Renew your respect for this layer as the new loading ramps up. We are unsure of how it will handle any additional load. Alpine wind loading and cornice failure is particularly concerning.
Expect heavy sluffing in steep terrain on all aspects if the forecasted storm comes true.
Rain at lower elevations has led to a gradual break down of surface crusts and has contributed to wet snow sluffing and gathering mass in steep terrain. Forecast sunshine on Tuesday could shift the problem to higher elevations.

Soft slabs are beginning to build along alpine ridgelines with moderate SW winds.  Otherwise, the storm slabs remain soft in nature as winds have yet to firm them up. Soft slab conditions also exist on gully sidewalls and some large alpine slopes.
Strong sunshine will trigger loose avalanches and make skier triggering more likely on solar aspects today. Solar triggered avalanches may step down to deeper layers, triggering large slab avalanches.
The surface hoar/crust layer from February is becoming less reactive; a function of it now being 1-1.5m deep and having avalanched in many areas. It is most likely to be triggered on solar aspects or by heavy triggers, resulting in large avalanches.
Expect loose wet avalanches to occur with daytime heating.  Caution on or below any steep solar aspects as temperatures warm up during the day.

The surface hoar/crust layer from February is most likely to be triggered on solar aspects from shallow areas or from large triggers such as cornice falls resulting in large avalanches.
With more snow the potential for loose dry avalanches in steep terrain will increase.  Manage your sluffs carefully especially in confined terrain.  With warming temperatures these may quickly turn into more serious storm slabs.
The surface hoar/crust layer from February is most likely to be triggered on solar aspects from shallow areas or from large triggers such as cornice falls resulting in large avalanches.
New storm slabs will be sitting on a variety of surfaces, from colder powder snow or sun crust at higher elevations depending on aspect, to rain crust 1800m and below. 
At higher elevations, expect all gully features and exposed terrain to slough with the increased winds and new snow.  Steep terrain below treeline may slough far and fast.
Warm temperatures at lower elevations will create moist point release avalanches from steep terrain.
A storm overnight has brought 25-30 cm of new snow with strong winds and rising temperatures. This has formed avalanche conditions.
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.
Dense, very touchy storm slabs developed overnight with the new snow and warm temperatures. More snow is forecasted for the next 24 hours.
Rain to 1900m has created unstable conditions below tree-line. Travel is not recommended.
Warm temperatures and rain at lower elevations are creating moist point release avalanches from steep terrain. Solar radiation will rapidly destabilize the snowpack in the valley bottom and near treeline.
A storm that started on Wednesday has brought 30-45cm of high density new snow with strong winds and rising temperatures. This has formed avalanche conditions.
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.

Rain to 1900m has created unstable conditions below tree-line. Travel is not recommended until the temperatures cool down.
Currently a cycle of loose wet avalanches is occurring at all elevations in steep terrain.  This should decrease as temperatures cool by Saturday and the snowpack tightens up.  Until things cool down travel in avalanche terrain is not recommended.
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.

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.
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.
Cooler temperatures will start to take some moisture out of the snow for Sunday, but will take a couple of clear nights to freeze.  Thin, steep, gullied terrain will be the most susceptible to triggering.
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. 
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.
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. 
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.
In shallower areas east of the divide deep slabs have been observed failing on the lower facetted snowpack

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.
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.
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.
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.
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.
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.
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.

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.
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.
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. 
As the daytime temperatures rise we may see loose wet avalanches on steep solar aspects especially if dark objects like rocks and trees are present on the slopes.  Travel early on steep solar aspects and pay close attention to daytime temperatures.

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.
Cooling temperatures over the next 3 days will reduce magnitude, frequency and distribution of of these events. Pay close attention to the increasing air temperature and met freeze crust thickness. Once gone you should head for safe slopes.

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.
Cooling temperatures over the next 3 days will reduce magnitude, frequency and distribution of these events. Pay close attention to the increasing air temperature and met freeze crust thickness. When crusts are gone you should head for safer slopes.
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.

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.
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.
If sunny, pay close attention to the increasing air temperature and the thickness of the melt freeze crust. Rain events will increase the elevation, range and aspect of this hazard.
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.
This seems less of a concern the next couple of days with cooler temperatures but still a potential problem at low elevations. Be attentive to the air temperature and the thickness of the melt freeze crust particularly as the day progresses.
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.

