with variable wind directions and speeds have translated to wind loaded pockets of storm slab potentially 45cm thick overlying weak surface facets. More snow Thurs-Fri will add to this condition. Loose avalanches are also possible.
There has been no avalanches on this layer for two weeks.&nbsp; It is very unlikely this layer will be triggered while we remain in the Arctic high weather system.&nbsp; This layer will wake up again with more snow and wind loading.
The 10-20 cm of new snow has created touchy windslabs up to 30 cm thick with impressive propagations for their small size.
The new snow now has enough cohesion in some locations to act as a soft slab on steeper features not affected by the wind.
The storm slab overlies a weak surface and is not bonding well. Many avalanches have already slid on this interface, but if a slope has not released, it should be considered a ticking time-bomb.
Wind slabs continue to develop in lee features at alpine and tree-line elevations. There is plenty of new snow to feed the wind slab development, so if winds pick up in the area you are skiing, expect the danger level to bump up a notch.
The low density fluff that sits in protected tree-line and below tree-line elevations is sluffing fast in steep terrain. Expect it to gain mass and accelerate as it moves downhill. Take care above and around terrain traps.
New snow with variable wind directions and speeds have translated to wind loaded pockets of storm slab potentially overlying weak surface facets. Loose avalanches are also possible.
Touchy slabs are building and stiffening over a combination of facets, surface hoar, and sun crust on solar aspects. As the stiffness of the slabs increases, so too will the distance they propagate.
Wind and warm temperatures have created higher density snow over the weak faceted crystals in almost any open areas. Very easy triggering means that skiers should treat all significant slopes with respect. SE to SW slopes seem extra touchy
The slab of well settled snow that protects the weak snow at the base of snowpack is not very thick in many areas. As the storms continue to place stress on the snowpack, and with significant surface avalanches expected, larger events could occur.
The storm slab is just getting thicker and heavier on the underlying weak interface. Any large, open slope that has not slid should be treated with caution, as it awaits just that extra amount of load from a person.
Strong winds in the alpine have redistributed the copious amounts of new snow into very touchy wind slabs. Expect to find extensive cracking and whumphing under your boards where the wind has affected the surface.
Sluffing from steep terrain will gain mass and speed. Given the new amounts of snow, sluffing is a certainty, so use caution above terrain traps. Stop periodically and move to the side, allowing that freight-train of pow to pass you by.
Pockets of wind loaded slab overly weak surface facets in sheltered areas at tree line and above.
Touchy slabs continue to build and stiffen over a combination of facets, surface hoar, and sun crust on solar aspects. Large propagations (upto 300 m) and several skier remote triggered avalanches to size 2&nbsp; were observed today in KNP.
This layer is still touchy. Avalanche control was producing results on this layer today on the Sunshine Road and 93S.
Recent slab formation overlies a persistent weak layer of surface hoar, facets and crusts found predominantly at treeline and below. This layer is going to become more reactive with the next pulse of snow which begins on Saturday night.
These recently formed slabs have proven to be very easy to trigger failing naturally and with light loads. Limit your exposure to significant slopes. Do not get taken by surprise by the long propagations that are occurring.
Do not forget that there is weak snow under the entire snowpack. In shallow areas this faceted snow has continued to weaken and the slab above it that is holding the snowpack together has become stressed by recent loading.
A 100 cm storm slab sits on a weak layer.&nbsp; Skiers and riders will likely trigger this layer in avalanche terrain.&nbsp; Remote triggering is a concern, watch out for adjacent slopes.
Exposed terrain will have wind deposited snow forming slabs.&nbsp; Moderate to strong winds this AM are rapidly loading avalanche start zones.
Touchy slabs have been found primarily on East facing terrain below ridge crests between 2000 and 2400m.  These slabs are sitting on a persistent weak layer of crust and facets and are stiffening up, increasing the likelihood of wide propagations.
New windslabs are forming and adding to the load on lee aspects, primarily East facing terrain. Small windslabs may trigger deeper persistent slabs and increase the consequence of involvement.
This layer is still touchy. Expect it to be most reactive on south aspects near tree-line. Typically, it will be about 40cm thick.
These recently formed slabs have proven to be very easy to trigger failing naturally and with light loads. Limit your exposure to significant slopes. Do not get taken by surprise by the long propagations that are occurring.
Do not forget that there is weak snow under the entire snowpack. In shallow areas this faceted snow has continued to weaken and the slab above it that is holding the snowpack together has become stressed by recent loading.
20cm of additional load overnight totalling 1.2m over a weak layer which has been very reactive this past week. Riders have reported cracking, whoomphing and avalanches on this layer. This is in addition to any shallower storm snow instabilities.
Winds from the current weather pattern have been steadily in the moderate to strong range. Expect to see more slabby conditions at higher elevations reactive to human triggering.

The interface between rapidly settling storm snow and the previous surface is characterized by crust and facets and new slabs are touchy in specific terrain - particularly steep, lee aspects below ridge crests.
Recent Southwest winds have created new windslabs.  Caution is warranted with crossloaded gully features.
The recent storm snow is settling and bonding to itself. There is still a poor bond at the storm snow interface (facets and surface hoar) down about 30-40 cm.
As the slab over the weak layers down 100-140cm becomes more cohesive, it changes in how it reacts to a riders weight. The highly reactive stage may have passed but it is at a depth where triggering will be less frequent but much more dangerous.
We had strong winds yesterday morning and there's a concern the associated instabilities still exist up high.
The interface between rapidly settling storm snow and the previous surface is characterized by crusts. facets and surface hoar. New slabs are touchy in specific terrain - particularly steep, lee aspects at treeline and sub alpine elevations.
Recent southerly winds have created new windslabs. Caution is warranted with lee and crossloaded features.
The storm snow is starting to settle into a cohesive slab. As the slab stiffens, the weak layer will get harder to trigger, but the consequences will be greater. The nature and distribution of the weak layer means it will be with us for a while.
As the slab over the weak layers down 100-140cm becomes more cohesive, it changes in how it reacts to a riders weight. The highly reactive stage may have passed, but it is at a depth where triggering is less frequent but much more dangerous.
Strong winds overnight from the S-SW will have created surface wind slabs in the alpine and tree-line.
The persistent slab interface is a combination of crusts, facets, and surface hoar overlying a solid midpack bridging weak basal facets. It will be large if triggered. Caution on steep lee treeline and subalpine aspects with variable snow depths.
Caution on East aspects above treeline especially at ridgecrest transitions. Field patrol in Maligne area triggered size 2 of this nature where wind has firmed the recent storm snow into a windslab overlying previous layer of facets and surface hoar.
The recent storm snow is settling but a poor bond still exists on the storm snow interface. Natural activity has decreased but it is still possible for skiers to trigger this layer.
Recent SW winds have created touchy wind slabs on lee alpine and treeline terrain. These wind slabs are reactive to skier triggering.
The storm slab, which is 100-140cm thick and overlies a weak interface, is becoming more cohesive. However, the bond to the underlying interface is not showing much improvement. Skier triggering of this layer will have high consequence.
Fresh wind slabs from the previous couple days are evident in open alpine and tree-line elevations. Cracking and whumphing indicate that you have found them!
This persistent weak layer consists of facets and surface hoar that were covered. It sits on a mixture of crusts and firm supportive snow. This seems to be of most concern at the Treeline and lower alpine elevations between 2000m and 2400m.
Lee aspects of ridgetops and terrain features should be carefully evaluated for windslabs.
A poor bond still exists between the storm snow and the Feb 10 interface. This interface is reactive to skier triggering. (see avalanche details)
Continued SW winds have created fresh wind slabs in the alpine
These recently formed slabs have proven to be very easy to trigger failing naturally and with light loads. Limit your exposure to significant slopes. Do not get taken by surprise by the long propagations or remote triggering that has been seen.
Do not forget that there is weak snow under the entire snowpack. In shallow areas this faceted snow has continued to weaken and the slab above it that is holding the snowpack together has become stressed by recent loading to the point of failure.
This problem is becoming increasingly challenging. The clues of instability, like cracking and whumphing are tapering off, but tests and continued avalanches indicate that this thick slab is triggerable and will produce very large avalanches.
Winds during the last week have transported the new snow, loading lee slopes and forming cohesive wind slabs. In areas where the snow is more cohesive, triggering of these slabs is likely. If triggered these slabs will likely step down deeper.
This persistent weak layer consists of facets and decomposing surface hoar under 30cm of surface snow. It sits on a mixture of crusts and firm snow. It is of most concern at treeline and subalpine zones between 2000-2400m.
Where ever the wind has buffed the surface into a slab should be carefully evaluated particularly ridgetop transitions. Pockets of slab have also been created by valley bottom winds and have been found in exposed locations at treeline and below.
There is still a poor bond between the storm snow and the Feb.10 layer of facets and surface hoar. This interface is still very susceptible to human triggering.
Wind slabs have been forming at higher elevations from SW winds over the last few days.
A strong slab overlies a very weak layer buried down 1-1.5m. The snowpack now demands your respect, if you trigger this layer a large, high consequence avalanche will result.&nbsp; Use caution in shallow snowpacks, where triggering is more likely.
Use caution as you transition into exposed terrain.&nbsp; Triggerable wind slabs may be present on lee features.&nbsp; If triggered these slabs may step down to trigger deeper instabilities.
The persistent slab overlies 2 main weaknesses that will not go away anytime soon. A decomposing surface hoar-surface facet layer 30cm down and thick layer of basal facets-depth hoar. Its spatial variability makes it difficult to predict.
Carefully evaluate ridgetop transitions where winds have buffed the surface into a slab. It rests on the suspect surface hoar-surface facet layer 30cm down. Valley bottom winds have created slab pockets in exposed locations below treeline.
The storm snow interface down 40-70 cm still producing easy to moderate results. Natural cycle is over but still possible for skiers to trigger this layer.

