20-40 cm of new snow will form fresh storm slabs that will be thicker, stiffer, and more reactive in wind affected terrain.
Another storm pulse will develop thicker storms slabs that will be extra reactive in the lee of exposed terrain.
Storm slabs are expected to continue to develop due to forecast new snow and wind. Watch for the transition to moist or wet snow as you descend in elevation.

Recent stormy weather has been building touchy storm slabs. The problem is widespread but you can expect slabs to be especially reactive in wind affected areas with more variable snow distribution
Recent stormy weather formed storm slabs that may remain reactive on Saturday. These storm slabs are widespread but you can expect them to be especially reactive at higher elevations and in wind affected areas with more variable snow distribution.
Even as storm slabs gradually heal to the surface, south to southeast winds and light new snow inputs are incrementally loading the snowpack. Watch for this problem to become gradually limited to lee features in wind affected terrain.
New snow and wind inputs continue to promote storm slab formation. Expect slab formation to be more pronounced at higher elevations that see more wind effect.
Storm slabs and loose dry avalanches are possible in specific terrain.

Recent snowfall amounts are highly variable and somewhat uncertain throughout the region due to limited observations. Where higher accumulations exist, large storm slab avalanches are likely, especially in wind-affected areas.
The low density storm snow is being pushed and forming soft storm slabs. These are mostly limited to ridgeline, however they have been found in isolated open slopes at the upper limit of TL.
It may be possible to trigger deep storm slabs in any terrain over 35 degrees, and particularly exposed lee terrain and cross-loaded gully features where wind slabs have formed.
Weaknesses may exist within the storm snow and may be triggered by additional loading. Expect deep and dense wind slabs in exposed north through southeast facing terrain.

Large amounts of precipitation with freezing levels up to 1500 M in the western portion of the region. Wind and storm slabs have been quite active during the storm cycle producing large destructive avalanches. Use caution in wind loaded terrain !
Recent storm snow and high winds will have created wind and storm slabs that now sit above a weak layer formed in early December. It will take some time for these quite different layers to bond. Until then, the hazard will remain.
Any more new snow coupled with winds will only serve to make surface slabs more &quot;touchy&quot;.
Continued small amounts of precipitation have been accompanied by high winds, making for tricky situations in areas where the wind may have deposited dense wind packed snow.
Fresh snow transported by high winds is continually adding load to the upper snow pack.  It may be possible for light triggers such as a skier or a snowmobile to initiate an avalanche. Pay particular attention in areas recently wind loaded.
Stiff wind slabs, softer storm slabs and loose dry avalanches remain a concern as the region receives continued snowfall and NW winds. This problem will be most sensitive to human triggering in areas that have a crust down aprox. 50 cm.

Whumpfing has been observed over the last few days indicating that the storm slab is reactive to human triggering. This interface is highly variable across the forecast region, so diligent route-finding and conservative terrain selection is advised.
Strong winds, heavy snowfall, and high freezing levels over the weekend created widespread storm slabs at higher elevations. These slabs are expected to be gaining strength but may remain reactive to human-triggering for several days.

New snow has added to the recent storm slabs. Storm slabs may be easy to trigger where they are sitting on a crust. Storm slabs in motion may step down and release deeper persistent weak layers resulting in very large avalanches.
Lingering storm slabs may remain reactive to human-triggering, especially in wind loaded areas. Sun and afternoon warming may increase the reactivity of these slabs.

The incoming storm will dump up to 40cm at high elevations, approx 25cm at tree-line. This will provide the load necessary to make traveling in avalanche terrain something to avoid until the storm slabs have a chance to settle.
30-50 cm at treeline in past 24 hours and up to 80 cm in past 72 hours. Moderate SW winds producing storm slabs that are sitting on a weak facet layer. Widespread natural cycle in storm snow observed on Wednesday.
Up to 80 cm at treeline of recent storm snow and moderate SW winds have created storm slabs on a weak facet layer. The natural cycle is over but we still expect these slabs to be reactive to skier triggering.
Up to 50 cm of settled storm snow and moderate SW winds have created storm slabs on a weak facet layer. Whumphing and cracking was observed in the field, so skier triggering is still possible. Tree-line elevations seemed to be the most touchy.
Today, a field team observed whumphing and cracking at tree-line elevations where wind had created soft slabs. These slabs felt touchy on these specific, wind-affected areas. Human-triggering is still possible, given the right load on the sweet spot.
Another 20 cm overnight with strong winds will add to the avalanche danger. Avoid travel in avalanche terrain until the snow stabilizes with the cold front passage.
60 cm of storm snow over the last 48 hrs has created an unstable snowpack. North winds with the passage of the cold front have also loaded the normally windward aspects. Human triggering on steep slopes is likely. Avoid terrain over 30 degrees.