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.
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
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.
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.
4cm thick rain crust found below tree line and up to 2700ms. No new avalanches have been observed on this layer.
Winds are expected to increase today, expect soft slabs at higher elevations that will be easily triggered by riders as sits is over a surface hoar layer. Lower down sluffs can gain mass and have larger consequences than expected.
Our latest surface hoar/crust layer is down under 30 to 40cm of storm snow. Consequences of triggering will increase as the slab strengthens over time.
Only on very steep slopes will there still be any sluffing.
Very cold temperatures from the past few days have made the upper snowpack unconsolidated and riders should expect fast sluffing on steep slopes in areas that were not wind affected.
It would be possible to trigger an avalanche in open, unanchored lee terrain. Slabs will continue to develop through the week.
25cm of new snow sits over a newly buried surface hoar layer down low and wind slabs up high. Riders should&nbsp; expect sluffing in steep terrain that could reach down into deeper unconsolidated layers and gain mass.
The new, low density snow overlies a loose, facetted upper snowpack. Skiers and riders should expect fast sluffing in steeper terrain, which may gain mass if it entrains the underlying facets.
Surface snow has been seen to be sluffing fast and entraining the underlying loose facets. Heads-up in gullies and above cliffs.
Slabs are forming in over 40cm of storm snow.  Use caution in terrain over 30 degrees. Rider triggering is possible.  Fast sluffing is likely and will pick up large amounts of snow.  Avoid exposure to terrain traps.
Soft slabs are forming in over 50 cm of storm snow.  Use caution in terrain over 30 degrees. Small avalanches could trigger deeper instabilities.  Fast sluffing is likely and will pick up large amounts of snow.  Avoid exposure to terrain traps.
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.
Over 50cm of storm snow has created soft slabs.  Use caution in terrain over 30 degrees.  Small avalanches could trigger deeper instabilities.
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.
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.
55-60cm of storm snow in the past week with mild temperatures have created ideal slab conditions.
This weeks storm deposited 80cm of snow under ideal slab forming conditions. This slab sits on a weaker surface that may be reactive to skiers and riders, and the slab is deep enough to produce large avalanches.
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.
Loose snow can quickly pick up speed and mass in gullied terrain.
The recent snow has tightened into a slab. It sits on various weak crystals, like surface hoar and facets, that can be triggered by people. These avalanches may step down to deeper surface hoar layers, resulting in large avalanches.
There may be a number of windslabs on North and East slopes that have built during the wind events of the last week.
The crusts near the bottom of the snowpack have been weakening, especially on cooler North aspects.
A weak layer is buried down around 80 cm.&nbsp; If triggered, a large, high consequence avalanche will result. Carefully evaluate big terrain features by digging and testing adjacent, safe slopes.
A weak layer is buried down 60 to 90 cm. If triggered, a large high consequence avalanche will result. Carefully evaluate big terrain features by digging and testing adjacent, safe slopes.
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.
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.
40cm of recent storm snow is settling. Within this slab are layers of large, weak snowflakes that may be triggered by skiers/riders.
The interface between the December snow and the facetted November snow, down ~80cm is the biggest concern. Although this interface is becoming less likely to trigger it is possible, or smaller avalanches may step down to this layer.
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.
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.
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.
Recent strong SW winds have built windslabs at ridgelines and gully features. Warm temperatures have likely helped strengthen these slabs but triggering is still a possibility.
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.
60cm of storm snow is likely to be triggered by riders. Use caution in steep, unsupported terrain.
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.
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.
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.
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.
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 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.
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.
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 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.
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.
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.

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!

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.
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.

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. 
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.
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.
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 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.
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.
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.
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.
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.
Full depth avalanches continue to be seen daily on this layer. We expect another natural avalanche cycle on this layer on sunny aspects with the forecasted temperatures and sun. Even a cornice release in the heat could trigger a large 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.
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
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.
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.
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.
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.
Natural activity has tapered off on this layer, but it is still possible to trigger big avalanches in shallow locations.
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.
Low likelihood, high consequence. This means the chance of triggering is decreasing, however, if you do, it will be a big slide.
Natural activity has tapered off on this layer, but it is still possible to trigger big avalanches in shallow locations.
Thin soft slabs now hide either hard windslab or suncrust. They may not be bonded well, and could be a concern in steep terrain where a slip/fall has a significant consequence (ie cliffs).
Natural activity has tapered off on this layer, but it is still possible to trigger big avalanches in shallow locations.
Thin areas will have the biggest potential for triggering the basal depth hoar/crust layer. Caution is advised in steep, planar features. Avalanches will be full depth with large consequences.
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.
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.
Natural activity has tapered off on this layer, but it is still possible to trigger big avalanches in shallow locations.
Be aware of solar warming which could trigger a slide on this layer which in turn may step down and release the basal weakness.
A supportive slab over a shallow spot in the snowpack could provide the energy for a small avalanche to step down into this layer.
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.
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.
Be conservative with your terrain selection and assess steep or unsupported planer slopes carefully where the snowpack may be thin. In these areas it may be possible to trigger the weak faceted area created early in the winter.
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.
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.
30 cm above the ground, this weak snow is a serious concern. Travelers should carefully consider snowpack depth, terrain shape, and slope angle. Use your probe to confirm depths when you are uncertain.
The recent snow fails easily in steep terrain up to 25cm deep. Expect this to dissipate as the wind moves in.

