Mostly soft slabs but may become hard slabs with north winds and reverse loading.
KHMR Patrol mentioning that the FC / CR is breaking down. Uncertain of propagation propensity at TL, but suspect it could zipper further than expected.
buried HSL, fresh SSL
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.
Isolated pockets of windslab on southerly aspects from reverse loading and cross loading. Concern on 35+ degree terrain.

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 M-S outflow winds. Windslabs building in the lees of localized terrain features. 25-30 sitting on 091203 SH.
Reverse loading with Mod-Str NE, E winds continues to strip and load. Isolated HSL and SSL on W, SW, S asps. Cooler temps helping with the bond between windslabs and old sfc  in short term.
Loading pockets @TL
Continued reverse loading with outflow winds. 25-30 sitting on 091203 SH. Warmer temps approaching 0 degrees at TL Monday could be a short term factor for the bond between windslabs and old snow sfc.

SH reactive. Snow starting to bond to CR on south / southwest. Fatal avalanche yesterday within the BRC tenure. Private party. Limited details at this time.
Widespread condition but variable distribution. Most prominent in sheltered, shaded areas. Seems more of a problem in Selkirks and Monashees, not so bad in Cariboos--yet. I am leaning to high danger for Selkirks/Monashees at the treeline elevation band even though I know that by the letter of the definition it's probably Considerable.

Very much like N Columbia.
Very isolated distribution, widespread whumpfing in Coq Pass area yesterday, reactivity could pick up with Fx loading and warming.

Mostly a concern where a solid crust is just below the  surface
We are still concerned about this layer (GJ / DM). In spite of indications it is settling down a bit and propagation are decreasing, I worry that perhaps we are not getting the full picture: that is, have folks identified problem areas and are now staying away from them and/or is use being concentrated in areas with compaction? Certainly that's what I'd be doing if if were out there.
Storm pattern just firing up, load will increase. Step down potential to Dec 16.
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.
Primarily in Lizard Range. Contd reports from Fernie ski tourers of Sr-Sa 1-1.5 on steep convex rolls @TL, fast moving. Stab results indicate propagation propensity decreasing.

Storm slab formation is ongoing. Up to 25cm of recent snow has fallen and winds are strong from the SW. Stability tests today indicate that the storm slabs are getting easier to trigger, particularly in the Alpine.
Pockets of buried wind slab are present in lee and cross loaded features in the alpine and isolated areas at tree line. These weakness are harder to locate with the new snow.
The Nov rain crust persists about 30cm off the ground throughout the forecast area and is reactive to stability tests in the hard range. Avalanches in the upper snowpack may step down to this weakness.
="s_3FE45715">Continued snow and wind may overload a weak layer of surface hoar and/or a crust, now down 30-50 cm. The size and likelihood of avalanches should increase throughout the forecast period.
Although the likelihood of a release is low, the consequences of a persistent slab avalanche could be significant. These layers may wake-up with additional loading.

Continued light snowfall with moderate SW winds will add to the wind slab problem.  These slabs range from 20 cm in the North to 60 cm in the South of the region.  They may be sensitive to the weight of a sled or skier.

Fresh sensitive wind slabs continue to build at and above treeline.&nbsp; They're found immediately below ridgecrest and in the lee of mid slope terrain features.  These slabs may be sensitive to the weight of a skier or rider.
Sustained wind and snow continue to build touchy slabs which could be triggered naturally, or by the weight of a person, especially in steep terrain.

Light amounts of new snow have been redistributed by strong winds into wind slabs on a variety of aspects. These wind slabs are adding to older storm snow accumulations which have most likely gained considerable strength.
A persistent weak layer of surface hoar, buried 60-80 cm below the surface has been reported from around Shames. Although triggering seems less likely, watch for convex rolls in sheltered areas where the SH may have been preserved.
Deeply buried weaknesses exist. Large triggers, such as cornice falls, could release deeper avalanches on steep, smooth terrain, especially in thinner snowpack areas.

With slightly warmer temperatures, the new storm may develop a denser surface slab. Recent light snow may also be transported by forecast strong southwest winds into deep wind slabs on north through east aspects.
Loose dry snow remains unconsolidated in terrain that is protected from the wind. There is a lot of new snow; sluffing may entrain enough snow to bury a skier/rider.
="s_3FE45715">The new storm is expected to develop a storm slab on all aspects. The forecast strong SW winds may transport storm snow into thick and touchy slabs on north through east aspects.
Previously formed wind slabs are highly variable in their depth and distribution, but are prominent in alpine areas and isolated locations at treeline. These slabs are now hidden by new snow, so dig down to confirm or deny their existence.
The Nov rain crust is still in the back of our mind. Although field tests are not producing concerning results, shallow snowpack areas are still a possible triggering point for this deep layer.

25cm of recent storm snow with strong to extreme W and NW winds have created storm slabs at all elevations. Cracking was observed in the alpine today and these slabs will become increasingly sensitive to human triggering over the next couple of days.
Steep terrain on all aspects are producing loose dry avalanches up to size 2.0. Occasionally these slides are also triggering small slabs. This is of particular concern in terrain traps. Ice climbers and skiers should be aware of overhead terrain.
Recent test results show the Nov rain crust to be generally unreactive, but this could change with the addition of new snow load over the next several days. Carefully evaluate shallow snowpack areas.

