This is sitting on a crust that was buried wet I think. The snow on top was only 15cm deep so with the cold weather there may be some facetting happening to this layer in the next few weeks. possibly some reverse loading with change to n'ly flow but isolated to ridgecrest
Isolated pockets of WS remain on NW to NE aspects. Potential for triggering remains on very steep 40+ terrain.
Isolated pockets of WS in Alp. Concern on unsupported 40+ degree terrain.
Mostly soft slabs but may become hard slabs with north winds and reverse loading.
Wind slabs becoming less of a concern with cold temps and little wind. Slab loosing energy.

Reverse loading w/ outflow winds. Wind slabs forming on a sun crust on southerly aspects, may be touchy.
Reverse loading hasn't happened yet. Slabs are hidden with dusting of new snow. This is sitting on a crust that was buried wet. I think snow on top was only 15cm deep so with the cold weather there may be some facetting happening to this layer in the next few weeks.
Reverse loading with L-Mod Northerly winds. The question remains as to the direction of the wind (N, NW, or NE) and how much snow is available for transport.
Light to Moderate winds from the N, NE, and E producing thin soft slabs on S, SW and W slopes. Slabs formed previously on N, and NW slopes sitting on a crust buried wet remain a question in isolated areas. Continued faceting with cold temps on this interface. May be less sitting on this now with outflow winds.
Reverse loading with Mod-str NE, E winds continues to strip ridgecrests and load alpine lees. Isolated HSL and SSL on W, SW, S asps. Cooler temps helping with the bond between windslabs and old sfc  in short term.
Continued Moderate to Strong N, NE, E winds forming isolated HSL and SSL. Windslabs sitting on crust. Cold temps continuing to facet this interface.
cold temps promoting the bond between the current windslabs and old snow surface. Isolated HSL in locations with high consequence with even a small release. ie. extreme terrain
Windslabs previously formed in alpine lees. Question as to the bond between slabs and old snow surface. Temps seem to be staying cool up there. Although a blip of an above freezing layer.

I would be more concerned by cornice failures, and steep rocky features or where winds have formed a local slab
I think I'd change this to a persistent slab, around the clock, all elevations next time we re-write this forecast. Perhaps more along the lines of what I did for S Columbia today?
Fracture character is mainly resistant in S2S and Duffy. Much less deep in east Duffy.
Sensitive to ski testing on Saturday (2x size 1 HSL). Becoming less sensitive as the temp cools and winds ease off on Monday.
PWL is down 90cm in Lizard. Very uncertain in the Crowsnest (not much data). No new avalanches.
Distribution of SH is spotty and in sheltered areas near TL. Maybe a few pockets up higher. It is still worth noting in the forecast.
Outflow warning continues in coastal areas
VEry iso pockets. Old slab from S'ly and W'ly winds. New slabs from N'ly with arctic front coming through.
Uncertain how the WS development played out.
Isolated pockets of wind slab from Arctic winds forming on west and south facing terrain.
Pockets of wind slab resulting from easterly winds. These slabs may remain a concern until Friday.
SH might be buried under WSL in isolated locations below ridgelines.
The windslab problem is not a huge problem right now but if the weather forecast is accurate they will likely develop at/near ridgecrest as temps warm and winds pick up. A bit of new snow will be a lesser contibuting factor. Areas that get more new snow and warming (e.g. west slopes of westerly and northerly ranges) might be a bit worse in the north than in the south.
Warming temps and moderate winds are creating ssl in the Selkirks and hsl in the Purcells at ridgecrests. Windslabs reported to be reactive to skier traffic. Strong S winds Fx will further slab dvlpt.

Isolated pockets of small SH 091228 in lower alp. Variability across the region on this layer is significant.
The Dec 29 SH appears to be a non-issue in the Cariboo and Monashee Mountain ranges. I still have a bit of reservation on Jan 29 about the SH in the N. Selkirks in the lower alpine (200m of TL) and TL.
Increase in the propagation behavior over the last 7 days in the Purcells and Selkirks, no issue in the Monashee. Wide propagation now being reported in some areas not previously experiencing this type of behavior.