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
This layer is still touchy. Expect it to be most reactive on south aspects near tree-line. Typically, it will be about 40cm thick.

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.
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.
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.
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.
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.
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.
A poor bond still exists between the storm snow and the Feb 10 interface. This interface is reactive to skier triggering. (see avalanche details)
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.
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.
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.
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.

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.

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.

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.
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.
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 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.
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.
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.
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.
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.
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.

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. 
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.
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.
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.
This problem will start to become a regular occurrence as the intensity of the sun increases and valley bottom temperatures climb.

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.
This problem will start to become a regular occurrence as the intensity of the sun increases and valley bottom temperatures climb.
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.
Expect the avalanche danger on sheltered solar aspects to be suspect during the heat of the day.&nbsp;
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.
Watch locally for daytime warming in steep, solar features.
Expect the avalanche danger on sheltered solar aspects to be suspect during the heat of the day.
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
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.
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.
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'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.
Overnight and continued rain below 1100m will weaken the upper snowpack. These conditions are dangerous in any steep terrain even if heavily forested. These avalanches will be slow moving but very heavy and difficult to manoeuvre out of.
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.
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.
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.
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.
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.
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.
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.
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
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.
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.
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.
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.
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 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.
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.
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.
Two avalanches were triggered by the sun today.

A weak layer down 20-30 cm is still reactive to skier-triggering. Use caution on unsupported features and convex terrain. Watch for changing conditions as temperatures warm up today and surface crusts deteriorate.
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.
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.
Intermittent breaks in the cloudy weather is consistently producing loose dry sloughing to size 2 as the sun hits recent storm snow.
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.
Intermittent breaks in the cloudy weather is consistently producing loose slides to size 2 as the sun hits recent storm snow.
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.
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.
This problem represents a classic low likelihood high consequence situation. Areas that have not previously avalanched will be more susceptible to triggering.
The April sunshine is strong. If it pokes through the clouds today, expect solar aspects to destabilize quickly, especially at lower elevations.
Low elevation areas may see avalanche activity with the day-time warming, especially if the sun pops out.
If the sun comes out or if there is a rapid un-forecast rise in temperature watch out for loose wet avalanches.
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.
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.

Large loads such as falling cornices or smaller avalanches could trigger large avalanches on the March crusts or even the February facets.
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.
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.
Be cautious of lower elevation areas that have no crust formation from overnight. Loose avalanches are possible there.
Be aware that step down avalanches are possible if storm slabs or wind slabs are triggered in wind loaded areas.
Solar effect and day warming will destabilize the snowpack on all slopes in the valley bottom. The danger will increase as it does. Travel below 1700m will be ugly. With increasing elevation and slopes that don't face south this effect will diminish.
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.
Cool temperatures are suppressing this building instability. Localized sunny breaks will quickly reverse this big picture qualifier rapidly increasing the danger on the local radiated slope. Snowballing and pinwheels are good warning signs.
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.
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.
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.
A melt freeze crust will form overnight however it will&nbsp; deteriorate rapidly with prolonged solar exposure.
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.
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.
A melt freeze crust is present with wet snow beneath. The crust will deteriorate by mid afternoon. Steep solar aspects have the greatest likelihood. 
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.
On Tuesday expect this problem only on lower elevation, sun exposed places. Watch out in steep cliffy areas or steep forest in the afternoon.
The snowpack is warming and has the potential to rapidly destabilize with solar exposure or rain. At these times the crust, found near the surface, will melt releasing the moist and wet snow beneath. The danger will increase  rapidly as it does.
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.
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.
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.
Cool temperatures are limiting the extent of this problem. This can change rapidly with solar radiation particularly near rock alcoves that act like solariums. Watch for signs of snow melting during the day. These events will likely scrub to ground.
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.
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.

These slabs taper radically with elevation and are sitting on a thick crust. Large slides resulted from failures in the recent storm snow over the crust that extends to around 2300m. These slabs may become easier to trigger with the expected heating.
Rapid warming with mixed rain and snow is leading to an increasing avalanche hazard.&nbsp; Recent storm snow may be sitting on good sliding surfaces such as surface hoar and crust.
Trigger points for the persistent weak layers buried down ~1m and ~1.3m include steep alpine terrain, thin areas, and unsupported open slopes.&nbsp; Once initiated avalanches triggered in the storm snow may step down to the deep persistent weak layers.</span></p><p class="p_CC664AAA"><span class="s_AA239A9B">

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.
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.