Windslabs are expected to keep forming on leeward slopes which could lead to natural avalanches. The storm snow in more sheltered areas will still need some time to settle and could be still touchy.
An avalanche triggered in the new snow or new windslab could step down to a persistent weakness in the snowpack buried down 100 cm.
The storm snow in conjunction with strong NW winds will likely continue to overload weak layers in the upper meter of the snowpack. Many slopes are primed for human triggered avalanches, particularly on exposed lee aspects at and above treeline.

Some natural activity noted today in the alpine. Generally the new snow is still unaffected by the light winds. As the winds pick up this problem will become more of a concern. Immediate lee features are of particular concern.
Triggering of this layer may be from a thin, weak area or from a smaller avalanche over whelming the strength of the midpack and stepping down. Large terrain features remain suspect. Full depth avalanches are still very possible.
The lack of wind is keeping this problem on the radar. In particular, gullies and steep cliffs are a concern. Ice climbers be aware of your position in the terrain and how it may effect you.

These are becoming more substantial with the wind transport and cooler temps. Watch for them as you approach open areas at treeline.
Our comfort level with this layer is still not good. The cycles that have been ongoing suggest we are at the &quot;human trigger&quot; phase of the cycle. Avoid large slopes, overhead slopes, convex slopes and any area that has not avalanched. 
A weak facet/crust combo, with surface hoar in some areas, is now down 80-150 cm and remains a concern for human triggering. This weakness shows potential for wide propagation and very large avalanches.
Previous strong southerly winds created dense wind slabs in exposed lee terrain. These wind slabs are likely buried by low density new snow.
A persistent weakness, now down 60-80 cm in the northern part of the region and 100-150 cm in the south, remains a concern for rider triggering. This tricky problem has the potential for wide propagation and very large avalanches.
Previous strong winds formed wind slabs in lee and cross-loaded terrain, which may now be covered by up to 20 cm of low density new snow.
Blue skies and fresh snow will make it very tempting to push out into more committing terrain. Don't get lured in! The current conditions are very tricky and require patience and conservative decision making.
Outflow winds have likely created new dense wind slabs in exposed south and west facing terrain at all elevations. Older wind slabs may still ne lurking in north and west facing terrain.
Solar radiation and/or additional wind loading could be enough to tip the scales and greatly increase the potential for triggering this problem. Pay close attention to local conditions.
Outflow winds may have redistributed some of the recent storm snow and formed dense wind slabs in unusual places.&nbsp;

Continued cold temperatures are expected to preserve the buried February weak layer of facets and crusts. Avalanche fractures may propagate further if the old storm snow above the weak layers settles into a cohesive slab.
Continued strong Easterly winds are expected to scour leeward slopes and develop hard wind slabs in areas that have snow available for transport.
New storm snow sits on top of a hard crust layer.&nbsp; Strong SW winds will create wind slabs in leeward and cross-loaded features.&nbsp; Wind slabs and loose dry avalanches are expected to be the primary problems for Sunday as the storm begins.

This problem remains very persistent and still has the potential to produce large, destructive avalanches.&nbsp; Human triggering is becoming more difficult in thicker snowpack areas but can still be easily triggered in thin spots or with heavier triggers&nbsp;
Recent wind from the north has formed wind slabs on lee features.&nbsp; This is the opposite loading pattern than normal so use increased caution in wind-affected terrain.&nbsp; Fx winds for Sunday are moderate-strong from the SW and will form new wind slabs.
Expect the buried persistent weak layer to continue to produce large and destructive avalanches. Many slopes are still primed for human triggering and remain a concern on all aspects and elevations.
Older wind slabs still exist in many lee terrain features but are becoming harder to trigger. New wind slabs are expected to form as wind increases on Sunday. Weak cornices also remain a concern in isolated areas.
North aspects in the alpine are the most likely slopes for human triggering the February weak layer. Avalanches releasing on this deeply buried persistent weak layer my be large and destructive.

Expect the deeply buried weak layer to continue to produce large and destructive avalanches. Many slopes are still primed for human triggering and remain a concern on all aspects and elevations.
Recent strong winds plus more strong wind in the forecast will continue to load leeward and cross-loaded features.&nbsp; Expect these winds slabs to increase in size as new snow accumulates on Sunday.
Human triggering with the possibility of long fracture propagation resulting in very large avalanches continues to be a concern. North aspects in the alpine may be the most suspect slopes.
Forecast new snow and wind are expected to develop a new storm slab that may not bond well to the mix of old surfaces.

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 shears down 30 to 60cm in the snowpack. Isolated whumpfing and cracking continues to occur on this layer.
Storm slabs will develop tonight and through the day Monday with the incoming snowfall and strong SW winds. Lee loading is expected to steadily increase over the next 48hrs especially immediately below ridge lines.