The storm slab is becoming more cohesive as a layer and bonding to older surfaces. While this is good in areas of a deeper snowpack (west of the Divide), this will continue to create touchy slabs east of the Divide and in thin, weak areas.
The storm slab seems to be bonding to older surfaces. West of the Divide, the storm slab is stubborn and harder to move, however slabs are still touchy east of the Divide where they overlie a weak, shallow, faceted snowpack.

Storms slabs vary between 30 and 40cm thick. In areas East of the divide the bond at the storm snow interface is weaker than areas farther West.
Storms slabs  (30-40cm thick) from last weeks storm persist in the alpine. Although the natural cycle has subsided these slabs still may be triggered by skiers in specific areas above treeline.

Recent storm snow has created a touchy slab condition in all open areas. Easy triggering of slabs is expected.
Storm snow accumulations since last Tuesday have been 60-80 cm or more. Both northerly and westerly winds with the storms have created storm slabs on most aspects. Touchy conditions and potential for large avalanches persist.
Expect new soft slabs to develop tonight and expect some reverse loading onto South aspects towards the end of the storm.&nbsp; Existing storm and wind slabs are 30-80 cm thick  Tonight's storm will add stress to the underlying weaknesses.
Slabs up to 60cm thick are slowly bonding to the old surfaces. These will be more sensitive to triggering from thinner areas East of the divide, but are present everywhere. Solar aspects over all regions will have these slabs sitting over sun crust.
This layer will likely be most reactive to human triggering where it sits on a buried crust (solar aspects) or in areas that have received wind effect. We may see some natural activity on this layer when the sun comes out and destabilizes it.

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.
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.
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.
Unlike the deep persistent slab problem, the storm slabs will eventually start to bond to underlying surfaces over the coming days.
These are confined to the immediate lees of ridgetops and will be fairly thin. 
Places which have a well defined sun crust will be the most susceptible to triggering a storm slab.&nbsp; At the moment these are of lower consequence and thin (15-30cm) and isolated to specific terrain features.
The recent storm snow and wind slabs will slowly begin to bond to the lower layers in the snowpack but this will take some time. Choose conservative terrain with no overhead hazard until this has a chance to bond.
The storm slab will settle over the next few days, but is currently very touchy. Most avalanches are initiating on this layer and quickly stepping down to the deeper weak layers.
Storm slab is still touchy and has potential to step down to deeper persistent layers.
The recent storm slabs are between 40 and 80cm thick. In general they seem to be bonding well but use caution in steep or wind loaded features.
The storms slabs will continue to settle. However, as they settle, they will become more cohesive and the likelihood of triggering will be the same for a few days yet.
Storm slabs formed in the last few days will be less sensitive to triggering as time goes on.  Forecast snow may build on these on Thursday.
Over 60 cm of snow has fallen over the past week, and that snow has now settled into a cohesive slab. Caution is advised in all avalanche terrain at treeline and above, in particular one should avoid exposure to avalanches during the heat of the day.
Storm slabs will continue to settle. These slabs will be touchy on Southern aspects in the afternoon.

15 to 30cm's of recent storm snow is bonding poorly to previous surfaces and remains reactive to skier triggering.
10-15 cm of snow expected on Monday night will combine with the existing surface snow to make a storm slab 30-50 cm deep in alpine areas. Human triggering is possible in gullies and convex slopes at higher elevations.
Total of 30 cm of snow since Jan 2 is mostly unconsolidated, but expect slab formation at higher elevations. Shears in this storm snow were occurring within the upper 25 cm. Any wind or warming will increase this problem dramatically.
Storm slabs will be rampantly forming and failing, especially at higher elevations. The bond to the Jan 30 interface and within the storm snow itself will be critical to monitor.
Storm slabs are the primary issue in the upper snowpack and failures will be occurring both within the colder low density and on the January 30th crust interface. This problem will be most prominent in the alpine and treeline bands on all aspects.

These are small in size and will be short in duration as a problem, but storm slabs were being triggered in numerous alpine locations Thursday.  On solar aspects these may be sitting on a sun crust. 
10-30 cms of new snow from Sunday night has formed soft slabs that are reactive in steep alpine lee areas. Touchiness will depend locally on snow amounts and wind speeds.
If the forecasted new snow amounts of 15-20 cm with strong SW winds show up, we will likely see storm slabs failing over the next 24 hrs with potential to step down to deeper layers. Stick to non-avalanche terrain until things have a chance to settle

Look for storm slab formation with warmer temps and forecasted snow amounts. Winds will be variable in direction through the storm period which may result in widespread slab distribution. These new slabs may also be sitting on previous wind slabs.
There are storm slabs up to 1m thick on many aspects and elevations from the big storm on Thursday. These will be highly sensitive to triggering and once initiated, can step down to the deeper persistent layers causing very large avalanches.

This problem is isolated to Kootenay and the region surrounding Sunshine where snowfall amounts were up to 35cm. Expect this problem to transition to a wind slab problem as the low density snow is redistributed by increasing wind.
Hot weather means cornice season, and this is the time when large mature cornices begin to fall off and the mountain sheds its snowpack. On ridges stay well away from cornices (they can reach back and get you), and avoid traveling under them.
20-30 cm of new snow is forming a soft slab and has been reactive to skier triggering. Places where this slab sits over a melt freeze crust may be the most likely to fail, but all steep terrain will be suspect for the next day or two.