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. 
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.

The Dec17th surface hoar is still reactive, with most events at treeline. A size 2 skier-controlled avalanche released on this layer yesterday. Buried surface hoar requires careful decision making, especially as more new snow continues to fall.
Although powdery in most places, 20-25cm of new snow is gaining cohesion. This layer has concealed recently formed wind slabs in exposed ares. Riders may be surprised by this layer, as these avalanches have the potential to trigger deeper layers.
The Dec17th surface hoar is still reactive, particularly at treeline. As new snow continues to fall the consequences of an avalanche on this layer increase, careful decision making is still necessary.
30 cm of low density storm snow is likely to move fast in sufficiently steep terrain. Be aware of your sluff as it could pick up mass and push you around.

The Dec 18 layer of surface hoar and crust is now buried 50-70 cm and primed for human triggering.  Avoid any areas where avalanches can start.
Facets and isolated surface hoar above the Dec 13 crust remain the feature to watch in the snowpack. New load from storms or wind transport will make this more sensitive to triggering especially when combined with warm temperatures Wednesday.
The snow from the turbulent storm is forming a 30 to 40 cm soft slab at all elevations that fails very easily in tests over the cold low density snow from the weekend. Expect more development of these slabs at higher elevations with more wind effect.

Sluffing can be expected in steeper features at and below treeline in non-wind affected locations.  keep an eye out for people traveling below you in open terrain and stay out of terrain traps where sluffs can have larger consequences.
The storm slab should be settling and stiffening with the warming temperatures.  The question is the bond to the old snow surface of colder recrystalized snow.  We currently think this interface is weak and ripe for triggering.

Watch for rain in lower elevations
A widespread loose wet natural avalanche cycle was observed yesterday afternoon. A poor overnight re-freeze combined with ongoing warm temperatures and new precipitation will continue to destabilize the upper snowpack.
Large cornices or surface avalanches are the likely trigger for this slumbering giant.
New slabs sitting on a newly formed crust can be found at all elevations but are much more significant at the upper limits of treeline and the alpine. These will be more reactive in steep or unsupported terrain and may be ripe in many start zones.
As temperatures increase this week watch for moist snow to develop at lower elevations where most of the snowpack has yet to refreeze. If the sun comes out this will happen quickly on solar slopes.
Watch for moist snow and loose avalanches originating from cliffs as indications of instability. At lower elevations you can probe with your pole to see how thick the crust is and determine whether it is breaking down with day time warming.

The amount of overnight freeze and solar input will dictate how big of a concern this problem is on Tuesday. Pay attention to how quickly the day is warming up.
Continued warm precipitation has been enough to begin to overload the various persistent instabilities in our snowpack. A series of weak layers in the top 1.5m of snowpack should be considered triggerable by back country riders.
Widespread loose wet avalanches have been occurring in the highway corridor and should be expected in the back country at and below treeline.
Heavy rain at lower elevations has soaked any remaining snow left at below treeline elevations, thereby increasing the risk of loose wet slides. The cooling trend should help 'tighten' up the snow at this elevation over the next few days.
20cm of new snow has added to the growing storm slabs at higher elevations. Strong SW'ly winds have magnified loading creating deeper, and touchier, pockets in lee areas. The storm slabs may be more reactive where they bond poorly to crusts below.
Up to 60cm of new snow exists at higher elevations. This new storm snow will get it's first &quot;kiss from the sun&quot; today, which often triggers avalanches. The storm slabs may be more reactive where they bond poorly to crusts below.
Small amounts of snow above the crusts will fail easily with solar heating.
Strong solar radiation is forecast for today. Once the overnight crust breaks down expect more avalanche activity on solar aspects.
The new snow is likely to fail easily in very steep terrain naturally however travelers will experience sluffing in steep terrain as they travel through. Manage your group carefully to prevent being caught by these sluffs especially above cliffs.
As the sun comes out on Tuesday expect moist snow to develop and fail naturally first on solar slopes and then on lower elevation shaded slopes. This should be more serious on Thursday with clear skies and a higher freezing level expected.