This problem will take a while to heal and requires good terrain management. Be particularly weary of open unsupported slopes and convex rolls below tree line.
Snowpack tests on this layer today produced easy results. Despite the easy results no avalanche activity was noted. This is a layer to approach cautiously over the next few days.
Evaluate ridge top transitions where winds have buffed the surface into a slab. It rests on this suspect layer 30cm to 45cm down.
The strong mid-pack is bridging the layer well through the forecast area. Its spatial variability over the terrain does make it difficult to predict and snowpack tests show it to be very weak. Be careful in shallow start zones.
The 1-1.5m slab over the weak layers continues to settle and become more cohesive. This problem will take a while to heal and requires good terrain management. Be wary of open, unsupported slopes and convex rolls, particularly at tree-line and below.
The Feb.10 interface of weaker crystals is slow to gain strength. Slab properties above this layer are becoming stiffer, and human triggering is very possible. These seem to be the most touchy on solar aspects where there is a buried suncrust.
At higher elevations wind slabs will be more abundant and thicker, similarly in cross winded valleys existing glacial terrain. The Feb 10th weakness has recently been found down 20-70cm between 2,200m-2,400m, but is hard to trigger.
We have seen very few avalanches from this layer in the past 2 weeks. A strong midpack , when present, prevents triggering from all but the largest loads. Where the snowpack is shallow triggering will be considerably easier.
The 1-1.5m slab overlying the Feb 10th weak layer is slowly bonding to this interface, but is still reactive in tests. This problem requires good terrain management, such as avoiding large convexities and sticking to supported features.
Carefully evaluate ridge top transitions and start zones where the winds have pressed the surface into a slab. This slab rests above a persistent facet layer 30cm to 45cm down.

Now 80 to 130 cm thick, these slabs threaten serious consequence. While the potential for triggering has dropped, do not get taken by surprise: long propagations and remote triggering may still be possible. Limit your exposure to significant slopes.
A weak, persistent layer is buried under a thick slab. This layer is becoming more difficult to trigger, but if triggered will propagate widely producing a very large avalanche. Choosing appropriate terrain is key in managing this problem.
Moderate north winds have begun to load and stiffen up the surface slabs in open areas. This slab rests above a persistent facet layer 30cm to 45cm down.
The strong mid-pack is bridging the layer well through the forecast area. Its spatial variability over the terrain does make it difficult to predict and snowpack tests show it to be very weak. Be careful in shallow start zones.
The Feb 10th layer continues to produce sudden collapse test results in many areas. The cold temperatures will tighten things up a little and begin to weaken the slab over this layer but it is still a concern in many of the areas in the park.
As this weak layer, buried down around 1 m, gains strength human triggered avalanches are still possible. Areas of concern are open, unsupported slopes, convex terrain and thin snowpack areas.
Moderate north winds have stiffen up the surface slabs in open areas. This slab rests above a persistent facet layer 30cm to 45cm down.

The Feb. 10th layer is still a prominent feature in the snowpack producing variable results. We are seeing less activity over the past few days, but is still a concern in many regions of the forecast area.
Recent winds combined with cold temperatures have created widespread 10-20cm thick wind slabs up to pencil stiffness. These will be smaller in size and wont be a problem for a long time, but are a concern in steeper unsupported terrain.
As this weak layer, buried down around 1 m, gains strength human triggered avalanches are still possible. Areas of concern are open, unsupported slopes, convex terrain and thin snowpack areas.
New snow is expected to come in steadily with south winds and may slowly overload this interface. Watch for a reverse loading pattern from the south to north aspects because of the shift in wind direction.
This layer is slowly gaining strength however test results continue to show that wide propagations are possible in some areas which would lead to severe consequences. Sudden collapse results and low scores in propagation saw tests are still common.
Yesterdays North winds created thin windslabs in many locations which are now covered with new snow. The increasing W winds will also build new winds slabs over the next two days. Probe for these with your poles and avoid steep wind loaded slopes.
Soft slabs can be expected at higher elevations which is sitting over a weak layers of sun crust and facets. As winds and snow amounts increase this slab will tighten up and become more reactive.
Expect fast sluffing in steep terrain today capable of gaining mass. Exercise good group management such that people aren't riding below or above one another
The sun crust/surface hoar layer down 1-1.5m is still producing hard sudden results in snowpack tests. This indicates that the layer is difficult to trigger but will propagate widely if it does.
These slabs became less sensitive with cold temperatures and increasing depth. Now as conditions change with rapid loading and warming, limit your exposure to significant slopes. Do not get taken by surprise. Long propagations may still be possible.
Variable winds have been actively creating windslabs over the last week. Now with more snow and moderate to strong SW winds in the forecast, expect to encounter slabs as you enter open terrain.
This layer is slowly gaining strength however test results continue to show that wide propagations are possible in some areas which would lead to severe consequences. Sudden collapse results and low scores in propagation saw tests are still common.
The new snow and moderate SW winds are staring to build soft slabs in lee areas above tree line. Probe for these with your poles and avoid steep wind loaded slopes. Sluffing out of steep terrain is also expected as more new snow arrives.
Steady snowfall and light to moderate winds may produce new windslabs in exposed areas.
Soft slabs exist at higher elevations. They sit atop a variety of surfaces (suncrust, facets, wind slab), and have been touchy to human-triggering. As more snow falls and the temp's warm up, expect them to become cohesive and more reactive.
The low density snow from the past 2 days will sluff fast and gain mass in steep terrain. Practice good group management and avoid knocking your buddies, or yourself, over by your sluffs.
The suncrust/surface hoar layer down 1-1.4m is still producing hard, sudden results in snowpack tests. This indicates it is stubborn to trigger, but if initiated, it will propagate widely, producing large avalanches.
New low density storm snow is shedding from steep terrain in the alpine and may have enough mass to ruin your day.  Expect sluffing on steeper slopes at all elevations.
Although winds are expected to remain relatively light, there have been several wind events in the past 48 hours with shifting gusty winds in the moderate to strong range that may have produced new windslabs at upper elevations.
This layer is gaining strength but tests and whumphing still show there is potential for wide propagation in some areas.&nbsp; Any avalanche on this layer could lead to severe consequences.
Soft to hard windslabs, generally 30 cm thick, can be triggered in lee terrain.&nbsp; In steep terrain, the snow is gaining cohesion to act like a storm slab. The new snow sits on a low density cold layer of snow that will take several days to bond.
Several loose snow avalanches were observed pouring over cliffs today to size 1.5.&nbsp; Winds will continue to be gusty for the next 2 days. Pay attention to terrain over head.
Field teams found touchy soft slabs in open alpine and tree-line lee features yesterday. These slabs appeared to be failing within the new snow, but some were popping very easily off the suncrust on solar aspects.
Fast-moving sluffs triggered by riders continue to be reported. These sluffs have been gaining mass in steep terrain, and could easily bowl you or your buddies over.
Lingering deep (1-1.4m) in the snowpack, the surface hoar/facet/crust sandwich continues to produce hard, sudden results in tests. If a large enough trigger gets this layer to fail, avalanches will be very large.
Steep alpine faces are sluffing regularly as new snow accumulates.
This avalanche problem remains a concern and may become more sensitive to triggering as temperatures rise and penetrate into the snowpack.
Lots of fresh snow and moderate southerly winds have created touchy wind slabs 40-60 cm deep in the alpine.
Test results on the Feb 10 layer generally in the moderate range but still show lots of potential for good propagation if triggered. Recent storm snow may be enough to activate this layer (see avalanche details). Lots of uncertainly with this layer
A touchy slab lurks on the slopes, and were easily triggered by field teams and artillery control at all elevations. As it becomes more cohesive from snow-load and warming temp's, we expect this slab to propagate easily.
Plenty of new, loose snow is available for sluffing in steep terrain. Practice good terrain and group management, and avoid getting pile-driven into terrain traps by the snow you just skied.
The facet/crust &quot;sandwich&quot; is buried 120-150cm below the surface now. It is still producing hard, sudden results in tests, indicating that it can will propagate if a large enough trigger hits it. Avalanches digging into this layer will be large!
Little wind has accompanied the new snow of the past two days. Sluffing out of steep terrain may be of concern, particularly for ice climbers.
This problem has yet to materialize in full force, but with rising temperatures and forecast winds we expect this surface condition to become quite touchy over the weekend.&nbsp;
Test results on the Feb10 layer mainly in the moderate range with potential for wide propagations if triggered. The recent snow has been shown to overload this layer in the Kootenay,Sunshine, Yoho areas, and less so in the Louise region and Hwy. 93N.
Lots of recent snow and moderate westerly winds have created touchy wind slabs 40-60cm thick in many wind exposed areas.
Up to 55cm of new snow has arrived over the last week. Warm temperatures are helping it settle but it is siting on a variety of sun crust, old windslab or facets. Warm temps on Sun could provide a trigger for this layer.
Moderate to strong westerly winds have been building windslabs on lee slopes below ridge crests in the alpine and at treeline. These will continue to build over the next few days. Expect to encounter slabs as you enter open terrain.
These slabs became less sensitive with the increasing snowpack depth. As temperatures warm to ridgetop for Sun limit your exposure to significant slopes. Do not get taken by surprise. Long propagations may still be possible.
Warming temps through the storm created a punchy storm slab that is sitting on a variety of weak surfaces. Avalanche control proved that this slab is reactive and produced large avalanches. The slab may be more reactive in wind-exposed terrain. 
This last storm, and the forecast dump of snow this weekend, may wake a weak persistent layer up. This layer, buried ~1.5m deep, is still reactive in snowpack tests and if triggered will produce very large and destructive avalanches.
Sluffing out of steep terrain is a concern, particularly for ice climbers. Loose slides are overloading the snowpack in the alpine and have triggered slabs below.
Open areas at tree line and above are beginning to show signs of wind effect and slab development.