Another 10cm in the last 24 hours continues to incrementally load the snowpack. Moderate winds have created soft slabs in exposed areas.
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.
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.
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.
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.
Storm snow instabilities still exist in the recent storm snow. Although it appears to be bonding well, another day or two of settlement and observations is needed before it is no longer considered to be a problem.
Snowpack tests yesterday showed instabilities in the upper 60cm in the moderate range.
The 40-50cm of snow from last week's storm continues to settle. Resistant planar results were seen in snow tests yesterday on this layer.
The storm slab is bonding well, as indicated in snowpack tests throughout the park. Use caution when entering wind-affected areas in the alpine and at tree-line.
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.
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.
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.
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.
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.
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
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.
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.
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.
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 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.
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.
20cm of additional load overnight totalling 1.2m over a weak layer which has been very reactive this past week. Riders have reported cracking, whoomphing and avalanches on this layer. This is in addition to any shallower storm snow instabilities.
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.
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 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.
Soft slabs can be expected at higher elevations which is sitting over a weak layers of sun crust and facets. As winds and snow amounts increase this slab will tighten up and become more reactive.
Soft slabs exist at higher elevations. They sit atop a variety of surfaces (suncrust, facets, wind slab), and have been touchy to human-triggering. As more snow falls and the temp's warm up, expect them to become cohesive and more reactive.
Field teams found touchy soft slabs in open alpine and tree-line lee features yesterday. These slabs appeared to be failing within the new snow, but some were popping very easily off the suncrust on solar aspects.
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.
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. 
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.
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.
30cm of heavy snow with wind fell yesterday over much cooler and lighter snow. This combination is what caused a large avalanche cycle. Storm snow instabilities will still exist in the upper 1m and will need some time to bond to be trusted.
Storm snow instabilities are present from snowpack tests yesterday. There is wind affect above treeline and lingering windslabs may exist in exposed areas.
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.
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.
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.
Lingering storm slabs instabilities may exist from the last storm two days ago and the associated wind. 2 crusts have been recently buried by this. Caution in more exposed areas where the wind had a chance to stiffen the snow.
The recent storm snow is settling into a cohesive slab, particulary in wind affected areas. Various weak layers within, and just below, the slab exist and may be triggered by skiers or snowboarders. It may become more reactive during sunny periods.
Snow amounts have slowly been accumulating over the last few days and storm snow instabilities may catch you by surprise. Caution on unsupported slopes or wind affected areas. This new snow is likely to produce some fast sluffing on steep slopes.
Trickling snow over the last 4 days amounted to 60cm at tree line. Instabilities in the upper snowpack from the recent snow load may exist particularly in exposed areas that saw some wind.
Storm slab instabilities newly formed soft slab in the lee of ridge crests may exist and pop with human triggering.
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.
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.
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.
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.
Soft slabs were observed in the Alpine by a field team yesterday in the Asulkan drainage, and rising winds this morning will likely create more. Avalanche activity this morning is attributed to this problem.
20cm of new snow with some added wind created some reactive conditions at the higher elevations these past two days. Watch for cracking and more 'slabby' feeling snow as you venture on the upper mountain specially in the lee of ridge features.
The snow load has steadily increased with winds up high. A surface hoar/crust layer is buried 30-40cm depending on aspect. As this snow becomes moist it will become more susceptible to human triggering.
We've had enough snow in the past few days to warrant some caution up high. Winds have been steady and combined with rising temperatures things will slab up a some more.
The 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.
High to extreme winds in the last 24 hours have formed wind slabs in exposed Alpine and Treeline areas where the snow was still soft and dry. Pockets of good dry snow may be found in protected North aspect areas above 2400m.
There may be lingering surface slabs at alpine and tree-line elevations, due to the strong winds accompanying the last snowfall.
The 10-15cm of snow from a few days ago was redistributed by strong winds, creating windslabs in exposed alpine and tree-line locations.
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.
Lingering shallower slabs at higher elevations may still be out there.
Recent storm snow may be sitting on good sliding surfaces such as surface hoar and crust. The winds picked up overnight so watch out for areas that may be wind loaded.
Recent storm snow may be sitting on good sliding surfaces such as surface hoar and crust.&nbsp; Watch for small pockets of slab reactive on steep solar aspects. Expect increasing hazard as the temperature rises.
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.
A heavy storm slab is building rapidly with moderate precipitation, warm temps and strong winds. It will bond poorly to the snow below and natural avalanches are occurring. Storm slabs may step down deeper resulting in very large avalanches.
A heavy storm slab that formed over the past 2 days will bond poorly to the snow below. Large natural avalanches have been occurring, running into valley bottoms. Storm slabs may step down deeper resulting in very large avalanches.
A heavy storm slab that formed over the past 3 days will bond poorly to the snow below. Large natural avalanches have been occurring, running into valley bottoms. Storm slabs may step down to deeper instabilities.
Storm snow layers up in the alpine are still suspect. We had 25cm of heavy snow over Dec 5 weak layer with strong winds. Some sunshine and the weight of a rider could be enough to trigger an avalanche.
Storm snow layers in the alpine are still suspect. The last storm cycle deposited ~25cm of heavy snow on an existing week layer in the upper snowpack. Some sunshine and the weight of a rider could be enough to trigger an avalanche.
Moderate to hard sudden planar test results down 25cm and 50cm were observed yesterday from the field team on Bruins Ridge. Because of this we will keep this as a concern for a little longer.
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.
A storm slab is developing, 25 to 30cm thick, at higher elevations and wind-exposed areas. These slabs will bond poorly to the surface hoar layer which it sits on. Avalanches on this layer may run farther than expected and easily entrain snow.
A 50cm slab sits over a very obvious surface hoar layer that reacted to human triggering yesterday. Sensitivity varies depending on drainage and elevation but the layer was observed to be almost everywhere and is a very real threat to riders.
A 50cm slab sits over a very obvious surface hoar layer that reacted to human triggering yesterday. Sensitivity varies depending on drainage and elevation but the layer was observed to be almost everywhere and is a very real threat to riders.
A 50cm slab sits over the December 17th surface hoar layer that reacted to human triggering yesterday. Sensitivity varies depending on drainage and elevation but the layer was observed to be almost everywhere.&nbsp; This layer is a real threat to riders.
A very touchy surface hoar layer is buried by a 50 to 70cm thick storm slab. This layer is widespread, and is likely to be triggered anywhere is has not yet failed. It is easily triggered by light loads (ie you), from distances of up to 100m away.

