Conditions are ideal for the formation of new storm slabs at higher elevations, with steady snowfall, warm temperatures, and increasing winds. Storm slabs may step down to a more deeply buried persistent weak layer to create even larger avalanches.
Snowfall and warmth are adding load and stressing a persistent weak layer now buried about 60 cm deep. Human triggers or storm slabs that trigger this layer may result in very large avalanches.
Warmth has been transforming low density snow into potentially touchy slabs over a 30 cm-deep weak layer. This weak layer is most prominent below 1600 m. Releases of newly formed wind slab could be a great trigger for this layer on Saturday.
Light snowfall and loose snow on the surface will be stripped from windward areas and packed into growing pockets of wind slab on lee slopes on Saturday. This problem will be increasing over the day. Loose wet avalanches are a concern below treeline.

everal different weak layers can be found in the snowpack, they are now deeply buried, and they have produced large avalanches as recently as Monday. It remains prudent to assume these layers are present, reactive to human triggers, and capable of forming very large, destructive avalanches.
The heavy load of recent snow is supported by a weak snowpack near the bottom of the snowpack. Recent avalanches failing on this layer produced very large destructive avalanches. Natural avalanche activity has declined, however additional load (such as a person, snowmobile, or cornice failure) could potentially trigger a large destructive avalanche. Triggering is most suspect in steep terrain with thin or variable snow cover.

This layer/interface is down about 110cm at treeline. This gives a somewhat false sense of security. The snow \"feels\" good, but a shallow area could very easily trigger a large avalanche. Be diligent and choose supported terrain with no convexities.
Settled snow from previous storms has formed a slab on weak surface hoar 100 to 160 cm below the surface. Natural avalanche activity has waned, but human triggering may still be possible, especially in more challenging/complex terrain that hasn't avalanched since the weak layer was buried. This isn't the kind of avalanche problem you can feel under your skis, track or feet, it's far too deep for that. The answer lies in terrain selection.
There are multiple problematic weak layers in our snowpack between 70 and 180 cm below the snow surface that continue to produce spectacularly large and destructive avalanches. The weakness and complexity of this snowpack is unique, it's not something we see every season. Although most of the very large recent avalanches are triggered in the alpine and triggering is less likely below treeline, the ability of large avalanches to run to valley bottom means that they pose a hazard even below treeline. Conservative terrain selection at all elevations is critical.
A buried crust can be found in the middle of the snowpack which we'll need to watch carefully as storms begin to roll in this weekend.  Avalanches failing on this interface could step down to the ground, especially in places of smooth ground cover like grassy slopes, rock slabs, glacial ice, etc.

Around 40 to 60 cm of snow accumulated in the region, forming a widespread natural avalanche cycle. Storm slabs may remain touchy to human traffic on Wednesday. It would be wise to stick to non-avalanche terrain at higher elevations until the snowpack stabilizes. Make assessments as you travel and do so conservatively until there is evidence that the recent snow is bonding.
A buried weak interface of crust and surface hoar can be found in the middle of the snowpack.  While difficult to trigger, avalanches failing on this interface could be suprisingly large.
80-100 cm of recent storm snow combined strong winds have promoted storm slab development. Watch for solar triggering of recent snow on steep solar aspects during periods of sun.

Thicker slabs are found in wind-loaded terrain features, particularly near ridges. Conservative terrain selection is required to avoid this avalanche problem.
Many storm slab avalanches have occurred in the region with the wallop of snow that has accumulated in the past few days. The slabs are likely deepest and touchiest in lee terrain features at treeline and alpine elevations and in large openings below treeline. These slabs may take more time to stabilize as the region continues to receive more snowfall in the coming days.

Large reactive storm slabs continue to grow with another storm pulse crossing the region on Tuesday night. Natural avalanches are likely in the alpine due to strong wind throughout the day, while human triggering is a concern in steep terrain at all elevations.
Another powerful storm pulse is taking aim at the region setting up to deliver upwards of 40 cm of new snow by the end of the day. High snowfall rates, strong winds, and rising temperatures mean that Increasingly thick and reactive storm slabs will form during the day
Variable forecast snowfall amounts will build new surface instabilities on Tuesday. In the west of the region, thick new storm slabs are forecast to form by the end of the day. Closer to Smithers, light new snow will combine with elevated southwest winds to form very touchy, but less widespread wind slabs.