Down 60cm in a 120cm snowpack. Only in the big open bowls or gullies, hard slab on top.
Pretty much a non issue expect for the really exposed big stuff in the Alp. Even then most slabs have stabilized.
In general, it appears that the surface hoar is more of an issue in the Purcells at all elevations that the Selkirks or Monashee Mountain ranges. There was a steady string of skier triggered slides near Kicking Horse Mountain Resort. Looks like this has died off.

minor sluffing, not a primary concern in bulletin
Some locations still reporting sudden planar results- eg.Baldface. I imagine it to be a very spotty issue. More concern where the slab on top of it is still only 60cm thick.
The snowpack on the eastside is very thin this season so pretty weak snowpack overall. Needs more load to be a real hazard.
Snowpack results vary from hard SP or RP to no results. Depths vary from 60-120cm deep. I imagine it to be a very spotty issue. More concern where the slab on top of it is still only 60-70cm thick.
Unreactive but still mentioned by some operators. Step down potential as the mass of the surface slab increases.
NEH: concern remains for 100126 and 100128 SH down 50 and 70 cm respectively.

Still only 90cm down- well preserved crystals giving sudden planar results. I suspect skier triggering still a possibility, but only in steep low alpine convex features especially where snowpack is a bit shallower.
Acting like a deep slab. We receive occasional reports of avalanches on the SH layers from the Columbia's.

Only a concern with terrain traps in the runout
As more new snow slowly accumulates. Only a problem above terrain traps. Not enough mass yet for further concern.
This may initially be more of a loose dry snow problem. As the load incrementally increases and settles at the same time it will be more of a storm slab problem.
Slab formation is likely today under milder conditions and continued snowfall.
Slow accumulation in cool temps, no slab yet.

High winds accompanying the recent snowfall will have produced wind slabs at tree line and above. Use caution venturing into wind loaded lee slopes
Touchy storm slabs exist with the potential to create large avalanches. Storm slabs may be more reactive on slopes affected by wind, or in areas where they overlie surface hoar. Sluffing may also occur where new snow is unconsolidated.
Loading from the recent storm may reactivate persistent weaknesses buried in the mid and lower snowpack. If triggered, avalanches on these layers would be large and destructive.

Sluffing is occurring in steep Alpine terrain.
New wind slabs may form on South and West aspects at all elevations in response to strong outflow winds this week. It may also be possible to trigger older wind slabs on exposed North and East aspects near ridgetop.
New storm snow may not bond well to the underlying surface, which may include surface hoar or a sun crust. Strong northerly winds may form touchy new wind slabs in exposed South to West facing terrain.

Strong and variable winds have formed touchy wind slabs on a variety of aspects in exposed terrain. Outflow winds this week could redistribute new snow and create dense wind slabs on West and South aspects.
Suspect that there is a touchy to very touchy storm slab above the recent surface weakness. No information about how deep this storm slab is or how variable it is.
Deep storm slabs are releasing naturally from steep terrain, and are very easy to trigger on all aspects and at all elevations. Triggering slopes from adjacent terrain is a concern due to the buried surface hoar and crusts beneath the storm snow.
The new storm slab may be up to 50 cm deep in some parts of the region. This storm slab may release naturally, or be triggered by light additional loads like skiers/riders. Travel on adjacent terrain may trigger avalanches.

Storm slabs may continue to be triggered by human activity where the new snow is sitting on a weak layer that was recently buried. Storm snow slabs are up to 70 cm deep and may result in large avalanches if triggered.
The deeply buried early season crust may be reactive to the added load of storm snow, the weight of large triggers like snowmobiles or a group of skiers, or from storm snow avalanches in motion.
Storm snow avalanches are becoming more stubborn to trigger. As the storm snow settles into a cohesive slab or is transported into a wind slab, wider fracture propagations resulting in larger avalanches are a concern.
A settling storm slab overlies various buried weaknesses; surface hoar on shaded slopes and and a melt-freeze crust on solar facing slopes. In areas where the surface hoar overlies a thin melt-freeze crust the slab above may be particularly touchy.
The recent storm snow has been redistributed by northerly winds into wind slabs on south facing slopes. Cold temperatures may allow these wind slabs to persist.