There are thin windslabs from the last storm on lee features that are reactive to explosives (size 1-2). Expect new windslabs to develop with incoming snow and wind over the weekend.
60 to 80 cm of warm/moist snow has formed a rider triggerable slab. Natural avalanches are expected this afternoon with rising temperatures and more snow load. Remote triggering is also a concern, watch out for adjacent slopes.
A deep weak layer buried at the end of January is down around 1.5 m. Although we have not observed any recent skier-triggering of this layer, artillery control triggered this layer on the west side of the park, releasing a size 3.5.
Recent storms with warm temps and West winds have created slabs and built cornices. Wet slabs are failing BTL and solar aspects, cornices and windslabs are failing at TL and above.
The weak February facet layer is now buried up to 170cm deep. Large loads such as cornices have triggered this layer where it is deep and it has failed with sluffing and heating where it is shallow. Long propagations are possible with this layer.
Solar heating will likely result in these events occurring to ridge tops Saturday. Warm temps as well as the rain expected Sunday will cause these events at low elevations. Be aware that these small events may act as the trigger for deeper slabs
Storm snow showing dangerous slab properties, use extra caution when entering steep open areas.
Wind slabs more prevalent in the Ice Fields area where moderate SW winds and mild temps have created touchy slab properties in all open areas.
Dense snow is overloading the Feb.10th interface and will continue through Sunday. 
Strong winds, new snow and warm temperatures are forming wind slabs in lee terrain and are likely to be triggered with light loads such as a skier.
We have seen the basal facets wake up at lower elevations in the Kootenay area. This may not be widespread, but will cause large avalanches if initiated.
80 to 100 cm of warm/moist snow has formed a rider triggerable slab. We are currently seeing natural avalanches in the storm snow, some running to end of runnouts. Minimize your exposure today by skiing in mature forest.
A deep weak layer buried at the end of January is down 1.8 to 2 m.&nbsp; Smaller avalanches could step down and trigger as large, high consequence avalanche on this layer.
Very little natural activity has been observed in the storm snow in the lower elevation bands. Loose wet slides will become the concern as the storm passes and the sun bakes the solar aspect.
We have had very limited observations in the alpine due to visibility. Be especially cautious as you approach open areas and ridge crests with visible wind effect.&nbsp;
The recent storm snow and wind slabs will slowly begin to bond to the lower layers in the snowpack but this will take some time. Choose conservative terrain with no overhead hazard until this has a chance to bond.
The Feb 10th layer continues to be reactive in many areas especially at tree line. Avoid any steep terrain until this has a chance to bond.
With the cooling temperatures this will become less reactive to skier traffic. Large triggers such as cornice drops or large slab releases could still cause failures on the basal facets.
30cm of heavy snow with wind fell yesterday over much cooler and lighter snow. This combination is what caused a large avalanche cycle. Storm snow instabilities will still exist in the upper 1m and will need some time to bond to be trusted.
A sun crust down ~1m is well within the range of human triggering on south and west aspects. The February surface hoar/crust layer down ~1.5-2m which can reawaken with a heavy trigger such as a large cornice release.
There has been several avalanches observed&nbsp; running in the recent storm snow. Avalanche control produced 30 - 70 cm thick slab results on NE aspects.

In thinner snowpack areas, many avalanches are initiating as a storm or persistent slab and are stepping down to this layer.
The storm slab will settle over the next few days, but is currently very touchy. Most avalanches are initiating on this layer and quickly stepping down to the deeper weak layers.
Storm snow instabilities are present from snowpack tests yesterday. There is wind affect above treeline and lingering windslabs may exist in exposed areas.
2 buried weak layers have been reactive this week. Down ~1m, is a sun crust on south and west aspects. The other is the other is Feb. surface hoar/crust layer down ~1.5m-2m which still shows wide propagation potential in snowpack tests.
There has been several avalanches observed running in the recent storm snow.
Very warm temperatures and rain to 2300 meters on March 8 and 9 has settled the near surface instabilities with cooler night time temps. Thin wind slabs may be present in some aspects on this layer.
The weak facet layer is now buried by up to 170cm in treeline and alpine areas and below treeline is found down 50cm. Many avalanches fell over the weekend on this layer and it is a concern that may persist for some time. Triggering is possible!

Storm slab is still touchy and has potential to step down to deeper persistent layers.
The recent wind slabs from the latest storm are settling out, but they will be stressed by today's sun and rapid warming. The first couple of hours of intense sun will likely bring activity to this layer.
There are two layers of concern. The first is a sun crust on S-SW slopes, buried ~1m deep. The second is the Feb 10 surface hoar/facet complex, down 1.5-2m. Both exhibit sudden failures, meaning there is potential for wide propagation.
The recent storm snow, redistributed by wind is now over loading the snowpack. Several skier remote avalanches were observed today.
Natural activity has slowed down on this layer, but we have seen large avalanches over the past few days with the new storm snow overloading the Feb.10th interface. In some cases we have seen this step down to the basal facets in thin snowpack areas.
Mod to strong Westerly winds will be stiffening the snow surface and transporting snow to lee aspects. These will be sensitive to human triggering for the next few days.
Watch locally for daytime warming in steep, solar features.
The surface slabs are settling out and bonding to the older interface, but if the temperatures rise more than forecasted, expect touchy conditions on south and west aspects.