Accumulations of new snow over the past week have formed reactive slabs in steep wind affected terrain.
New snow and strong to extreme winds are expected overnight through Thursday afternoon, which should reinvigorate the formation of fresh, sensitive storm slabs. New slabs will overlie heavily wind affected surfaces, which could allow for them to move fast and be very sensitive to triggers.

Lots of new snow has accumulated over the week and 20-30 cm more is on the way for Saturday. Reactivity of the new snow is to be expected, but there is concern for mid and pre-storm interfaces reaching a critical load with the new snow as well.

Wind fueled storm slabs can be found in the alpine and may be most sensitive on solar aspects where they rest on a sun crust.
Around 20 to 40 cm of snow is sitting on top of a widespread layer of surface hoar found at all elevations and on all aspects, and more snow will slowly accumulate in the coming days. On sun-exposed aspects, the surface hoar is sitting on a melt-freeze crust, which is a particularly nasty combination. To date, the layer has been most reactive between around 1700 and 2300 m and where the overlying snow has gained slab properties from snow load and wind affect. This elevation band of reactivity may increase in the coming days as new snow, strong wind, and warming air temperature may increase slab properties.
Warming temperatures and periods of sun are expected to promote cohesion in the recent snow over a lingering layer of buried surface hoar (February 22), making human-triggered avalanches likely. This problem will be more pronounced where the wind has drifted the recent snow. Although less likely, a more deeply buried surface hoar layer (February 13th) down 60-80 cm may also become more reactive as a persistent weak layer with warming temperatures.

20 to 35 cm of snow from the past weekend has formed storm slabs that have been producing avalanches up to size 2.
A 20 to 30 cm slab has been reactive to riders in the past few days. The slab has been touchiest in open trees around Kootenay Pass, where it rests on a layer of weak and feathery surface hoar. The spatial distribution of the surface hoar layer is unclear and may be spottier in the remainder of the region. Near ridge lines, the slab has been touchiest in lee terrain features due to recent wind transportation.
Wind slab formation may resume with increasing winds Wednesday with what little snow remains available for wind transport in the alpine. Fresh wind slabs will be especially sensitive to human triggering.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":107,"length":14,"key":0}],"data":{}},{"key":"com04","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"bv7ih","text":"Steep sheltered slopes at lower elevations remain capable of producing human triggered storm slabs particularly in parts of the region where more than 30 cm of recent snow sits over surface hoar.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}}],"entityMap":{"0":{"type":"LINK","mutability":"MUTABLE","data":

Storm slab avalanches are possible to trigger on wind loaded or steep convex slopes, and may release naturally on sun-exposed slopes in the heat of the day.
Snowfall Friday night may not bond well to underlying layers of weak surface hoar crystals, faceted grains, or a melt-freeze crust. The most snow is forecast in the northern half of the region, where upwards of 15 cm may accumulate. The southern half of the region may only see 5 cm. Nonetheless, the snow will fall with strong westerly wind, so slabs will be thicker and potentially touchier in lee terrain features.
Storm slabs are expected to build over the day as the storm passes. Snowfall rates could reach 3 to 5 cm per hour and winds are expected to be strong from the southwest. The snow will fall onto a weak layer of surface hoar and may not bond to it.
As of Monday morning we have received 10-20 cm of fresh snow and could expect a bit more throughout the day. New snow is sitting on a wide variety of old surfaces including facets and surface hoar which may allow for particularly touchy storm slabs on Monday.
Around 10 to 15 cm of snow is expected to accumulate Friday night, which will fall onto a weak layer of surface hoar crystals. The snow will likely form slab properties quickly, as it will fall with strong westerly wind. This is a recipe for storm slabs that could be likely to trigger and that could propagate far.