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. 
10-15cm of new snow with moderate winds last night. This has likely formed a thin storm slab in exposed ares, concealing existing wind slabs.  Riders may be surprised by this layer, as these avalanches have the potential to trigger deeper layers.
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.
Although powdery in most places, 25-35cm of new snow is gaining cohesion. Pockets of soft slabs will form near ridge crest where sufficient wind has gotten to it.
50cm of recent storm snow with more in the forecast. Settlement and winds have formed soft slabs particularly at ridge crests. Winds are on the rise and expect conditions to become more sensitive as winds continue.
70cm of storm snow since the New Year, moderate south winds and warming temperatures all translates into a settling surface slab. This will be most likely in highly wind exposed areas such as ridgelines and crossloaded features.
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.
The bond of the recent storm snow continues to improve however given the right location could still be reactive to human triggering. Steeper windloaded features at and above treeline should be treated with respect.
This layer is still producing results in snow profile stability tests but sings show that it is continuing to bond with the old snow interface. Steeper windloaded features at treeline and above should be treated with respect.
This layer has settled into a 40-50cm slab. The bond to old snow continues to improve, but human triggering is still possible in the right location. Use caution on steeper wind loaded features at treeline and above. Note slab changes as you travel.
There's 20-30cm of new snow overtop our latest surface hoar layer. This layer was observed to be widespread. As winds pick up and and the temperatures rise expect soft slabs to form and to be reactive to rider triggering.
~50cm of new snow overtop the widespread Jan 15 surface hoar layer. This layer was very reactive to human triggering yesterday. Expect this sensitivity to continue with the storm slab that formed overnight with the sustained strong southerly winds.
45cm+ of storm snow sits on the weak reactive January 15 surface hoar layer. Numerous natural avalanches to size 3 and skier triggered slides to size 2 have occurred over the last couple days on this layer.
40cm of new snow and strong southerly winds in have created a reactive storm slab. Expect storm slabs to be significantly thicker on lee features where snow has been transported by wind. This layer is easily triggered and will need time to stabilize.
We have 40cm of recent storm snow with very mild temperatures. Winds are strong in the alpine and its raining below 2000m.
40cm of storm snow was followed by 15mm of rain.&nbsp; This moist slab is likely to be touchy until temperatures drop below freezing.
~20cm of recent snow over a firm surface may be reactive to riders where wind has firmed it up enough to create a soft slab. Areas to watch for this are near ridge crests or cross loaded terrain features.
Soft slabs will be more prevalent today due to steadier overnight winds.  ~35cm sits on a firm, smooth layer providing a good surface for avalanches to slide on. Exercise extra caution near ridge crests or cross loaded terrain features.
Storm snow will be redistributed by mod southerly winds on to alpine lee slopes and crossloaded features. This storm snow sits on a firm smooth surface especially below 2200m. Take time to assess the snowpack while approaching wind affected features.
At treeline and above a soft slab is forming which sits on a firm bed surface. This storm slab is triggerable, and may propagate widely. In areas sheltered from the wind the loose storm snow may sluff on steep slopes, gaining mass.
A soft slab is forming which sits on a firm bed surface. This storm slab is triggerable and may propagate widely due to buried surface hoar on a crust. Continued loading through the storm will increase reactivity and the size of resulting avalanches.&nbsp;
25-30cm of heavy snow over lighter snow will make conditions dangerous until the rain and snow stop and temperatures cool down.
100mm of precipitation that fell as rain and snow is now sitting over the January 30 weak layer. This will make conditions dangerous until the rain and snow stop and temperatures cool down.
There is now about 1m of heavy storm snow above 1900m where temps have stayed below freezing. This storm slab is the triggering layer for recently observed large avalanches with far-reaching moist deposits.
With around 1m of settled storm snow over the last week, much of that rain below 1600m, time will be needed for instabilities within it to heal.
A warm, wet and windy storm over the weekend created a storm slab that is up to 1m deep. On lee slopes, wind loading may have made this slab much deeper and more reactive. 
A warm, wet and windy storm over the weekend created a storm slab that is up to 1m deep. On lee slopes, wind loading may have made this slab much deeper and more reactive. Tests indicate that the slab is stabilizing, but triggering is still possible.
15cm of overnight snow with moderate southerly winds have likely formed some soft slabs on and near ridge crests in the alpine.
Recent storm snow has likely formed some soft slabs on and near ridge crests in the alpine.