The recent storm snow, redistributed by wind is now over loading the snowpack. A field team in the Icefields area yesterday remotely triggered several slab avalanches and experienced extensive whumphing at tree line elevations.
In thinner snowpack areas, this layer is still touchy as shown by numerous large whumphs and sudden collapse results today. It is especially reactive on solar aspects where there is a buried sun crust and may be less reactive in deeper snowpacks
Recent moderate to strong west winds have stripped fetches and loaded the lees. Lee slopes will be quite touchy and the loading may be enough to trigger natural avalanches

Lots of new snow, with wind, through the weekend will form a new storm slab. This slab will likely be most reactive where it overlies suncrust, but will also bury small surface hoar. If triggered, this slab may also step down deeper.
New snow Fri is starting to build windslabs on lee slopes. The storm snow forecast for Sun/Mon will build these deeper. These will need some time to settle.
With freezing levels climbing during the daytime, precipitation at lower elevations will be wet snow or rain. Loose wet avalanches will be likely depending on the amount of snow and if rainfull is heavy wet slab avalanche will also be a concern.
The layer down 70-170 cm is still active as demonstrated Thur with avalanche control work up Akamina. Any slope not yet slid should be a concern. Windslabs, cornices, storm slabs or wet loose avalanches could step down and result in large avalanches.
This layer is still touchy in thin snowpack areas (especially where there is a buried sun crust), and large whumps and sudden collapse results have been found. With limited observations this layer now seems less reactive in deeper snowpack areas.
Lee slopes will be loaded from recent strong westerly winds. With more wind and snow in the forecast, these wind slabs will increase in likelihood and size through the weekend.
With the new snow, expect the Feb 10th layer of facets, surface hoar, and some buried sun crust to &quot;wake up&quot;, especially in thin and variable snowpack areas.&nbsp;
We will have wind slab development in any exposed areas with the new snow and forecasted mod-strong west winds.&nbsp; Failure of these may step down to the Feb. 10th interface.
We've had a significant amount of snow overnight. Combined with the mild temperatures, the southerly winds which have started to pick up and the crust which it sits on, the new storm slab will be highly reactive to human triggering.
This sudden heavy snow load is likely to reawaken the deeper persistent weak layers creating very large avalanches. Avoid crossing avalanche paths until the storm ends and temperatures cool down.
As yesterdays avalanche indicates, the basal weaknesses are still susceptible to human triggering. Use caution in steep, shallow areas that have not previously avalanched.
Although the new storm slabs are unlikely to produce very large avalanches they are still quite touchy.
Closely associated to the new storm slabs, wind-slabs will be located at higher elevations in direct lee areas. Because of wind transport the wind slabs will be thicker (up to 40cm) than the storm slabs and potentially more touchy.
A field team in the Icefields area on Wednesday remotely triggered several slab avalanches and experienced extensive whumphing at tree line elevations. Care is needed as you navigate slopes in this elevation band.
Where slab overlies the February 10th facet layer very touchy conditions exist. We have found this to be most prevalent at tree line elevations where remote and skier triggered avalanches have been occurring in the last few days.
Where wind slabs overly the February 10th facet layer very touchy conditions exist. This is borne out by numerous incidents of skier accidental and remotely triggered avalanches in the last few days.
The 35cm of snow that fell in the last day has been observed to travel far and fast when it fails. Loose snow slides are likely with any solar affect particularly at lower elevations.</span></p><p class="p_CC664AAA"><span class="s_AA239A9B">
65cm has fallen over the last 4 days with strong winds yesterday. On solar aspects this has buried a thick sun crust. Venturing out into larger terrain is not a good idea at this point as this new load will need some stabilization time.
Down around 1-1.25m is a buried crust from early March. Backcountry users have been reporting whoomphs and remotely triggering this layer prior to this latest storm. Extra caution on steep south and west slopes where the crust was well formed.
The February deep instability, down1.5m-2m will need a large trigger to be initiated. Although the sudden snow loading has ended, it may get triggered by a large cornice for or from a shallower avalanche.
Where wind slabs overly the February 10th facet layer very touchy conditions exist at tree-line and is borne out by numerous avalanche incidents in the last few days. The frequency of slabs stepping down to a deeper layer has increased dramatically.
The 35cm of snow that fell in the last day has been observed to travel far and fast when it fails. Loose snow slides are likely with any solar affect particularly at lower elevations.
The 30-40cm of snow from the last few days is sitting on crusts or moist snow that could provide a poor bond. Daytime heating could trigger these instabilities on south facing aspects but they may persist on cooler north aspects for a few days.
Previous windslabs are lurking just under the surface and now there is a lot of snow available for transport to start building new ones.
The chance of triggering the deep weak layers from early February are diminishing but these layers have not completely disappeared. Any slope that have not slid should be suspect for possible large destructive avalanches.
The Feb 10th layer continues to produce whumphs, natural and remote avalanches and skier triggered avalanches. It is especially sensitive in thinner or cross loaded snowpack areas and places with a buried sun crust.
The recent storm slabs are between 40 and 80cm thick. In general they seem to be bonding well but use caution in steep or wind loaded features.
Lingering storm slabs instabilities may exist from the last storm two days ago and the associated wind. 2 crusts have been recently buried by this. Caution in more exposed areas where the wind had a chance to stiffen the snow.
A weak layer from early March within the range of rider triggering may catch you by surprise. Triggering this layer is more likely on steep south and west aspects where the crust had a chance to fully form.
The deep instability from mid February , down around 2m will need a large trigger to be initiated like a cornice fall or shallower avalanche. It should not be overlooked by backcountry users due to the  large consequences should it be triggered.
We are seeing less activity with this problem as the days go by. It is still touchy and what is left is a low likelihood but high consequence situation if it is triggered.
The storms slabs will continue to settle. However, as they settle, they will become more cohesive and the likelihood of triggering will be the same for a few days yet.
The &quot;drought layer&quot; (Feb 10) has been sensitive in the past week, contributing to numerous large avalanches. Pay particular attention to moraines at treeline and crossloaded features in the alpine.
35cm of recent snow is settling rapidly. Although this snow appears to be bonding well, caution is warranted in steep terrain. It is a good idea to test the storm snow interface prior to committing to your line.
The recent storm snow has been redistributed by winds. The resulting soft slabs sit atop various old surfaces, including crusts on solar aspects and small surface hoar on northerly aspects. The slabs will remain reactive for a couple more days.
The early March crusts are buried by over a metre of snow, but are still triggerable by people. They are more likely to fail on steeper S and W aspects.
In Rogers Pass, the Feb 10 surface hoar/crust sandwich is buried over 2m deep. We are still seeing hard, sudden test results on this layer. If a very large trigger smacks the slope, there is the potential for a huge avalanche.