A thick rain crust can be found 30 to 60 cm below the surface. As temperatures warm and slopes are subject to the sun, the overlying slab could start to wake up. Large cornices are a potential trigger for these slabs.
A thick rain crust can be found 30 to 60 cm below the surface. As temperatures warm and slopes are subject to the sun, the overlying slab could start to wake up.  Strong sun and warming temperatures are also likely to warm cornices which could trigger avalanches when they fail.
Storm slabs are a serious problem at all elevations, and we need to be extra cautious at and below treeline where up to 60 cm of snow rests on well-preserved surface hoar. The alpine is a different story, at that elevation the storm snow has been heavily affected by wind and slabs are 30 to 90+ cm in depth. Storm slabs may rest on a melt-freeze crust on sun-exposed aspects too. The deepest deposits will likely be in lee terrain features near ridges, as the snow fell with strong south to west wind.

Snowfall continues to load a widespread layer of surface hoar found at all elevations. On solar aspects the surface hoar is sitting on a crust, which is a particularly nasty combination. There is currently 20 to 40 cm of snow that overlies it and another 5 to 15 cm of snow is forecast until Wednesday afternoon. This problem will become reactive once enough snowfall has accumulated and slab properties form. There is uncertainty on when exactly this will occur, so you should travel conservatively and assess this layer before committing to avalanche terrain. Also be aware that snowfall is occurring with strong southwest wind, which will load lee terrain features near ridges quickly.
Continued snowfall and wind adds to an already serious avalanche problem.  By Thursday morning up to 50 cm of new snow and 60 cm of older snow (for a total of over 100 cm) may be resting on well-preserved surface hoar at and below treeline. This kind of setup could open the door to a situation where it \"goes electric\" as deep avalanches run naturally in sheltered terrain at and below treeline.  Even deeper slabs are expected in the alpine as strong southwest wind continues to build thick wind fuelled storm slabs. Solar aspects (those that face south and west) have a buried crust that could serve as a bed surface for very large avalanches.
A widespread layer of surface hoar found at all elevations and on all aspects is starting to become reactive to human traffic. The layer is buried around 30 to 40 cm deep. On south aspects, the surface hoar may be found overlying a melt-freeze crust, which is a particularly nasty combination. To date, the layer has been most reactive between around 1700 and 2300 m and where the overlying snow has gained slab properties from snow load and wind affect. This elevation band of reactivity may increase in the coming days as new snow, strong wind, and warming air temperature may increase slab properties.
Storm slabs are expected to remain sensitive to human triggering, as warming temperatures and periods of sun promote rapid settlement of the slab over a weak interface. Storm slabs will be deepest and most reactive where wind has loaded lee terrain features in alpine and exposed treeline areas. Recent winds have varied in direction from south to northwest, wind loading a variety of aspects.
50 to 100 cm of snow from the past week combined with strong southwest wind has left thick reactive slabs. This snow may be resting on well-preserved surface hoar at and below treeline. South and west facing slopes may also have a buried crust that could serve as a bed surface for large avalanches. Overall there is serious potential to trigger large slab avalanches in the wake of the storm.
Recent storm snow adds another 10-25cm of snow load on top of a widespread layer of surface hoar found at all elevations and on all aspects.  This layer has already been reactive to human traffic and avalanches will likely increase in size as slab properties increase. The layer is buried around 40 to 65 cm deep. On south aspects, the surface hoar may be found overlying a melt-freeze crust, which is a particularly nasty combination.  However, recent skier triggered activity has been higher on northwest to easterly aspects.