Ongoing snowfall, wind and moderate temperatures have added to a developing storm slab problem. Watch for increased reactivity in wind-affected terrain or at elevations where the upper snowpack has been affected by warming.
Use increased caution in wind-loaded areas. Recent westerly winds will form soft slabs at alpine and treeline elevations. In areas which received less new snow or where the snow has yet to settle into a slab, the hazard may be lower.
Recent precipitation with strong winds has created storm slabs at tree line and above. Lower elevation snowpack is likely saturated with rain. These wind slabs&nbsp; will take time to bond, but cool air later in the week will reduce the hazard.
10 to 30 cm of wind and storm slabs now sit atop the surface hoar and facets from the early Dec. arctic cold snap. Reports indicate that these surface slabs are now becoming reactive. Shallow snowpack areas may be more easily triggered.
Recent snowfall accompanied by high winds has created winds slabs on lee slopes. It will take time for these slabs to bond to the existing snowpack. The areas of major concern are at tree line and above.
The new denser storm and wind slabs are sitting above a weak layer from the cold snap in December. It will take time for these layers to bond. The surface slabs may become easily triggered with increasing snow load.
Recent snow and strong to extreme SW winds have created storm slabs at all elevations. These slabs are increasingly touchy especially at higher elevations, and are expected to get more pronounced with the incoming storm.
Avalanches could step down to the October crust (or the ground) and involve the entire winters snowpack, especially in shallow snowpack areas.
The combination of new snow and very strong W-SW winds on Tuesday will likely form touchy new wind slabs in exposed lee terrain well into treeline. 
Forecast strong or extreme westerly winds may create new wind slabs in exposed lee terrain and cross-loaded features at and above treeline. 
The late November surface hoar layer, now down 40-50 cm, may become more reactive with mild temperatures and continued loading.
Forecast new snow and strong to extreme westerly winds will likely create dense new wind slabs in exposed lee terrain at all elevations. These wind slabs may release naturally in specific areas.
Continued loading and mild temperatures could make buried persistent weaknesses in the upper and mid snowpack much more reactive. Make conservative terrain choices over the next couple days.
Another 20-25 cm of snow is possible through Tuesday, with strong to extreme westerly winds. Expect dense wind slabs in exposed lee terrain well into treeline. These weak wind slabs could fail naturally in specific features.
Continued loading and mild temperatures may increase the reactivity of an assortment of persistent weaknesses buried in the mid and upper snowpack. Triggering a persistent slab may have nasty consequences.
Wind and storm slabs overlie the sugary faceted snow that formed in early December. Several size 1 skier controlled slab avalanches have been reported in the last few days.
The concerns at this time are wind loaded areas at tree line and above.  The more dense wind loaded snow may not be well bonded to the facetted snow underneath, and may be highly reactive to skier or sled loading.
Recent strong SW winds have created winds slabs in leeward features
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.

Forecasted strong winds from the SW tomorrow and snow available for transport in the alpine and top treeline will keep loading lee slopes. Storm snow in sheltered areas and fresh windslabs could weaken with the warming temperatures.
Facet/crust combo down 100 cm is still a concern mostly at treeline.
North of Steward, storm slab and wind slabs on NE facing slopes will keep developing . South of Steward, windslabs will be the main concern.
The facet/crust or surface hoar down 100 cm and the basal facets layers are gaining strength but could still be triggered by a heavier load such as a cornice fall or a windslab avalanche stepping down.
Widespread and rapid propagation of the surface windslabs was observed during avalanche control work on Thursday.&nbsp;
Avalanche control work and natural avalanche activity observations highlight the deep weakness - natural avalanche observations and avalanche control work&nbsp; consistently saw failures occurring at the base of the snowpack&nbsp; producing large avalanches.
Recent storm snow has been transported into wind slabs at higher elevations. Some areas may have wind slabs that are about one metre thick. Very warm alpine temperatures may result in loose wet avalanches on southerly aspects, or cornice falls.
Recent storm snow may not be bonding to the surface hoar and melt-freeze crusts that developed before the storm. Storm slabs are more likely in areas sheltered from the recent strong winds. Forecast warm temperatures may result in easier triggering.
Very strong winds have created hard wind slabs in the alpine and at treeline. These hard wind slabs may be more than a metre thick. Forecast very warm temperatures and strong solar radiation may increase the likelihood of triggering.
Warming and solar radiation will weaken snowpack and cornices. A loose or slab avalanche or cornice drop could trigger this deeper instability.
Beware of loose wet avalanches especially on S and SE aspects. Steep crossloaded or lee windloaded areas could become unstable tomorrow especially if the sun hits them.
The basal facets layers are gaining strength in the S part of the region but are still reactive in the N. Warming and solar radiation will weaken the snowpack and cornices. Wet loose, slab avalanche or cornice drop could trigger this very deep layer.
The settling storm snow and windslabs could weaken tomorrow especially if they get strong solar radiation tomorrow. Expect loose wet avalanches especially on S and SE aspects.
Forecast warming will increase the likelihood of triggering a number of persistent weaknesses which exist in the snowpack. Triggers include cornice fall or a surface avalanche in motion. Any persistent slab avalanche would be highly destructive.
Although recently formed windslabs may be gaining some strength, they may still be triggered in steep, unsupported terrain. Watch for increased triggering with forecast warming.
Several deep and destructive avalanches have failed at ground level over the past few weeks. Forecast warming will promote ongoing activity at this interface with the potential for very large avalanches.
Recent storm slabs have most likely gained strength. Triggering may be more likely on steep terrain where the new snow exists as a wind slab, where it overlies recently buried surface hoar, or on sun-exposed slopes.
Forecast warming will increase the likelihood of triggering a number of persistent weaknesses in the snowpack. Possible triggers include cornice fall. A persistent slab avalanche would be highly destructive in nature.
Recent new snow with extreme winds has overloaded the snowpack on most N and E aspects. Where fresh pockets of new snow and wind slab remain, consider them to still be touchy.
Weak sugary facets and depth hoar at the base of the snowpack are most prevalent in the Powder Valley and Wheaton Valley areas. Recent avalanche activity has confirmed this has the potential to release large avalanches.
Forecast warming will increase the likelihood of triggering a number of persistent weaknesses which exist in the snowpack. Triggers include cornice fall or a surface avalanche in motion. Any persistent slab avalanche would have nasty consequences.
Wind slabs which formed a few days ago may be gaining some strength; although triggering remains a possibility in steep, unsupported terrain.