35cm of recent snow is settling rapidly. Although this snow appears to be bonding well, caution is warranted in steep terrain. It is a good idea to test the storm snow interface prior to committing to your line.
Activity on the Feb.10th of facets, surface hoar and buried suncrust is starting to taper off, and it is a lowered likelihood with large consequences scenario.  Some slides have been observed to step down to ground in thin snowpack areas.
Storm slabs formed in the last few days will be less sensitive to triggering as time goes on.  Forecast snow may build on these on Thursday.
The recent storm snow is settling into a cohesive slab, particulary in wind affected areas. Various weak layers within, and just below, the slab exist and may be triggered by skiers or snowboarders. It may become more reactive during sunny periods.
This layer is patchy which makes it difficult to predict. It is likely to be most reactive on solar aspects where it is comprised of a sun crust with surface hoar. If triggered it has properties and is deep enough to result in a large avalanche.
The late Jan/early Feb persistent weak layer is still active. Very large and impressive avalanches have been triggered by rapid loading during storms, avalanche control, and skiers remotely triggering (fortunately in a safe spot) from shallow areas.
The &quot;drought layer&quot; (Feb 10) has been sensitive in the past week, contributing to numerous large avalanches. Pay particular attention to moraines at treeline and cross-loaded features in the alpine.
Windslabs are forming in wind prone areas below lee ridgelines at treeline and above.
Another 15 cm of new snow fell on top of this past weekend's 35cm storm. Although this snow appears to be bonding well, caution is warranted in steep terrain. Test the storm snow interface prior to committing to your line.
Feb 10 shears tightening up in deep snow pack areas west of the divide. In shallower snowpack areas this interface still producing whoomphing and easy to moderate shears.
Recent snow combined with mild temperatures and West winds have created soft slabs. These slabs are sitting on a variety of surfaces including rain crusts, sun crusts, old wind slabs and the interface to the previous storm snow and are 25-40 cm deep
New snow is sluffing off of very steep terrain and moving with skiers on steep slopes. Manage your group carefully and be aware of your sluff. Avoid confined terrain features such as gullies where these small slides could focus and gain more energy.
Snow amounts have slowly been accumulating over the last few days and storm snow instabilities may catch you by surprise. Caution on unsupported slopes or wind affected areas. This new snow is likely to produce some fast sluffing on steep slopes.
This layer is deep enough to cause a large avalanche and shallow enough to be triggered by people, a dangerous combination. It's been most reactive on solar aspects where the crust is thickest and most likely to be triggered from shallow snow areas.
The deepest instability within our snowpack is down around 2m. Large triggers have produced very big avalanches on this layer into last week. It remains on our watch list, and it's another reason to avoid shallow snowpack areas.
Slowly this layer is becoming less reactive, but it remains a concern. Field tests, particularly on southern aspects, confirms this. It's now down 80-120 cm and more likely triggered from thinner areas or by larger loads.
A 5 cm thick suncrust with facets on top exists on solar aspects with moderate sudden shears and is down approximately 40 cm.. An avalanche triggered on this layer could step down to the Feb 10th layer resulting in a larger avalanche.
The &quot;drought layer&quot; (Feb 10) has been sensitive in the past week, contributing to numerous large avalanches. Pay particular attention to moraines at treeline and cross-loaded features in the alpine.
Windslabs are forming in wind prone areas like below lee ridges at treeline and above.
Trickling snow over the last 4 days amounted to 60cm at tree line. Instabilities in the upper snowpack from the recent snow load may exist particularly in exposed areas that saw some wind.
Reports of whoomphing and natural activity observed on this layer yesterday indicate it's volatility. This layer is deep enough to cause a large avalanche and shallow enough to be human triggered, a dangerous combination.
Large triggers have produced big avalanches on this layer, down ~2m. It remains on our watch list and it's another reason to avoid shallow snowpack areas.
We are finding moderate to hard sudden collapse results on the Feb.10 interface. Thin and variable snowpack areas will be the easiest places to trigger this interface.
A 5cm thick suncrust with facets on top exists on solar aspects with moderate, sudden shears down 40-60cm. An avalanche triggered on this layer could step down to the Feb.10 interface causing a larger avalanche.
The &quot;drought layer&quot; (Feb 10) has been sensitive in the past week contributing to numerous large avalanches. Pay particular attention to moraines at treeline and cross-loaded features in the alpine.
Windslabs are forming in wind prone areas like below lee ridges at treeline and above and cross-loaded gulley features.
Storm slab instabilities may exist and may pop with human triggering, solar warming and newly formed soft slab in the lee of ridge crests.
The Mar 2nd crust is dwn around 1.25m. The slab overtop the weak layers down 1-1.5m continues to settle and become more cohesive.
The Feb 10 layer may be a concern with very large triggers or thin snowpack areas in rocky terrain.
The &quot;drought layer&quot; (Feb 10) has been sensitive in the past week contributing to numerous large avalanches. Pay particular attention to moraines at treeline and cross-loaded features in the alpine.
Windslabs continue to form and be covered by intermittent snowfall. Pay attention to wind affected terrain above treeline.
The Feb 10 layer will be touchier in the Eastern portion of the forecast area, less in the West. In addition to Feb 10, the Mar 13 layer, a suncrust on South aspects, can be found down 40-60cm. Snowpack tests on this layer produced moderate results.
Storm slab instabilities newly formed soft slab in the lee of ridge crests may exist and pop with human triggering.
Snowpack tests yesterday show the Mar 2 layer down ~1m to still be reactive with large consequences if triggered. Shallow snowpack areas, like slopes that have lots of rocks poking out, seem to be the most likely areas for this to happen.
Another deep weakness in the snow pack is the February surface hoar/crust layer. Large triggers, such as a cornice fall or a running avalanche, will be needed to step down to this layer.

The Feb 10 layer is touchier in the eastern portion of the forecast area, less in the west. In addition to Feb 10, the Mar 13 layer (suncrust on south aspects) can be found down 30-60cm. Snowpack tests on this layer have produced moderate results
The late March sun is packing a lot of punch. If the sky doesn't cloud over tmrw, we may see some natural activity out of steep rocky solar terrain.
With significant warming Tue and  incoming precipitation for the rest of the week, expect these slabs to become more reactive. Small changes in aspect and elevation seem to change the nature of these slabs so monitor what you are skiing on closely.
Heating on Tuesday will effect steep solar slopes and features such as cornices or snow near black bodies such as trees or rocks. Similarly,&nbsp; with some potential for rain at low elevations Wednesday, be cautious with the slab over the buried crust.
The early March weak layer down ~1m is reactive in snowpack tests with hard sudden results. We still see sporadic large avalanche events that fail on this layer. Choose supported slopes that have uniform snow cover.
Deeper in the snowpack is the February surface hoar crust layer. Large triggers, such as heavy snowfall or cornice fall will be needed to get this layer to fail.
The &quot;drought layer&quot; (Feb 10) has been quietly dormant. Expected snowfall this week could 'wake' this layer up. Pay particular attention to moraines at treeline and cross-loaded features in the alpine.
Ever present in the forecast area, expect slabs in wind prone areas like below lee ridges at treeline and above and cross-loaded gulley features.
The Feb 10 layer is touchier in the eastern portion of the forecast area, less in the west. In addition to Feb 10, the Mar 13 layer (suncrust on south aspects) can be found down 30-60cm. No shears were found on Mt Field today during snowpack tests.
New snow overnight will have formed soft slabs in alpine and tree-line lee features. In wind-sheltered areas, it will likely be good quality skiing.
The early March weak layer is still reactive with hard, sudden planar results in tests. Sporadic large avalanche events are still occurring on this layer, so heads-up with the new loading overnight. Stick to supported features today.
Lingering deep in the snowpack is the Feb 10 surface hoar/facet/crust layer. A large event occurred north of Rogers Pass 2 days ago, reminding us that a large trigger could create a very widely propagating avalanche with devastating results.
Expect to find new slabs in wind prone areas on lee ridges at treeline and above and in cross-loaded gulley features. Loading continues in these open areas and can overload the slope quickly.
Lee features continue to load and the potential exists to trigger these deep instabilities. Carefully evaluate your time spent under overhead hazard before committing to terrain.
There are two layers of concern in the upper meter of the snowpack that continue to produce shears in isolated areas and have a high degree of uncertainty. Be very mindful of this problem in areas that have not previously avalanched.
Loose dry sluffs are running easily and gaining mass as they progress down the slope. Generally only small slides are anticipated, but watch your exposure to cliffs and trees as these can easily knock you off your feet.
Yesterdays new snow bonded poorly to the snow below and became very reactive as the temps warmed up. Loose, moist avalanches were easily triggered by skiers. These avalanches were at the smallest &quot;knee-twisters&quot; but some grew to size 2.5.
Weak layers from early March, now buried a meter deep, are still reactive in tests. They are most likely to be triggered on solar aspects where sun crusts exist. Smaller avalanches may step down to these layers, resulting in a big avalanche.
A persistent weak layer from late Jan/early Feb remains a serious concern as it continues to be responsible for very large avalanches. This layer is variable in its distribution, is now buried up to 2m deep, is hard to trigger, and harder to predict.
Expect slabs in wind prone areas like below lee ridges at treeline and above and cross-loaded gulley features.&nbsp;
he &quot;drought layer&quot; (Feb 10) has been dormant for over a week now. Warming temperatures and continued wind-loading could 'wake' this layer up.
The new snow fails easily on steep slopes: Manage you group carefully and avoid confined features such as gullies.
Up to 25cm&nbsp; of new snow over the March 26 interface will quickly form a slab with mild temps and the forecast winds. On solar slopes these slabs will be found over a crust and may be particularly touchy.
70 to 110cm of snow is now settling above the early March Crusts. Variable shears persist in these slabs and they are well worth bearing in mind particularly as heating becomes more of a factor in the days and weeks to come.
Watch out for sluffs, as several big ones have been noted today and yesterday - particulary on steep, south facing terrain where a firm suncrust underlies this new snow. Check your exposure and make sure you don't get pushed into any obstacles.
In areas of the park with a weaker snowpack we remain concerned about the Feb 10 layer of facets and surface hoar located in the middle of the snowpack. This layer remains, and caution is advised in specific areas such as the burns in Kootenay Park.
20cm of new snow from earlier this week has bonded poorly to the snow below. It is especially reactive on solar aspects, where it is rapidly destabilized by even a little bit of sun. On lee aspects, soft slabs may exist from windloading by SW winds.
Weak layers from early March, now buried a meter deep, are still reactive in tests. They are most likely to be triggered on solar aspects where sun crusts exist. Smaller avalanches may step down to these layers, resulting in a big avalanche.
A persistent weak layer from late Jan/early Feb remains a serious concern as it continues to be responsible for very large avalanches. This layer is variable in its distribution, is now buried up to 2m deep, is hard to trigger, and harder to predict.
Wind slabs in immediate lee areas have the potential to step down and create large full depth avalanches.
This avalanche condition is quite uncertain and large slopes should be treated with caution. Especially those with recent wind loading or those that face the sun.
Two avalanches were triggered by the sun today.