New snow and wind will form dangerous storm and wind slab avalanches on Thursday. Natural wind slab avalanches will be likely in alpine terrain and dangerous storm slabs could form at all aspects and elevations in parts of the region that receive more than 20 cm of new snow. Natural avalanche activity should reduce on Friday and Saturday, but storm and wind slabs will remain reactive to human triggers.
A rather volatile layer of buried surface hoar is 60 to 130 cm below the surface. This layer continues to produce very large natural and human triggered avalanches.  Large cornices that loom over many slopes are on the brink of failure. Failing cornices are likley to produce large avalanches when they impact slopes.
60 to 130 cm of snow from the past week combined with strong southwest wind has left thick reactive slabs. This snow may be resting on well-preserved surface hoar at and below treeline. South and west facing slopes may also have a buried crust that could serve as a bed surface for large avalanches. Overall there is serious potential to trigger large slab avalanches in the wake of the storm.
30 to 50 cm of storm snow rests on a widespread layer of buried surface hoar. These slabs have been most sensitive to triggering at lower elevations (at and below treeline) which is a setup that can catch us off guard. Wind fueled storm slabs can be found in the alpine and may be most sensitive on solar aspects where they rest on a sun crust.
Snowfall continues to load a widespread layer of surface hoar, with about 30 to 50 cm overlying it now. This layer has been most problematic in the south of the region. So far, the layer has been most reactive at treeline and alpine elevations, where the recent snow has been redistributed by the wind and formed a slab above the surface hoar.

A widespread layer of surface hoar found at all elevations and on all aspects has been reactive to human traffic. The layer is buried around 35 to 50 cm deep. On south aspects, the surface hoar may be found overlying a melt-freeze crust, which is a particularly nasty combination.  However, recent reported reactivity has been on northwest to easterly aspects.  To date, the layer has been most reactive between around 1700 and 2300 m and where the overlying snow has gained slab properties from snow load and wind affect. This elevation band of reactivity may increase on Saturday and Sunday with forecast new snow, strong wind, and recent warming trend, which all may increase slab properties.
Additional new snow continues to load a widespread layer of surface hoar, with about 30 to 50 cm overlying it now. This layer has been most problematic in the south of the region. So far, the layer has been most reactive at treeline and alpine elevations, where the recent snow has been redistributed by the wind and formed a slab above the surface hoar.
35 to 50 cm of snow overlies a widespread layer of surface hoar found at all elevations and on all aspects.  Recent warm temperatures have settled this snow into a more cohesive slab in mid and low elevations, making it more likely to produce large avalanches.  To date, the layer has been most reactive between around 1700 and 2300 m and where the overlying snow has gained slab properties from snow load, settlement and wind affect. This elevation band of reactivity may increase in the coming days as new snow and strong wind continue to increase slab properties.
Variable snowfall amounts will accumulate across the region on Tuesday night, with amounts from 15 to 30 cm expected. Both storm and wind slabs will rapidly develop during periods of intense snowfall and strong west wind. Use added caution if you find more than 25 cm of snow accumulate from the storm. Sunny periods on Wednesday could rapidly destabilize the snow on sun-exposed slopes.
30 to 50 cm of settled snow rests on a widespread layer of buried surface hoar. While this weak layer is thought to be present at all elevations, these slabs have been most sensitive to triggering at treeline which is a setup that can catch us off guard. Watch for deeper slabs at ridgecrest too.
A weak layer of surface hoar sits 40-70 cm deep. Read more about surface hoar on our forecaster blog!

Widespread storm slabs will be a serious problem on Wednesday with 20 to 60 cm of snow falling in the last 24 hours with strong to extreme wind from the west. Natural activity is possible on freshly wind loaded slopes and human triggering remains a concern in steep terrain at all elevations. The fresh storm slabs combined with several persistent slabs makes the consequence of triggering any avalanche high.
Around 20 to 30 cm of snow is forecast to accumulate across the region on Thursday. Storm slabs will grow over the day and become touchy during periods of rapid loading from snowfall and/or strong wind. The snow will fall with strong southwest wind, so the deepest deposits will be in lee terrain features. Use added caution if you find more than 20 cm of snow accumulate from the storm.
Additional new snow continues to load a widespread layer of surface hoar, with about 30 to 70 cm overlying it now.  This layer appears to be reaching \"threshold\" where human triggering is likely.  Watch for signs of instability such as shooting cracks and whumphing.   So far, the layer has been most reactive at treeline and alpine elevations, where the recent snow has been redistributed by the wind and formed a slab above the surface hoar.
30 to 50 cm of total recent storm snow and strong west winds have formed wind slabs in many areas. Wind slabs will be most reactive in lee terrain features.
Large dangerous storm slabs will form on Thursday with another 20-40 cm of snow and strong to extreme wind in the forecast. Fresh storm slabs combined with several persistent slabs makes the consequence of triggering any avalanche high.
35 to 60 cm of snow overlies a widespread layer of surface hoar found at all elevations and on all aspects.