The snowpack is generally weak throughout the BYK region, except in areas of deeper (thus stronger) snow. Avoid most steep terrain, and watch for signs of instability such as whumping and cracking. Things are improving, but slowly.
~50cm of snow is settling into a soft slab and sits on a crust on solar aspects and surface hoar. If triggered it will likely run far &amp; fast especially with the crust as a bed surface. Expect it to sluff easily in areas where it hasn't formed a slab.
The snowpack can still be weak in the BYK region, except in areas of deeper (thus stronger) snow. Avoid steep unsupported terrain, and watch for signs of instability such as whumphing and cracking. The snowpack still slowly improving.

Clear skies and high solar input will cause natural avalanches on solar aspects Saturday. These can provide enough mass to trigger persistent and deep persistent weak layers (listed below) causing larger avalanches.
Expect loose wet avalanches on solar aspects as the day heats up. These may trigger persistent slabs where buried crusts exist.
Expect the new snow to become less stable on solar aspects with daytime heating.
Buried crusts are creating persistent instabilities on solar aspects.  Storm snow sits on a crust down 30-50cm. February crust is down 80-120cm and still has surface hoar crystals on top in some places. Locate and test these layers before committing.
Intense spring sun coupled with rising freezing levels can trigger loose wet avalanches with the potential to run far. This is a classic &quot;step-down&quot; scenario where a small releases could trigger storm slabs and buried persistent weak layers.
A mild inversion Sunday with a chance of rain and a poor recovery into Monday could cause surface events. These could provide enough mass to trigger persistent and deep persistent weak layers (listed below) causing larger avalanches.
Expect loose wet avalanches at low elevations and on solar aspects with inversion conditions and a poor overnight recovery into Monday with the chance of rain. Loose wet avalanches may trigger persistent slabs where buried crusts exist.

Any steep slopes should be avoided later in the day when the crust on top of the snowpack breaks down due to daytime heating. Crusts remained intact on Thursday to 1600m. Start early and finish early.
Watch for a cycle of loose wet avalanches in the new snow. Size will be dependant on snowfall amount. On Friday this will mainly be on sunny slopes; heat on Saturday and Sunday may spread this problem to higher/shadier terrain.
A strong surface crust exists, and with good timing spring &quot;corn&quot; skiing can be had when the surface starts to break down. However, if the crust has completely broken down loose wet avalanches will be easy to trigger and can entrain significant mass.
As the snowpack warms and weakens during the day wet slab avalanche are more likely. Large and destructive wet slab avalanches have been observed recently. As freezing levels rise over the weekend more avalanche activity is expected.

A crust buried up to 1m deep may become increasingly reactive over the weekend and be hard to predict. Test results show variability: in some areas it is unreactive and in others it may be triggered by light loads (you!) and produce large avalanches.
Forecast snow and wind might make a crust buried up to 1m deep more reactive and unpredictable. Test results show variability: in some areas it is unreactive and in others it may be triggered by light loads (you!) and produce large avalanches.
We are expecting up to 30cm of snow by Sunday. This will add to ~20cm of powder sitting on the surface. Expect sluffing and loose avalanches to be triggered when skiing steep slopes. The loose snow also hides tree wells; buddy up!
Moderate winds and significant snowfall should be creating sensitive storm slabs in the alpine and open areas at treeline.
20cm of storm snow so far with another 10cm expected by Sunday. This is in addition to the 20cm of soft snow on the old snow surface. Loose snow avalanches can be expected in steeper terrain.
Storm snow loading on top of the persistent slab/Nov crust could make this deep slab more reactive. Field tests so far show variability with areas that are unreactive and others where light loads may trigger slides on this layer.
Newly formed storm slabs should be treated as susceptible to human triggering. Once triggered it may overload the Nov 13 crust layer resulting in large avalanches.
Upwards of 60cm of loose dry snow has fallen. Sluff management will be essential for safe travel. Watch for others above and below you. Sluffs may overload storm and windslabs given the right location.
While natural avalanche activity is tapering off, human triggered avalanches are still likely. Our new storm slab sits on previous wind slabs, combined this avalanche problem has the potential to step down to the Nov 13 Crust. </span></p><p class="p_CC664AAA"><span class="s_AA239A9B">
Upwards of 80cm of loose dry snow has fallen. Sluff management will be essential for safe travel. Watch for others above and below you. Sluffs have the potential to push a rider into a tree well or other terrain trap.
Sluffs have the potential to push a rider into a tree well or other terrain traps. With the recent arrival of 80cm of loose dry snow, sluff management will be essential for safe travel. Watch for others above and below you.
This will mainly be a problem on Sunday as wind moves low-density snow around.
This problem is most widespread in the alpine, where new snow totals are highest; but has also been noted in steep ice climbing areas Below Treeline. Skiers, use caution in steep terrain; Climbers, use caution around gullies, and avoid during wind.
Wind slabs are currently a problem in the Alpine in Western Areas, and on all snowy slopes in Eastern areas.&nbsp; Watch for this problem to move to S and W facing slopes if we see moderate NE winds Thursday-Friday.
The low density snow that has made for great skiing lately is being blown to many places. With Extreme winds, watch for Wind Slabs in unusual places. New snowfall on Monday will increase this problem. These may be hidden by more snowfall on Tuesday.
30cm of storm snow is settling over a very weak old surface of facetted  snow. The surface slab will be sensitive to human and natural triggering especially in areas of wind effect as it overloads the weak layer.
Sunday afternoon we were already observing loose dry snow sluffing as the weak old snow surface was overloaded.  Add another 30cm overnight and these slides could entrain enough mass to be an issue for skiers and riders.
48 hours of intense ridgetop transport due to strong SW winds has created new windslabs, reactive to skier traffic. Numerous natural avalanches were observed from a variety of aspects, particularly alpine gulley features and planar NE slopes.
50cm of storm snow with strong gusting winds is sitting over a very weak old surface of facetted snow. Cracking and whumphing was observed yesterday from groups out skiing. With additional snowload and settlement the surface slab will remain touchy
Where the new snow is unconsolidated heavy sloughing is expected. Add another 10cm of new snow today and in steep terrain these slides could entrain enough mass to be an issue for skiers and riders.
72 hours of intense ridgetop transport due to strong SW winds has created windslabs. Numerous natural avalanches were observed from a variety of aspects, particularly alpine gulley features and planar NE slopes.
~80cm of storm snow is settling into a slab. It sits on a weak and reactive layer of facets and spotty surface hoar. Yesterday skiers accidentally triggered a storm slab avalanche, partially burying a member of the group. Human triggering is likely.