New snow continues to load the storm layer which is up to 40cm deep.&nbsp; In exposed lee areas, buried wind slabs within the storm snow will be difficult to identify visually.&nbsp; New&nbsp; snow, wind and warm temperatures will increase the hazard.
New snow continues to load the storm layer which is 40-60cm deep. In exposed lee areas, buried wind slabs within the storm snow will be difficult to identify visually. New snow, wind and warm temperatures will increase the hazard.
40-50cm of heavy storm snow will need some time to settle out and to bond to the crusts over which it lies. The associated winds were steady yesterday through the overnight period, creating soft slabs in exposed areas.
40-55cm of heavy storm snow over three days will need some time to settle out and to bond to the crusts over which it lies. The associated winds with the storm were steady creating soft slabs in exposed areas.

Storm slabs should be expected at tree line elevations and above in the immediate lee of ridge lines and crossloaded features. These slabs are lying over a number of crust and weak layer sandwiches that were previously reactive to skier triggering.
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.
Up to 60cm of new snow exists at higher elevations. Tests show poorly bonded storm snow where buried crusts are present. Hazard will increase when the new storm snow gets a rapid warm up this morning, especially if forecasted clouds don't arrive.
30-40cm of rapidly settling storm snow sits over a weak wet layer below 2300m. Stability tests indicate that this layer is triggerable by light loads. At higher elevations moderate winds have created pockets of wind slab and fragile cornices.
Snow accumulations varied greatly during the past two storms, more was received on the west end of the Park. Reactive slabs may linger in the alpine. Be aware as the snow transitions from crust to soft snow under your boards.
20cm of moist snow fell at treeline with consistent SW winds. The storm slab sits atop a crust on solar aspects and surface hoar on sheltered N aspects. Strong winds will continue to develop the slab properties of this layer and increase hazard.
40cm of recent storm snow sits over surface hoar on northerly aspects. Associated winds with the storms have been enough to create slabs in exposed areas. Its time to select more conservative terrain.

40cm of recent snow has settled into a slab sitting on surface hoar on N'ly aspects and a sun crust on S aspects. Strong winds at ridgetop have created deeper pockets and loaded lee slopes. Today's strong sun will likely make it more reactive.
If we get significant amounts of snow today, along with winds, the new slabs will be particularly touchy, given that they will be sitting on a house of cards (surface hoar and crusts).
25cm of heavy new storm snow has combined with strong SW winds to form a slab over a touchy, widespread surface hoar layer. This slab is easily triggered by riders and has the potential to propagate into larger than expected avalanches.

A 50-100cm thick slab overlies touchy surface hoar below treeline, and sun crust in the alpine. The surface hoar layer becomes more reactive at lower elevations, and where it exists the storm slab will be easy to trigger.
4-5 hours of low end of moderate southerly winds are expected to have formed soft slabs in the immediate lee of alpine and treeline ridges and cross winded features.
Periods of moderate winds from various directions have redistributed the snow around in the alpine producing surface roughness and soft slab
30cm of new snow may bond poorly to the old snow surface.&nbsp; Currently new snow is low density but with rising temps and forecasted wind gusts a slab could build.
25-35cm of new, low density snow is being moved around by the winds at ridge-top. This is forming a slab in lee features, which will likely have a poor bond to the underlying interface of surface hoar, sun crust, or facets.
Where wind-affected, touchy soft slabs are forming. At lower elevations, mild temp's are settling the new snow into soft slabs as well. At all elevations, these thin slabs may pick up speed quickly, pushing folks into terrain traps.
Storm slabs continue to develop as warm temps, wind and snow settlement turn the upper 40cm into a cohesive layer. Slabs are most developed in exposed alpine ares. This layer is easily triggered where it sits on preserved surface hoar crystals.