Large persistent slab avalanches are possible due to weak layers buried 30-50 cm below the surface. These layers of surface hoar, facets, and crusts have been reactive in recent snowpack tests and will become extra sensitive with the weight of the new snow. Conservative terrain choices are the best way to manage the uncertainties associated with this problem.
Storm slabs formed during the weekend's storm may remain touchy to human traffic. With the substantial amount of snow that fell, it may take a bit more time for the snow to stabilize. If triggered, storm slab avalanches may step down to a buried weak layer, forming destructive avalanches that could travel far.
Three different weak layers may be found in the snowpack. It is uncertain whether the rapid loading from the storm cleaned them out and hence whether they will remain a concern in the distant future. Until more evidence exists, it is prudent to assume the layers are present and capable of forming very large, destructive avalanches. Best to avoid alpine terrain until the uncertainty about these layers decreases.

Shallower storm slab releases carry the risk of triggering a deeper weak layer to create a larger, more destructive avalanche.
A pair of touchy weak layers are buried deep in the snowpack near and above tree line, and the consequences for triggering either one are severe. These layers have been responsible for many very large avalanches in the region over the past two weeks. Shallower but more reactive wind slabs may also step down to one of these deeper layers and create a very large, very destructive avalanche.

Forecast snowfall is expected to form touchy new slabs that will be primed for human triggering on Wednesday. The consequences of triggering a slab of new snow are greatly amplified by the fragile nature of the region's lower snowpack.
Several persistent weak layers are buried in the snowpack. It still may be possible for humans to trigger them, or for storm slab avalanches to step down to them to form very large avalanches.
There is still concern for heavy loads (storm slab avalanches running) to step down and trigger deeper weak layers buried in December.
60-90 cm of snow has accumulated in the past week over a layer of surface hoar from late December. This layer has demonstrated reactivity past its due date as a storm slab interface and has produced large avalanches across aspects and elevations with incremental loading from new snow and wind.

Below 1800 m, the snowpack is becoming saturated by heavy rain. Elevations that have not previously experienced above freezing conditions, or where snow accumulated before turning to rain will be especially susceptible to loose wet avalanche activity.
elow 1800 m, the upper snowpack is being soaked by rain. Elevations where snow accumulated before turning to rain will be especially susceptible to loose wet avalanche activity.
Significant loading from recent snow, rain and ongoing wind weigh heavily on deep weaknesses near the bottom of the snowpack at alpine and treeline elevations. Failure of these weak layers has produced very large, destructive avalanches. Potential exists for these avalanches to run to valley bottom; hence, this problem poses a hazard to all elevations. These layers do not pose an avalanche problem in the south half of the region.
The combination of rapid snowfall, strong winds, and fluctuating temperatures have added considerable strain to a deeper weak layer buried in the snowpack.

Sunday's storm snow and strong southwest wind is expected to form fresh sensitive slabs at all elevations. Storm snow will likely come to rest on yet another layer of surface hoar which is  expected to allow for touchy new storm slabs.
A weak layer of near surface facets and surface hoar from February 22 will likely get buried down 40-70 cm. On solar aspects, these weak grains may be accompanied by a crust. As new snow and wind add to the slab above, there is growing concern for the size and likelihood of avalanches on this persistent weak layer.