The &quot;drought layer&quot; (Feb 10) has been dormant for over a week now. Warming temperatures and continued wind-loading could 'wake' this layer up.
Spring sun is gaining in intensity. Expect solar aspects to shed snow during the heat of the day, especially when the skies are clear.
In areas with uneven, shallower or weaker snowpacks, we remain concerned with the Feb 10th midpack layer of crust/facets/surface hoar, and the basal layer. Choose conservative, well supported terrain in these areas.
The recent storm slabs have been slow to bond and remain in the skier triggerable range. Lee aspects in the alpine and treeline elevations are the more likely areas for a slide to propagate. Low elevations may have possible moist sluffs.
more reactive on solar aspects.
The Mar 2nd crust is down around 1.25m. The slab overtop the weak layers down 1-1.5m continues to settle and become more cohesive. The Feb 10 layer down 2m is a major low probability high consequence concern.
Although this problem still remains, triggering still remains possible. As time goes by it will become less likely that people will be able to trigger this layer.
Expect slabs in wind prone areas like below lee ridges at treeline and cross-loaded gulley features in the alpine.
Intermittent breaks in the cloudy weather is consistently producing loose dry sloughing to size 2 as the sun hits recent storm snow.
Although the Feb10 layer (down 60-90cm) has been dormant in the past several days, it remains a concern and has produced several large avalanches this week. Large triggers and shallow areas may still produce avalanches failing at this interface.
We`ve had some incremental loading, 30cm in 3 days. The sun is expected to poke through the clouds today so expect conditions to become more dangerous as the day progresses, specially on the solar aspects if that happens.
Many weak layers are buried within the snowpack in the upper 2m. These are all deep enough to cause large avalanches that will inflict significant damage. Shallow areas and day time warming are most likely to trigger them.

Although the Feb10 layer (down 60-90cm) has been dormant in the past several days, it remains a concern and has produced several large avalanches this week. Large triggers and shallow areas may still produce avalanches failing at this interface.
Several avalanches have been observed deep in the snowpack over the past 24-hours. Avoid shallow areas where the snowpack is weakest. These avalanches are very unpredictable, so choose terrain that avoids steep, rocky slopes.
Over 60 cm of snow has fallen over the past week, and that snow has now settled into a cohesive slab. Caution is advised in all avalanche terrain at treeline and above, in particular one should avoid exposure to avalanches during the heat of the day.
Recent warm temps and wind have contributed to the formation of a soft slab that has failed naturally over the last few days. This slab will become more sensitive to triggering with heating and could be triggered in steep or unsupported terrain.
Daily heating and the sun will create moist snow at low elevations and on solar aspects. Intense periods of radiation will trigger avalanches or cause cornice failures that could trigger avalanches as well.
Strong solar radiation is expected today. Think about getting off sun exposed slope when the crusts that formed overnight break down. Watch for loose avalanches below cliffs as an indication that things are becoming dangerous.
The sun will get deep into the snowpack today and could reawaken one of the many buried weak layers. Avoid slopes where rocks are evident on the surface as they are likely to attract more heat to trigger those layers.
This problem represents a classic low likelihood high consequence situation. Areas that have not previously avalanched will be more susceptible to triggering.
Storm slabs will continue to settle. These slabs will be touchy on Southern aspects in the afternoon.
Recent storm snow has settled into a slab and is touchy on steep, unsupported terrain.
There is a fair bit of uncertainty associated with weak mid-pack layers.&nbsp; Although isolated, there have been numerous natural avalanches in the past 2 days that have failed in the mid-pack or on the ground.&nbsp;
The April sunshine is strong. If it pokes through the clouds today, expect solar aspects to destabilize quickly, especially at lower elevations.
There are numerous sliding layers buried in the upper 1-1.5m of the snowpack. If we see any strong sunshine today, there could be avalanches stepping down to these layers.
The ground level weakness of facets and depth hoar appears to have woken up, and the main avalanche problem right now is occasional large avalanches failing on the ground. Avoid, or carefully select any large steep slopes at treeline or above.
Low elevation areas may see avalanche activity with the day-time warming, especially if the sun pops out.
The upper 1-1.5m of the snowpack has numerous sun and temperature crusts within it. These may become sliding layers with day-time warming and the possibility of a strong April sun popping onto the slopes.
We have seen isolated activity on depth hoar and facets located near the base of the snowpack in thin areas mainly E of the divide. The main problem right now is triggering the occasional large avalanche that fails on the ground. 
This layer may be buried up to a meter below the surface in wind loaded areas. In such areas the upper snowpack may be providing bridging strength. Areas of shallow snowpack particularly adjacent to wind loaded slopes are of greatest concern.
This layer was seen to wake up and produce large avalanche under the influence of strong solar radiation. Convective weather patterns can produce short lived cloud clearances allowing intense solar exposure. Cornice failures can trigger this layer.
Soft slabs were observed in the Alpine by a field team yesterday in the Asulkan drainage, and rising winds this morning will likely create more. Avalanche activity this morning is attributed to this problem.
If the sun comes out or if there is a rapid un-forecast rise in temperature watch out for loose wet avalanches.
Be aware that small avalanches have the ability to trigger larger step down avalanches.
Moderate SW winds in the Icefields are creating windslab conditions along alpine ridgelines cross-loaded features.
Results from this layer were seen on March 31st during a earlier warming event after a prolonged cool period.
Very low confidence in this basal layer of depth hoar as daily avalanches size 2-3 and large whumphs continue to be reported. Mainly a problem on the East side of the Continental Divide or in shallower snowpacks in Kootenay Park.
20cm of new snow with some added wind created some reactive conditions at the higher elevations these past two days. Watch for cracking and more 'slabby' feeling snow as you venture on the upper mountain specially in the lee of ridge features.
Many crusts on solar aspects are buried within the 1m range. At this depth they can be triggered by humans. Avoid shallow snowpack areas where it is most likely to initiate an avalanche on this layer.
Skiers looking for dry snow on the shaded aspects should frequently test the surface layers. A shear persists down about 30 cm with preserved stellar snow flakes and surface hoar. Caution in steep and unsupported terrain is advised.
Daily heating and the sun will create moist snow at low elevations and on solar aspects. As crusts break down avalanches will result. Cornices will also be affected by this heating and could trigger persistent slabs.
With significant heating in the forecast for Monday and Tuesday deep slabs may become active. Large loads such as falling cornices or smaller avalanches could trigger large avalanches on the March crusts or even the February facets.
Southwest winds are creating windslabs along alpine ridgelines and cross-loaded features. Their thickness and interface is variable depending on aspect, elevation, and localized weather influences.
Weak basal facets and depth hoar remain intact and should be on your radar. This deep weakness is difficult to predict and has severe consequences. The snowpack above appears to be bridging the weakness; however, allot of spatial variability exists. 
Thin areas mainly E of the divide are still susceptible to triggering basal layers causing larger avalanches. Big triggers such as cornice failures could be enough load to trigger an avalanche on the ground level
The snow load has steadily increased with winds up high. A surface hoar/crust layer is buried 30-40cm depending on aspect. As this snow becomes moist it will become more susceptible to human triggering.
The upper snowpack consists of many buried crusts on solar aspects. Triggering these layers is most likely from slopes where the snowpack is shallow and/or if there is strong solar radiation even if this is for brief moments.
Windslabs have developed along ridgelines and crossloaded features. Their thickness and interface is variable depending on aspect, elevation, and localized weather influences. It may be present on S aspects over slippery sun crust. Evaluate for this.
Weak basal facets should be on your radar. It is difficult to predict and would have severe consequences if triggered. Allot of spatial variability exists. Field team reports large tree shaking whumph Sunday, in the trees, E aspect, at 1800m.&nbsp;
Thin areas mainly E of the divide are still susceptible to triggering basal layers causing larger avalanches. Big triggers such as cornice failures could be enough load to trigger an avalanche on the ground level.
As freezing levels rise things will become more unstable particularly in steeper terrain and at lower elevations. Snow that is very heavy and creates pin wheels is an indicator that snow stability is decreasing.
We've had enough snow in the past few days to warrant some caution up high. Winds have been steady and combined with rising temperatures things will slab up a some more.
The deeper instabilities that exist in our snowpack can reawaken with the increase in temperatures or added weight of snow/rain. Avoid those shallow snowpack areas where triggering these layers is most likely.
Skiers looking for dry snow on shaded aspects should frequently test the surface layers.&nbsp; A shear persists down about 30 cm&nbsp; with preserved stellar snow flakes and surface hoar. Caution in steep and unsupported terrain is advised.
Daily heating and the sun will create moist snow at low elevations and on solar aspects. Intense periods of radiation will trigger avalanches or cause cornice failures that could trigger avalanches as well.
Although unlikely, a large load such as a cornice failure or another avalanche could trigger all of the snow above these strong crusts. Significant and sustained heating or rain may also allow these slabs to become active such as is forecast Monday.
Windslabs have developed along ridgelines and crossloaded features. Their thickness and interface is variable depending on aspect, elevation, and localized weather influences. Incoming winds and snow Tuesday afternoon will add to this condition.
The deep nature of this weakness is difficult to predict and would have severe consequences if triggered. A lot of spatial variability exists. Field team reports large tree shaking whumph Sunday, E aspect, at 1800m.
">Daily heating and the sun will create moist snow at low elevations and on solar aspects. As crusts break down Loose Moist or even Wet Slab avalanches will result. Cornices will also be affected by this heating and could trigger persistent slabs.