7hrs of moderate S winds have created storm slabs on alpine and treeline lee features. 
The settling storm snow is still reactive to skier/riders weight below treeline. In the Alpine windslab has formed from moderate s'rly winds.  With sunny periods forecast today expect the new snow to be more reactive with the sudden solar warming.
A new storm slab is building. 30cm of snow over 48hrs at treeline, with another ~15cm forecast, is settling into a slab with mild temps. This slab may be triggered by light loads (like you) and avalanches on this layer may step down to deeper layers.
Up to 50cm fell in 48hrs and settled into a storm slab rapidly. SW winds will have loaded lee slopes, forming even deeper slabs. This slab may be triggered by light loads (like you) and avalanches on this layer may step down to deeper layers.
This layer is once again primed for triggering thanks to ongoing strong winds. In exposed areas, this layer is a cohesive slab up to 60cm thick. It may be triggered by light loads and avalanches on this layer may step down to deeper layers.
Expect the storm slab to be touchy after another night of moderate S-SW winds.  On lee features and exposed areas the cohesive slab could be upwards of 60cm thick.  If triggered slides may step down to deeper weak layers.
The recent storm slab is gaining strength. The exception is in Alpine or at treeline where mod S-SW winds may have created a soft windslab. On lee and exposed features the cohesive slab could be 60cm thick. Slides may step down to deeper weak layers.
Since last weeks storm ~40cm of snow is forming into a storm slab. With more snow expected over the next few days this slab is thick enough to be a concern. In many areas it is still loose however in some areas tests indicate this slab is triggerable
~40cm of light snow remains loose in many areas and sluffs easily. As the storm progresses, it is expected settle into a slab with added snow, mild temps and SW winds. Watch for signs like &quot;upside-down&quot; feeling snow or cracking that indicate a slab.</span></p><p class="p_CC664AAA"><span class="s_AA239A9B">
50cm of storm snow is settling into a slab with mild temps, added precip and wind.  Field trip to Lookout notch yesterday confirmed this with upside down feeling snow along with cracking of the surface layer.
Upwards of 50cm of storm snow will be settling into a denser slab over low density snow that fell early last week.  The storm slab can be expected to shear in unsupported terrain.
Recent storm snow and wind deposits are settling rapidly over a layer of lower density decomposing precipitation particles. With the forecasted warm temps today this slab could become more reactive.
Recent storm snow and wind deposits are settling rapidly over a layer of lower density decomposing precipitation particles. With alpine temps above zero overnight this slab could become more reactive.
50cm of storm snow sits on isolated pockets of surface hoar and a curst on solar aspects.  Warm temps at low elevations and strong southerly winds have encouraged slab development. Stability tests show that this layer susceptible to skier triggering.
With up to 70cm of new snow at treeline and strong gusty winds over the last few days, expect avalanche conditions to be widespread. Human triggering is likely.
Skiers/boarders were triggering the storm slab yesterday. With an additional 15cm overnight and strong winds, this slab now packs a little more punch.
The storm slab will be a little more touchy once temp's warm up later in the day. It isn't the time to charge into aggressive terrain.

New, touchy storm slabs are forming with ongoing snowfall and wind-loading. On steep slopes, especially areas exposed to wind, expect slabs to be easily triggered. While they aren't very deep (yet) they move fast and can accumulate in terrain traps.
Touchy storm slabs have formed in some areas. On steep slopes, especially ridgecrests, roll-overs and areas exposed to wind, expect slabs to be easily triggered. These soft slabs move fast and can accumulate in terrain traps.
Sensitive storm slabs have recently formed in the forecast area. Ridge crests, convexities, steep features, wind and SOLAR exposed terrain are locations of particular concern. Expect these slabs to be easily triggered.

Moderate S'ly winds and 20cm of storm snow all landing on a facetted old snow surface should make for reactive storm slab at and above treeline.  Lingering windslab is also a concern and will be hidden under the new snow.
Moderate S'ly winds and 25cm of storm snow all landing on a facetted old snow surface. Where wind touched watch for a reactive storm slab at and above treeline. Recently buried windslab is also a concern more so on steeper solar locations.
Storm slabs will be most prevalent in the Alpine and areas at treeline where exposed to the wind. Previous wind slabs are now buried and slowly starting to heal. Cornice failures have tapered off, but it's still recommended to give them a wide berth.
Around 10 cm of new snow fell overnight with another 5-10 possible today. Expect this snow to be reactive at ridgetop or in steep unsupported terrain. This new slab buries an old windslab that was reactive on solar aspects.
Recent snowfall has created a touchy storm slab. Expect this snow to be reactive at ridgetop or in steep unsupported terrain. Sunny breaks are forecast today, even short bursts of the strong spring sun could make the new storm snow more reactive.