Around 30 to 50 cm of snow overlies a weak layer of surface hoar. The layer has been most problematic on northwest to northeast aspects, but avalanches have also occurred on southerly aspects. The likelihood of triggering this layer on Wednesday may increase on southerly aspects due to periods of sunny skies. Avalanches have occurred from 1600 m to 2300 m in the region. Assess the layer prior to committing to avalanche terrain or adopt a conservative mindset to avoid the problem.
Additional new snow continues to load a widespread layer of surface hoar, with about 25 to 50 cm overlying it across the region.   So far, the layer has been most reactive at treeline and alpine elevations in the Western (and deeper snowpack) regions of the forecast area and where the recent snow has been redistributed by the wind and formed a slab above the surface hoar.

New snow accumulations exposed to strong sunshine will be increasingly likely to shed from steep slopes on Thursday. This may occur naturally or with a human trigger.
Storm slabs may build over the day, as 10 to 20 cm of snow is forecast to Saturday afternoon. The snow may form slab properties quickly in lee terrain features, with light to moderate southwest wind forecast. If triggered, storm slabs could step down to the buried surface hoar layer, forming large avalanches.
30 to 60 cm of settled snow rests above a widespread layer of surface hoar that produced numerous avalanches last week. These slabs have been most sensitive to triggering at treeline.

40 to 90 cm of settled snow rests above several layers of buried surface hoar that have produced avalanches over the past week. These slabs have been most sensitive to triggering in sheltered areas at treeline. Warming is expected to increase the likelihood of triggering these layers.
Multiple surface hoar layers have been buried by successive storm events and have shown continued reactivity to human triggering. These layers can be found buried 35-50 cm, 70-120 cm, and 110-160 cm below the surface. These weak layers are most problematic at treeline elevations where the surface hoar is well preserved. Rapid warming is expected to increase the likelihood of triggering deeper layers.
A weak layer of surface hoar exists 40 to 80 cm below the surface and has produced a few large avalanches over the past few weeks. The problem seems most prevalent on northwest to northeast aspects between 1700 m and 2100 m. While the likelihood of triggering a persistent slab avalanche is dropping, there is still some uncertainty about where and for how long this problem will persist.
Loose wet avalanche activity is most likely during the heat of the day on sun-exposed slopes. Cornices will also weaken with the warming trend.

Modest air temperature and sunny skies combine to weaken the snow surface. As this occurs, loose wet avalanche activity may result. The highest likelihood of this occurring is during the heat of the day on sun-exposed slopes. Note that the same warming trend also weakens cornices, so best to stay well back from them on ridges and avoid travelling beneath them.

Loose wet slides will start in the PM with daytime warming.  Steep solar slopes especially in thinner areas will be places to avoid.  Any small slide may step down to the deeper basal layers.

New snow accumulations exposed to strong sunshine will be increasingly likely to shed from steep slopes on Thursday. This may occur naturally or with a human trigger.
Heavy rain is expected below 1300 m. Saturated snow on steep slopes will likely become unstable.
This is our main concern for treeline and alpine areas. Those deep layers are weak and prone to collapsing with any additional load.
Snow is forecast to accumulate throughout the day, and favored areas in the region may see 25+ cm. Moderate southwest winds are expected to increase slab formation in drifted areas.
Wet loose avalanche conditions should ease as temperatures drop on Monday, but surface snow will remain unstable at elevations that continue to see rain accumulating instead of new snow. Be conscious of this problem around steep slopes at lower elevations.
Wet loose avalanches will be in increasing problem on Friday at lower elevations that see rain instead of snow accumulating. This problem will affect increasingly high elevations over the day.
Below 1800 m, the snowpack is being soaked by rain. Elevations that have not previously experienced above freezing conditions, or where snow accumulated before turning to rain will be especially susceptible to loose wet avalanche activity.
Wet loose avalanches will continue to be a concern on Saturday at lower elevations that see rain instead of snow accumulating. This problem is expected to decrease in likelihood as the freezing levels drops throughout the day.

As recently as Tuesday, explosives testing continues to periodically trigger a weak layer of snow at the bottom of the snowpack, producing very large and destructive avalanches. Significant loading from recent snow, rain and ongoing wind weigh heavily on deep weaknesses near the bottom of the snowpack. If triggered, these layers would produce large avalanches with the potential to run to valley bottom.
Intense solar radiation is expected to initiate wet loose avalanches. This activity will likely be confined to steep slopes that face south through west. Minimize exposure to sun-exposed slopes during periods of strong solar radiation.