Large loads such as falling cornices or smaller avalanches could trigger large avalanches on the March crusts or even the February facets.
With warming temperatures we expect to see an increase in avalanche activity on our deep facet layers especially in thinner snowpack areas or in places where a cornice fall could act as a large trigger. Minimize exposure to large slopes.
Moist surface sluffing and small wet slabs are likely on all aspects and elevations as freezing levels climb on Tuesday.  Stick to mellow terrain as even a small wet slide can be very powerful.
With high freezing levels, snow is particularly unstable on steeper terrain and at lower elevations. This heavy snow will pinwheel down the mountain, gathering mass, and is a clear indicator of snow stability decreasing.
The recent storm snow has not fully bonded to the underlying crust and surface hoar layer. Combined with the warm temp's, it has become a touchy surface slab that is reacting in higher elevation lee areas.
We may see the deeper instabilities reawaken with the warm temperatures, and possibly rain, moving into the snowpack. Try to avoid shallow, thin areas where a person could trigger a deeper weakness.
The warmer temperatures have the potential to wake this layer up, as demonstrated today on Cascade Waterfall (size 3).
Low elevation south aspects will be particularly susceptible to loose wet avalanches. This problem will be most active in the warm afternoons.
With cooling temperatures this condition will stabilize. Rain and solar exposure will increase the danger. Weather conditions will be variable across the region. Snowballing and pin wheels should be regarded as signs of deteriorating conditions.
Continued wind loading and warming temperatures have increased the triggering sensitivity of this weakness. Strong SW winds on Tuesday were present across the region but most noticeable in the Columbia Icefields area
Strong SW winds on Tuesday have created slab conditions. SE aspects where buried sun crusts may provide a sliding surface should be approached with caution. Thin slabs will likely step down to the basal weaknesses near ground producing large slides.
Be cautious of lower elevation areas that have no crust formation from overnight. Loose avalanches are possible there.
High to extreme winds in the last 24 hours have formed wind slabs in exposed Alpine and Treeline areas where the snow was still soft and dry. Pockets of good dry snow may be found in protected North aspect areas above 2400m.
Be aware that step down avalanches are possible if storm slabs or wind slabs are triggered in wind loaded areas.
Daytime warming in thinner snowpack areas or larger triggers such as cornices may trigger this weakness. Thin rocky snowpack areas may also be susceptible to skier triggering.
Most avalanches regardless of initial form are stepping down to ground. These are most common from shallow snowpack areas where there is little bridging strength in the midpack and the thermal energy is greatest. Rocky areas are also dicey.
Strong South and Westerly winds are transporting the 10-15cm of new snow from the 8th. Rain fell below 1,800m. Field tests at 2,300m produced an easy shear above an old sun crust on the 9th. At lower elevations the slab is less well developed.
There may be lingering surface slabs at alpine and tree-line elevations, due to the strong winds accompanying the last snowfall.
If the sun comes out for prolonged periods today, we will likely see a rapid deterioration of the surface crusts. Start early if you are exposed to solar aspects, especially at lower elevations.
The large size 3.5 from Moccasin Flats 36 hours ago shows the persistent slabs have not gone away. Larger triggers, like cornices or surface avalanches, may step down to deeper layers.
Most observed avalanches in the past week are stepping down to this layer. Frequently observed between 2200-2400m and triggered by  wind loading, cornice falls of solar exposure. Most common in shallow areas or near rock outcrops.
Strong to extreme southerly winds continue to form slabs dating from early April. Slab activity stepping to ground quickly. Buried sun crust can present a sliding layer as seen at 2300m near Marmot. Sheltered snow can be found at treeline and below.
Although conditions are improving, it is still a good idea to avoid large, steep (&gt;35 degree) slopes in areas where the total snowpack depth is &lt;200cm. Use your probe and to check for snowpack depth and strength.
With poor freezes the last few nights and clear days, solar heating has allowed for widespread activity. Expect this activity to dissipate with cooling and clouds but to resume as the sun returns.
West winds continue to transport snow at treeline and above on shaded aspects. Expect to find slabs to increase in their development as you ascend into the alpine
The cloudy skies overnight prevented a decent crust development. Expect lower elevation snow surfaces to be soft, with temp's getting close to isothermal, creating an unstable snowpack.
The 10-15cm of snow from a few days ago was redistributed by strong winds, creating windslabs in exposed alpine and tree-line locations.
Without a good refreeze, there is less structure to the snowpack to prevent it from stepping down into the lower persistent weaknesses. The large size 3.5 from Moccasin Flats 2 days ago illustrates the potential destructive force lingering out there.
Colder weather will add a little more stability to the snowpack. It is still too early to move out onto big alpine lines.
Most observed avalanches in the past week have stepped down to this layer. Triggers include: wind loading, cornice fall and solar exposure. Most commonly triggered from shallow areas or near rock outcrops.
Gusty moderate SW winds continue to form slabs dating from early April. Sheltered snow does exist at treeline and below.
Warm temperatures and solar inputs will deteriorate snow stability today as avalanche hazard rises in the afternoon.  Watch for terrain above you getting headed through out the day and use safe travel techniques to manage your group.
New snow in the past weak is possible to skier-trigger.  Watch for hard, wind-deposited snow on lee features in the alpine.  Storm slabs failing on crusts is possible at lower elevations.
Weak layers buried deeply in the snowpack are still releasing naturally and producing avalanches up to size 3.5.  Warm temperatures and solar inputs elevate this hazard. Large, heavy triggers like cornice falls could trigger a large avalanche.
Triggering this layer is most likely during warm periods and from thin rocky locations. Large triggers such as cornices may also trigger this deep weakness. This hazard will gradually increase as temperatures warm up over the next few days.
With tomorrows clear skies and sunshine we will likely see loose wet slides on steep S aspects in the afternoon.  Cornice failures are also possible as things warm up. Plan to finish your trips by early afternoon.
Fat windslabs are present below ridgelines and on cross-loaded features. The bond between these slabs and the snow beneath is uncertain, however, warm temps and solar exposure will weaken them.
Large triggers such as cornice fall or smaller slab/loose wet avalanches may trigger this weakness. Skier could trigger from shallow areas or near rock outcrops.
A melt freeze crust is present with wet to moist snow beneath. The crust will deteriorate by mid afternoon and and avalanches are likely after this time. Steep solar aspects have the greatest likelihood.
Intense solar inputs will weaken last nights refreeze quickly and a loose wet cycle will likely start in the early afternoon.
Slopes that have been baking in the sun can fail as a slab on crusts and on higher alpine elevations on North lee aspects.
The Mar 2nd crust and Feb 10 layer can be triggered by heavy loads such as cornices or loose wet slides, a likely scenario with the forecast strong solar inputs.
The big question for this avalanche problem is heat. Under current cool conditions it is nearly dormant. However, when we receive the first real blast of heat...pay attention.
Low elevation solar aspects are the main features to be aware of. Of course, if it remains cool little activity should be expected, add heat and south slopes could come alive with avalanche activity.
Windslabs are present below ridgelines and on cross-loaded features.  No avalanche activity has been observed on these slabs but field teams have not tested bonding.
Later in the afternoon, loose moist/wet avalanches may start to come down if the sun is out and there is no cloud cover.
If the sun has been baking slopes, there is the possibility of a slab avalanche failing on buried crusts. In the alpine slab avalanches could be triggered on lee North apects.
The Feb 10 layer is the monster that can be triggered by heavy loads. It is still a 3-5cm thick sandwich complex layer of SH, FC and crusts.
This problem seems to have calmed down in the last week, but we remained concerned and expect&nbsp; to see more of these avalanches when the temperatures warm up again.
On Tuesday expect this problem only on lower elevation, sun exposed places. Watch out in steep cliffy areas or steep forest in the afternoon.
Snow flurries on Tuesday will add to the danger near ridge tops and into the alpine. Good skiing will likely exist in sheltered locations at lower elevations.
Even short bursts of solar heating can rapidly affect the snow this time of the year. With mild temperatures in the forecast, watch for rain to affect the snow at lower elevations.
Isolated and thin windslabs have been built in open features and can be found poorly bonded to crusts. Watch for these to grow or to become hidden with incoming snow.
Low elevation areas are relying on a good overnight freeze to keep the snowpack together. There was not a strong freeze last night, so expect the surface crust to break down with light rain and the occasional glimpse of strong April sunshine.
Thin, variable slab is present in the alpine and tree-line. It appears to be bonding with the underlying interface, but some pockets in lee features may surprise a person.
Deeper persistent layers will require a large trigger to initiate, or a couple of people hitting a thin, weak spot in the snowpack.&nbsp;
Although the forecast is calling for cooler, cloudier conditions, if the sun comes out, it will be strong and can destabilize the snow quickly. Also, be careful at lower elevations if it is raining.
This condition is most prevalent in the alpine near ridges and open bowl features. Near treeline the slabs are most threatening when sitting over buried sun crust on southerly facing slopes.
2 weak layers within our snowpack, down ~1m and ~1.2m that are producing tests results to be concerned about. Whoomphing and cracking may not be as prevalent due to the depth of the layer but if triggered the slab is likely to propagate.
The primary problem in the snowpack is the interface between the recent storm snow and the November 6th and 24th facet/crust interfaces. This problem is the culprit for the vast majority of the avalanches in the past week. Watch for remote triggers.
The wind affect will be encountered above treeline and above in wind exposed terrain.
Storm snow will continue to be redistributed by predominantly NW winds at ridge tops in the high alpine . Storm slab could become more active if warmer temps and or higher winds develop.
Dry loose snow avalanches are still possible in steep rocky and unsupported terrain.
Persistent weak layers buried down ~1m and ~1.3m are cause for concern. As temperatures rise the likelihood of triggering will increase and they are capable of producing very large avalanches. Be especially cautious on planar open slopes.&nbsp; </span></p><p class="p_CC664AAA"><span class="s_AA239A9B">