New snow and southerly winds have created reactive storm slabs. Slabs will be well-formed on lee features when wind has contributed to loading. These slabs are touchy and sensitive to human triggered loads as well as natural inputs like wind and sun.
Minuscule amounts of new snow fell with moderate winds overlying a solid snowpack. A storm slab may be most problematic where it's sitting on a crust and or on a surface hoar on a crust, where exposed to the wind.
15cm of recent snow and moderate winds have built a storm slab and may be most problematic where it's sitting on a crust, or on surface hoar over a crust where exposed to the wind.
Five cm of new snow fell overnight with Southerly winds gusting to 81 km/hr. Another 5cm is forecast today with sustained winds building windslab in lee features.  Pay close attention solar aspects where near surface crusts act as a good bed surface
20cm new snow with Southerly winds gusting to 80 km/hr has formed a storm slab. Another 10cm is forecast today with sustained winds building windslab in lee features. Pay attention on solar aspects where near surface crusts act as a good bed surface
60cm of storm snow buries a crust up to 2000m on all aspects and into the alpine on solar aspects. 30cm of new snow is settling quickly could be reactive to human presence. Moderate to strong winds have formed wind slabs on lee features.

Storm slabs may be susceptible to human triggering. Steep S aspects where the slab may sit on a sun crust and wind loaded features on N and E aspects are the main concern.
A layer of storm snow sits over windslab at and above treeline. Watch for wind loading in lee features. Expect these pockets around cornices, wind lips and roll overs. Solar input and a warming trend today may wake surface layers on S'ly aspects.
25cm of snow in the last 24hrs with strong to extreme winds has created widespread storm slabs on all aspects at Treeline and in the Alpine. Expect the strong winds to have scoured south aspects &amp; created firm windslabs on North facing slopes.
Over 30cm in last 48hrs initially accompanied by strong to extreme winds has created widespread storm slabs on all aspects at Treeline and in the Alpine. Expect the strong winds to have scoured S aspects &amp; created firm windslabs on N facing terrain.

Caution in steep terrain for failures within the recent storm snow.  The storm snow should start to settle out and bond over the next few days.
The new snow is bonding well but will settle slowly with the cooler temperatures.&nbsp; Watch for sluffing and soft slabs in steep terrain.
The recent snow has formed a soft slab in isolated areas that can be triggered by light loads. As winds pick up these slabs will grow and become more widespread. Monitor for slabs as you travel and use caution in unsupported terrain.
The snow from the last two storms is forming a slab. Things are a bit touchier over crusts right now. Both heating and wind will encourage slab development over the next few days. Use caution in steep or unsupported terrain.
With the forecast precipitation amounts, warm temperatures and strong SW winds you can expect natural and skier triggered storm slabs over the next few days on all aspects.  Lower elevations may also see moist or wet snow avalanches!
With mild spring temperatures and variable winds, new snow quickly settles into a slab. With sun and temperature crusts as a firm bed surface the bond of this new snow should be examined carefully before committing to steep or unsupported terrain 
Higher elevation, lee slopes and gully feature areas may have developed wind slabs during the storm that came in from the north. Evaluate the snowpack for stability prior to stepping into it. Limited field observations thus far this season.
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.
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.
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.
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.
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
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.

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.
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.
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 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.
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
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.
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.
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.
Skiers looking for dry snow on shaded aspects should frequently test the surface layers.&nbsp; A shear persists down about 30 cm&nbsp; with preserved stellar snow flakes and surface hoar. Caution in steep and unsupported terrain is advised.
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.
The weak snow above the crust is new primed with a big enough slab for there to be serious consequences of triggering an avalanche. Isolated areas that hold surface hoar should be treated with even more respect.
The 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.
Where there are no surface crusts these slabs may remain available for triggering particularly where they have been influenced by the wind.
The pineapple forecast for Thursday will change things in a hurry: with warm temps and strong winds, expect rapid slab formation TL and above. With a freezing level of 2000m expect loose wet, or thin wet slab activity BTL.
The low forecast for Thursday will change things in a hurry for the weekend: with warm temps and strong winds, expect rapid slab formation TL and above. With a freezing level of 2000m expect loose wet, or thin wet slab activity BTL.
These slabs could grow rapidly with mild temps, moderate winds and heavy snow forecast. If freezing levels rise wet slabs could be very touchy at lower elevations. Monitor slab depths and resistance by feeling for the crust. Watch forecasts closely.
At upper elevations the new snow combined with mild temperatures and strong SW winds has created 50cm soft slabs. Rain crusts overly these new slabs to 2200m. Be cautious with steep or unsupported terrain until these slabs can settle and cool.
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.
The slabs are continuing to build on N and E aspects with snow transport from strong SW winds. These will become more reactive with daytime heating. Large cornices could provide a trigger for avalanche activity and could be weakened by the heat.