Strong winds have created a mosaic of snow depths across the landscape. These slabs will vary greatly in their triggering sensitivity requiring each slope to be carefully evaluated. The only rule of thumb to keep in mind is caution is advised.
Cold temperatures have kept recent storm snow light and powdery, but slab properties are beginning to form. The slab sits on the December 18 facet/ surface hoar down 50-60cm. Stability tests show that the storm slab is reactive to skier loads.
Nearby operations have reported these failing in the middle of the snowpack, and in some cases stepping down to ground. They are most likely to be triggered in thin Rocky areas, which are more widespread in the Eastern areas of the Park.
These are more widespread than usual, existing on most aspects and elevations due to the intensity of previous winds. They will be hard to spot under new snowfall. New Wind Slabs will build with forecast Strong Westerlies on Monday.
Recent storm snow has been slow to form a slab in part due to cold temps. Slab properties are starting to form.  The slab rests on the Dec 18 facet/surface hoar layer down 50-60cm.  Stability tests show that the storm slab is reactive to skier loads.
New snow amounts have slowly piled up, especially in Eastern areas with the influence of an up-slope flow. The weak Dec 19 facets do not provide much support for this snow and once a sluff is initiated in steep terrain, it can run a long distance

The weak, facetted snow from the cold snap in early December is now buried ~70-100cm. The slab over this layer is developing, and as the load on this layer grows it may become increasingly reactive.
In areas sheltered from the wind there is a lot of amazing, low density powder. Expect sluffing when skiing steeper pitches. With all the loose, light snow a small avalanche may pick up mass especially in more confined gully type terrain features.
Up to 30cm of snow fell in the last 24hrs at treeline with another 15-25 expected today &amp; tonight. This new slab has buried a spotty surface hoar layer, that could be lurking. Expect this new load to take some time to stabilize.
50cm storm snow in 48hrs with flurries expected today. The storm snow has buried a spotty surface hoar layer to dig and look for. The new load will take a few days to stabilize.
Nearby areas have seen these failing in the midpack facets in thicker areas and in loose sugary facets near the ground in thinner areas. They are most likely to be triggered in thin rocky areas, with variable snowpack depth.
60+ cm of new snow in the last 72 hours at tree line has created storm slabs most reactive at tree line and in the Alpine. The storm slab also stepped down to the Dec 18th interface yesterday on steep shallow southerly aspects with artillery control.</span></p><p class="p_CC664AAA"><span class="s_AA239A9B">
Since Thursday we have received 60cm+ snow at 1900m elevation which is settling into a slab. Expect the forming slab to be most reactive at and above TL. The storm slab did step down to the Dec 18th interface with artillery and explosive control.
These are touchy, especially to the immediate lee of ridges. Look for these on the opposite side of features from normal. The storm snow will be slow to stabilize, due to cold temperatures. Wind Slab problems may develop on Wednesday.
The weak midpack facet layer is widespread, but highly variable slab thickness and sensitivity makes these hard to evaluate. These are difficult to trigger, but may be large. Rocky, wind-exposed areas are most suspect.
The weak mid-pack facet layer is widespread, but&nbsp; the slab over it is variable. These may be&nbsp; difficult to trigger but&nbsp; are high consequence. Avoid large uniform features, shallow trigger points, and watch for slab properties in the upper snowpack.
The weak facet layer is isolated to thin snowpack areas where the presence of any slab over these crystals would spell concern. Avoid thin snowpack areas, use caution with large uniform features, and consider the potential for shallow trigger points.
Faceting of the surface snow is causing it to lose cohesion and release loose dry avalanches in steep terrain. Particularly concerning for ice-climbers in confined terrain.