Windslabs are beginning to settle out and strengthen but they are still a problem.  Be careful as you transition into more open wind affected terrain.
This layer came to life during the recent avalanche cycle and many large events were observed on this layer.&nbsp; Any avalanche in the upper snowpack may step down to the basal facets so be thinking about large avalanches as you travel.
Hard wind slabs exists in many areas throughout the region. Although they have gained considerable strength, triggering is possible in unsupported terrain, on sun-exposed slopes, or in areas where they overlie persistent weaknesses.
Continued warming will increase the likelihood of triggering a number of persistent weaknesses which exist in the snowpack. Triggers may include cornice fall or a surface avalanche in motion. Any persistent slab avalanche would be highly destructive.
Recently formed windslabs have likely gained significant strength; although triggering may be possible in steep, unsupported terrain. Watch for increased triggering with forecast warming.
Storm snow has been transported into thick pockets of wind slab, reported to be stubborn to trigger. Storm slabs linger in areas sheltered from the wind, and may be triggered by skiers and riders in steep terrain.
Deeply buried weak layers may exist near the ground. This is more likely in areas that had a shallow snowpack during the cold arctic outbreak.

A weak layer of facets/depth hoar at the base of the snowpack has been responsible for some recent very large avalanches. The likelihood of triggering this layer is now considerably reduced, but the consequences associated with this layer are huge.
New snow and wind will likely set up reactive slabs, especially in lee and cross-loaded terrain in the alpine. Given the recent history of large avalanches, there is a chance that a small avalanche triggered near the surface could step down.

Wind slabs up to 40cm thick are being encountered in immediate lees along ridge lines and in cross loaded features. Most of the recent natural avalanche activity has been obs in Alpine.
Avalanches are often stepping down to the basal October layers and involving the entire winters snowpack. In some areas a dense wind slab overlies this deeply buried weak layer, so the possibility for large and destructive avalanches exists.

Forecast strong to extreme southwest winds will likely add fresh wind slabs on north through east facing terrain. Expect particularly touchy conditions where wind slabs sits on top of recently buried rain/melt-freeze crust(s).
Strong winds have transformed the alpine, creating variable, shallow conditions. In shallow, rocky areas, the weight of a rider may be more susceptible to trigger this deeper layer. This problem is most prevalent in the Powder and Wheaton Valley.

These slabs are more of a problem as the winds pick up and become more sustained. The propagations have been larger today than previous days, and sensitivity is going up as well. Avoid any windloaded areas at treeline and alpine.
Thin rocky areas are still the likely trigger point. There has been no activity seen on this layer, but the potential is still there. Stepping down may become a concern as the wind slab avalanches grow in size.