A weak layer of surface hoar is buried 50-100 cm deep and even though avalanche reports decreased over the past week it is still possible to human-trigger. Over the past two weeks, large (size 2-3) natural and human-triggered avalanches have released on this layer. Observations are concentrated to north, northeast, and east aspects near treeline. This problem has been observed in all but the northern tip of the region, where there is uncertainty around the distribution of this layer.
Rising temperatures and intense solar radiation is expected to initiate wet loose avalanches. This activity is likely to be most prominent on steep slopes that receive direct day-time solar radiation (slopes that face south through west). Although with above freezing temperatures, the problem could become more widespread. Minimize exposure to steep, sun-exposed slopes and cornices.

Around 60 to 80 cm of snow overlies a weak layer of surface hoar. This layer has been most problematic on northwest to northeast aspects between 1600 m and 2300 m, but it may exist on all aspects and at all elevations. Assess the layer prior to committing to avalanche terrain or adopt a conservative mindset to avoid the problem.
Strong solar radiation may trigger a natural wet loose avalanche cycle on steep solar aspects.
A weak layer of surface hoar is buried 50-100 cm deep. Past observations indicate the problem is most likely to be found on north, northeast, and east aspects near treeline. This problem has been observed in all but the northern tip of the region, where there is uncertainty around the distribution of this layer.

Weak facetted snow near the base of the snowpack continues to be a concern. Treat wind-scoured, rocky, shallow terrain as suspect and avoid big alpine slopes that are threatened by cornices overhead. Additionally a weak layer of surface hoar sits 50-100 cm deep, within the range for human-triggering.
Fresh storm slabs will likely be widespread and easy to trigger.
Storm slabs will likely continue to be reactive, especially in wind loaded areas.
torm slabs in motion may step down to deeper weak layers, resulting in large avalanches.
The new storm snow may show a poor bond to the variety of old snow surfaces its landing on. This may result in a reactive storm slab or small loose dry avalanches from steep terrain. Strong southwest winds may have formed deeper deposits on lee aspects building new and reactive wind slabs in the alpine and in \"alpine-like\" features near treeline, particularly where these slabs sit on top of a crust/facet layer from early November.
30 to 70 cm of storm snow fell across the region over the last few days. Careful with the new storm snow, especially at upper elevations. Large human triggered storm slabs remain likely. The new snow may be resting on surface hoar and facets which could set up a scenario where storm slabs remain surprisingly touchy.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"d6dhf","text":"
Above freezing temperatures may trigger loose wet avalanches. Pinwheeling and rollerballs are good indicators of this type of instability. Avoid steep slopes with saturated snow, as wet loose avalanches can be surprisingly destructive due to their higher density.
Periods of heavy snowfall combined with strong winds are expected to form reactive storm slabs. These slabs will be more sensitive to triggering and larger in size in areas where the wind has transported the snow into deeper, more cohesive drifts. Natural triggers from heavy snowfall, wind, and cornice falls are a concern with this rapid load.
ecent fresh snow and strong southwest winds have likely formed new wind slabs in lee terrain.
Storm slabs will be widespread and very reactive due to significant snow amounts and strong winds.
Wet loose avalanches will become increasingly likely as temperatures rise and the sun hits the snow.
Storm and wind slab problems likely exist at elevations above the rain crust. They are most concerning around Blue River and Valemount where 30+ cm of snow may sit above crusts and a widespread layer of large surface hoar. There was less snow in other areas, but strong wind would have left reactive slabs on wind-loaded slopes and on steep convexities.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":209,"length":12,"key":0}],"data":{}}],"entityMap":{"0":{"type":"LINK","mutab
10-20 cm of new snow Thursday night and Friday accompanied by strong wind from the southwest will build fresh storm slabs. They may be more reactive on leeward slopes (NE-SE)  where the wind has deposited deeper and stiffer slabs. Loose dry sluffing from steeper slopes and terrain features.