These deep persistent slabs at tree line and sheltered alpine slopes may be triggered from shallow areas within the snowpack.
Approach loaded, cross-loaded and re-loaded lee features with caution.
This SH layer now sits below 20-30cm of new snow. A storm slab is developing at higher elevations and wind-exposed areas. These slabs will bond poorly to the SH interface. Avalanches on this layer may run farther than expected, easily entrain snow.

Light snowfall and moderate SW through into Sunday will lead to the development of wind slabs on sheltered aspects. Any significant accumulations that overly existing surface hoar crystals could produce touchy conditions in a few isolated areas.
The interface between the strong mid-pack and weaker basal facets is most susceptible to human triggering from shallow rocky areas.
A storm slab is developing, 25 to 30cm thick, at higher elevations and wind-exposed areas. These slabs will bond poorly to the surface hoar layer which it sits on. Avalanches on this layer may run farther than expected and easily entrain snow.

Wind loading producing wind slabs on lee and cross loaded features predominately below alpine ridge lines.
This layer can be found above 1900m and can be triggered from shallow areas in the snowpack.  A strong rain crust exists below tree line up to 1900m.

A 50cm slab sits over a very obvious surface hoar layer that reacted to human triggering yesterday. Sensitivity varies depending on drainage and elevation but the layer was observed to be almost everywhere and is a very real threat to riders.
The new snow load continues to slowly build and this could reawaken the Nov 9 layer at the bottom of the snowpack. Shallow avalanches running on the surface hoar can also trigger this layer. This will be even more of a concern in the coming days.

This weak layer exists below a strong mid-pack at treeline and sub-alpine elevations. Field teams are still experiencing the occasional whumph from these weak layers collapsing.
Test the shear found on the weak snow above the crust frequently. Although clean shears found on the facets alone are serious, the isolated areas that hold surface hoar should be treated with even more respect. More snow may make this more touchy.

Wind loading producing slabs on lee and cross loaded features at all elevations. Field teams today experienced cracking and whumphing in the new wind slab.
This weak layer exists below a strong mid-pack at treeline and sub-alpine elevations. Field teams are still experiencing the occasional whumph from this layer. Surface slides or cornice collapse could trigger this deep persistent weakness.
A 50cm slab sits over the December 17th surface hoar layer that reacted to human triggering yesterday. Sensitivity varies depending on drainage and elevation but the layer was observed to be almost everywhere.&nbsp; This layer is a real threat to riders.

The weak snow above the crust is new primed with a big enough slab for there to be serious consequences of triggering an avalanche. Isolated areas that hold surface hoar should be treated with even more respect.
The storm snow may now be hiding wind slabs in the lee areas of exposed features above treeline. New slabs will build with the 20-25cm of storm snow now available for transport. These will become larger and more easily triggered as the wind picks up.
Wind loading producing&nbsp; soft slabs on lee features at and above treeline. A field team on the 24th found a generally stable snowpack with hard and moderate shears in the upper snowpack at&nbsp; alpine elevations. Good skiing in sheltered spots.

Rider triggered and remote avalanches are happening daily on a widespread surface hoar layer down ~50cm. The overlying slab has gained enough strength to propagate widely which means bigger consequences. This problem will persist for a while. 
Storm slab avalanches may step down to deeper layers, including the the Nov 9 layer at the bottom of the snowpack. The resulting avalanche would be very large.
The weak snow above the crust is now primed with a big enough slab for there to be serious consequences. In the alpine this problem will likely be limited to N and E aspects but at treeline it is widespread. Use extra care in open, sheltered terrain.
Remember that previous West Winds had a strong effect on the current distribution of snowpack: fragile cornices and buried windslabs will complicate the picture and limit terrain choice as travelers look to avoid the persistent slabs