Forecast new snow and strong winds are expected to add yet another incremental load to the snowpack. Weak layers within the storm snow may be found from temperature changes and/or wind events. Long propagations and remote triggering may be likely.
There are several buried crusts and or surface hoar layers that developed in the end of January and during the cold weather earlier this month. Avalanches releasing on these layers may be large with serious consequences.
Forecast new snow and strong winds are expected to add to the load above the weak layers. Weak bonds may exist within the storm slab due to changing temperatures and wind events between storms.
I am splitting this PWL out of the storm slab problem because most of the activity is releasing in the storm snow layers. Avalanches that release on this PWL are expected to be less frequent but higher consequence.
Forecast new snow and strong winds are expected to continue to add a new load to the storm slab. Natural avalanches and very touchy sensitivity to human triggers may result from this added load.

The basal weakness remains, and incoming snow and wind may lead to a re-awakening of this problem.
Close to a metre of highly reactive storm slab is now sitting on a variety of weak layers, facets, surface hoar and decomposed wind slab. Significant potential for remotely triggering an avalanche below or adjacent to start zones exists.
Up to 60cm of storm snow has settled into a reactive storm slab that lies over a combination of surface hoar, facets, and wind slabs. Wind slabs above and below tree line are a major concern. Remote triggering is probable in even moderate terrain.

Wind has transported snow and built touchy wind slabs on the leeward side of terrain features. Be aware of weak cornices looming over slopes.
The Feb 10 persistent weak layer is highly variable in nature (a mix of facets, sun crust, wind slab, surface hoar) and is still producing moderate to hard shears down 35 to 70cm in the snowpack. Isolated whumpfing and cracking continues.
Surface hoar and facets sitting on a crust is likely down close to a metre in wind-loaded alpine start zones and remains a concern primarily in the South (near the Alaska border) where a thicker, more cohesive slab overlies.

The new snow may not bond well to the previous snow surface. Expect deep wind slabs to build in exposed North through East facing terrain at and above treeline, and the potential for wet slab or wet loose avalanches below treeline.
Strong S-SW winds will likely build new dense wind slabs, while old hard wind slabs may be lurking on south and east aspects. A relatively thin wind slab could step down to the deeper mid February persistent weak layer.
New loading from snow and wind or rising temperatures could create a cohesive slab over this persistent weakness, down around 30-80 cm deep, and increase the odds of triggering this problem.
Ongoing persistent avalanche activity proves layers formed about a month ago deserve respect and should still be in the front of your mind. Storm slab avalanches in motion or cornice falls may trigger the persistent weak layer.
Forecast new snow and wind is expected to add an additional load to the recent storm slab that may not be well bonded to the old surfaces.
Warm temperatures are encouraging the settlement of the storm snow into a  soft slab that overlies a variety of potentially weak surfaces. Moderate to strong SW winds have formed stiff wind slabs in lee features.
The early Feb weak layer still remains reactive in some areas and has the potential to produce large, destructive avalanches. Warm temperatures and the load of the new snow may 'wake up' this weak layer and very large natural avalanches are possible.
Forecast heavy precipitation will continue to to load the melt-freeze crust buried in early March.
Heavy loading could be enough to trigger the mid-February facet/crust combo, particularly on northerly aspects. Step down avalanche are possible.

Wind slabs are likely to exist on a variety of aspects and rider triggering is possible in the lee of ridges and terrain breaks.
Recent observations suggest wind slabs may still be reactive to the weight of a skier. Watch for triggering in gullies and in the lee of ridges crests.
Persistent weaknesses buried in November remain a concern for professionals in the region. Watch for shallow snowpack trigger points on steep, unsupported slopes.
The consistently warm temps are preserving the midpack right now. The mid layers are what's keeping the hazard at a moderate level. Before committing to bigger terrain, assess these layers and be sure the strength is there.
New snow is likely to sluff readily above a crust on steep terrain.
Winds are expected to be at the ideal strength to transport the low density snow that lies on the surface and set up thin but touchy wind slabs.

Forecast new snow and strong winds are expected to start to develop a new storm slab in the alpine and at treeline. Early in the storm the new snow may release as loose dry snow and slide easily on the old hard crust or surface hoar interface.
A new storm slab is expected to develop over the next few days as forecast snow and wind move into the region from the coast. Recent windslabs may be difficult to locate due to the new snow. Some loose dry snow may slide easily off of the old crust.
This is still the main concern right now. Choose terrain that is supported and in a deeper snowpack. We are definitely dealing with a classic Rockies snowpack right now!