The faceted snowpack continues to lose cohesion and release loose dry avalanches from steep terrain. This is concerning for ice-climbers and skiers in confined/exposed terrain.
Facets in the midpack have produced sporadic test results, and loads in thin Alpine areas could trigger Deep Persistent Slabs on a Depth Hoar/Crust combo near the bottom of the snowpack. Near-zero temps may increase sensitivity of these layers.
The faceted snowpack has little cohesion producing loose dry avalanches in steep terrain. This is concerning for ice-climbers and skiers in confined/exposed terrain.
Loose dry avalanches observed out of steep solar aspects at lower elevations, this loose snow has the potential to entrain the very faceted snowpack and gain mass quickly. Main terrain concern is when traveling in gully features while ice climbing.
Weak faceted layers from previous cold temps in the mid and lower snowpack remain a concern, particularly in shallow snowpack areas where facetting is more pronounced and triggering is more likely.

Forecasted snow amounts expected to be 10 to 30cms over the next 24 hours. Regardless of volume, this snow will fall on to a variety of surface forms (rocks, small surface hoar; facets, or hard windslabs).
15 cm of new snow in the last 24 hrs falls with moderate S winds is building a new slab.  Steady snowfall over the next few days will add load to this developing slab which sits on a weak layer of facets and surface hoar. 
35cm of new snow was accompanied by moderate S winds. This has created a new storm slab that is poorly bonded to a weak layer of facets and surface hoar.

While this layer still exists in the alpine and should be considered in shallow areas it is mainly TL and below where this sugary snow in the lower snowpack continues to produce moderate shears. Take extra care BTL where this layer is shallow
This layer is mainly a concern below treeline where the facetted snow in the lower snowpack continues to produce moderate shears.
Last weeks storm snow has settled into a 20-40 cm slab. This slab is starting to settle out, but snowpit tests show this layer to be reactive in some locations, particularly around treeline where surface hoar has been found.
Wind loading and shedding from steep faces, especially concerning for ice climbers.
Incoming new snow will not likely bond well to previous surfaces.&nbsp; Watch for fast running sluffs in steep terrain if snowfall amounts exceed 10cm.

Deeply buried Persistent weak layers from a cold winter have produced few results in recent testing, but are now being heavily loaded. In sheltered/windward terrain, this is the first large load on these layers. Avoid previously shallow areas.
Loose Dry avalanches will fail naturally in steep sheltered area. These will grow in size by Monday. Avoid extended time in features like gullies Below Treeline, where you will be exposed to overhead hazard, and avoid skiing above your partner.
Storm slabs are forming over a weak old snow surface that developed during the recent cold clear weather. Freshly formed slabs will be more sensitive to human triggering in wind exposed terrain.
Currently small in size, watch locally for their formation and the bed surface below. This can be facets, wind layers, surface hoar, or sun crust. As there is an easterly component, if there are increased winds watch for reverse loading.

10cm of storm snow over facets can be easily triggered and grow quickly by entraining surrounding snow especially in gulley features.
This is a weak and difficult to predict problem. We expect it to become more reactive now with more load, and once triggered may cause large avalanches running into the lower elevations. Avoid all big avalanche terrain.
The generally weak, facetted mid pack is producing moderate to hard shears. In the upper snowpack around treeline a buried layer of surface hoar produces variable shears. Current slab development will make triggering these layers more likely.
30cm of storm snow overlies a variety of surfaces to which it may bond poorly. Skiers have triggered small, unsupported slopes. As the snow settles and forms a slab expect it to become more reactive and capable of propagating into larger avalanches.

With freezing levels in excess of 2200m Saturday, the snowpack at lower elevations lost strength. As this snow refreezes, moist snow remains under surface crusts which large avalanches from upper elevations can entrain to reach surprising distances.
Several buried weak layers in the middle of the snowpack have become reactive again as they have been overloaded by recent snow and rain. Large avalanches are reaching historical run outs and crossing cross country ski trails.