Storm slabs will continue to grow through the weekend.
These are currently thin and isolated, but will increase if we see the new snow Saturday and Sunday nights, that some forecasts predict.  The wind will blow any new snow onto lee slopes near ridge crests -use increased caution in these areas.
Fresh storm slabs remained touchy through the weekend. These can be managed readily with ski cutting in appropriately non-consequential terrain, but may be large enough to be destructive in bigger terrain features.
<br />Expect new snowfall, warm temperatures and wind to build new storm slabs on Sunday / Sunday night. These may be large on isolated lee slopes.  They will become less sensitive to triggering later in the forecast period.
Isolated storm slabs exist,&nbsp; increasing in size with elevation. These may be stubborn or unreactive to human triggering, but consider the consequences of your terrain choices if peak bagging.
Strong wind and heavy precipitation will cause rapid storm slab development in lee areas on Thursday.
Snow showers through the weekend will continue to add to the load on the early March crust.  With this crust as a potential weak interface these storm slabs may be slow to strengthen.
New snowfall and wind loading has created thick storm slabs on many lee slopes. These have been bonding poorly to crusts below. They will slowly become less sensitive to triggering with the cold temperatures forecast.
Storm slabs are variable in distribution and thickness, but currently exist on many lee slopes. Use particular caution on steeper slopes, and consider the consequences of your terrain choices.
With snowfall and wind in the forecast storm slabs may develop in the coming days. These will not likely bond well initially to the widespread crust that is currently on the surface.
With winds tapering toward the end of Friday's storm windloaded pockets may be difficult to detect.
These will be largest, and most widespread, on S and W aspect lee slopes at Alpine and Treeline elevations. However, new snow may also overload small buried wind slabs that exist near ridges, lee to previous SW winds.
These will be widespread, but most prevalent on S and W aspect lee slopes at Alpine and Treeline elevations. Sensitivity will increase with slope angle, and especially if temperatures approach 0 degrees, and/or / during strong sun.
Sensitivity of these storms slabs will vary depending on the underlying bed surface.  Be especially cautious in areas where the new snow overlies a crust.
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.

This problem will grow throughout the forecast period, and may be widespread. Pay attention to obvious signs of instability, do snowpack tests on representative slopes, and only expose one at a time. Conservative decision-making is essential.
Likelihood of Storm Slabs in previous storm snow will decrease somewhat during the forecast period; however, they may be slow to bond with old surfaces, and can be surprising deep.
While deep Storm Slabs from last weeks heavy snowfall have gained some strength over the past few days, this weeks warm temperatures may increase the likelyhood of triggering them.
While deep Storm Slabs from last weeks heavy snowfall have gained strength, they sit over a facet-crust combo on solar slopes below 2100m, and over facets (slowly strengthening) in sheltered/treed areas. If triggered, these may be destructive.
Fresh Storm Slabs are forming, specifically lee to SW winds. These overlie a widespread, stubborn older slab (70cm thick). This sits on a facet-crust combo on solar aspects below 2100m, and on hollow facets (slowly healing) in sheltered/treed areas.

Fresh Storm Slabs will likely form this week with snow and moderate wind in the forecast.
Storm Slabs exist on Thursday, but will grow in size and sensitivity on Friday, and will remain primed for human triggering on Saturday. Pay special attention to slopes lee to SW winds - these winds will build touchy slabs on lee slopes.
Storm Slabs will be touchy. Pay special attention to Treeline and Alpine slopes lee to SW winds - slabs will continue to grow on these slopes. Avoid steep slopes where wind transported snow is being deposited.
Old storm slabs were settling before Tuesdays precipitation, but increased load from further loading means it is worthwhile digging to test this slab. New snowfall with SW wind &amp; warm temps will create fresh, reactive storm slabs on lee slopes.
New snowfall with SW wind &amp; warm temps will create fresh, reactive storm slabs on lee slopes. Expect these avalanches to be largest near the divide, including Cameron Lake area.&nbsp; Heavy snowfall is possible in Western areas on Saturday.
New snowfall with SW wind &amp; warm temps has created fresh, reactive storm slabs on lee slopes. Expect these avalanches to be largest near the divide, including Cameron Lake area.
These still exist in steep Alpine terrain, on lee aspects away from the wind, where warm heavy snow on Saturday fell on colder snow below. These are largest along the borders of Montana and BC (blame them!), as snowfall was heaviest in the West.
Incoming snow and wind will likely form slabs. These will become particularly touchy if snowfall turns to rain.
Watch for isolated pockets of slab in alpine lee and crossloaded areas.
New snow arrives in the alpine on Thursday. Rising winds Thursday into Friday will create storm slabs on lee slopes, which may be reactive where they overlie hard crusts.
Storm Slab pockets exist lee to West and SW winds, especially immediately behind ridge crests, outcrops, and islands of trees (&quot;immediate lees&quot;). It is possible a person or solar radiation could trigger these. This problem will lessen over time.
Exposed areas saw wind transport Thursday night, and may do on Friday night also - just enough to set up isolated storm slabs in unusual (South and West facing) lee features.  These could be reactive; particularly on Saturday, and during midday sun.