As surface slabs fail, avalanches can easily step down to weak layers from late February, or deeper in shallow areas.
The entire snowpack is built upon a structurally weak base of facets. Large avalanches are reaching historical run outs and crossing valley bottom trails. Avoid exposure to overhead hazard and stick to moderate angled supported terrain.
Warming temperatures may create conditions for loose wet avalanches at lower elevations and on steep solar aspects over the next couple of days.
Several buried weak layers in the middle and lower parts of the snowpack have become reactive again as they have been overloaded by recent snow and rain. Large avalanches are reaching historical run outs and crossing valley bottom trails.
With warming temperatures we may start to see loose wet avalanches at lower elevations and on steep solar aspects over the next couple of days. Watch for clues like snowballing that indicate that the snow surface is warming.
The widespread observations of large and deep avalanches indicates strongly that many of the weekends avalanches went on this layer particularly where the snowpack is shallow and in rocky start zones.
It is an impressive and humbling time to be traveling in the back-country. Very large avalanches have been occurring, even logging mature timber. The scary thing is, these large avalanches continue to occur sporadically and are very hard to predict.

The widespread observations and explosive work creating large and deep avalanches indicates that many went on this deep layer particularly where the snowpack is shallow and in rocky start zones. Involvement in one would be fatal consequences.
Large avalanches continue to run to the valley bottoms and cross popular trails. We show this problem as being below treeline not because you can trigger an avalanche, but because you can be hit by one from above.&nbsp; Watch out for overhead hazard!

The month of March has been characterized by heavy loading of new snow and rain. These events have created an instable snowpack that is verging on a tipping point. Deep weak layers have been failing sporadically leading to large avalanches.
The lower snowpack is riddled with weaknesses particularly where the&nbsp; snow&nbsp; is shallow over rocky terrain.&nbsp; Today a&nbsp; large cornice failure triggered a size 3 slab on a NE treeline feature. Debris is running far into the valley bottom.
The month of March has been characterized by heavy loading of new snow and rain.  After an intense avalanche cycle, the snow pack is still stabilizing. Deep weak layers have been failing sporadically leading to large avalanches.
Natural activity is starting to taper, but the snowpack is still very weak. Most days this week, we have seen large avalanches running to valley bottom on this layer. Don't expose yourself to any avalanche terrain that hasn't recently avalanched.
Several buried weak layers in the middle and lower parts of the snowpack have been reactive in the last week as they were overloaded by snow and rain. Many large avalanches have run to historical run outs and crossed valley bottom trails.
The lower snowpack is weak with a crust from November surrounded by loose facets and depth hoar. This weakness is most developed in shallow snow with rocky terrain. A cornice failure triggered a size 3 on a NE treeline feature near Parkers ridge.

Spring is here! With daytime or solar warming the upper snowpack is becoming moist in the afternoon.  This moist slab is touchy below 1900m where a crust down 30 is providing a good bed surface for wet avalanches.
Increased daytime temperatures will result in a deteriorating snowpack structure below tree line. Keep a close eye on temperatures changes throughout the day, and the strength of solar inputs on steep solar aspects.

No crust recovery overnight and new snow will insulate the upper snowpack at lower elevations. If the sun comes out today, this problem will reach high into tree line and could trigger wet slabs or glide avalanches.
The snowpack throughout the region has a weak base and remains suspect. Approach all avalanche terrain with suspicion and exercise conservative route choices.  This problem will persist for the foreseeable future.
We wont likely see a great freeze Friday morning, and looks like we may see a decent amount of sun, especially in the East part of the region (Banff).  Watch locally for the amount of warming as we start the transition into spring conditions. 
No expectations for activity first thing in the morning but, as the day progresses expect to see snowballing, and loose slides on solar aspects at TL and below.
A decent freeze is possible in the Little Yoho region, but the forecast for clearing skies will heat up solar aspects as we transition slowly into spring.&nbsp;

Persistent weak layers deep in the snowpack continue to cause uncertainty, despite the surface layers being remarkably strong. Continue to avoid exposure to large slopes. Patience is a virtue as we wait for a melt/freeze cycle to change anything.
Wet snow flows like water in gullies during warm spring days, and the next few days we expect wet snow avalanches to be common in gully areas at and below treeline. Ice climbers - avoid steep low elevation gullies.
The snowpack is generally unstable, despite the strong feel of the surface layers. This next warm-up will again test the snowpack and we expect increased avalanche activity over the next several days. Patience is a virtue with this kind of problem.
