Avalanche control work on Monday proved that this layer is still touchy. Most avalanches scrubbed down to the October 26th facet crust or the ground. This layer needs time to adjust to the load and this problem will be around for some time.
The base of the snowpack is weak and facetted in shallow areas and will likely be for some time. The new snow in combination with a skier has the potential to overload this weakness.
Moderate SW winds and warming temps continue to add to the windslab problem.
The Dec. 11th layer of facets and surface hoar is buried more than a meter deep. This layer is strengthening but was active during the recent storm.
Continued moderate winds formed winds slabs in the alpine and exposed ares at tree line. Winds were out of the NE, reverse loading ridge tops where you may not expect to find regular wind slabs.
The November 21st interface may be the culprit for the skier accidental size 3.5 yesterday in Camp West. This problem woke up with the recent rapid loading from extreme winds, and significant new snow in January.
The Oct. 26 layer is still very active. Some large natural avalanches are still occurring and human triggering is likely. This layer needs time to adjust to the load and this problem will be around for some time.

The Dec. 11th layer of facets and surface hoar is buried more than a meter deep. This layer is strengthening but was active during the recent storm.
The Dec.10 layer of facets and some surface hoar are down 150+cm at treeline. There have been few observations from this deeper snowpack region as to the sensitivity of this layer, but recent avalanche control has seen deep propagations.
Continued snowfall, combined with mild temps, will have created soft storm slabs in many areas. In the region, storm slabs have been reactive and easily triggered by skiers. Be especially cautious in alpine areas, where it has buried windslabs.

Snow is forecasted for the next several days. Expect new snow to bond poorly causing loose avalanches in steep terrain. This problem will transition into a storm slab as snowfall amounts build up over the next 24hrs. Winds will increase snow loading.
35cm of storm snow has created a reactive storm slab problem. Another 35cm of snow is expected to fall by Saturday afternoon with strong winds. Rapid loading will turn these slabs into a widespread touchy problem where natural avalanches are certain.

No recent overnight cooling to help recovery. An inversion, layered around 2200-2300m may keep BTL cool overnight but not TL or above. This will mean a constant wet loose hazard, and exposure to BTL run outs should be carefully considered and limited
The upper snowpack is saturated with water, creating Wet Slabs which are failing on solar aspects, sometimes to ground. In shallow areas, these are failing on the basal layers and can move fast on the dryer, weak, facetted snow below.
Wind slabs formed on Thursday may still be reactive on shaded aspects at higher elevations.
There remains a concern for deep weak layers in thin snowpack areas. Warm temperatures and solar radiation have the potential to wake them up.
Rapidly warming daytime temperatures and high solar inputs are causing loose wet avalanches to start by mid morning. Some of these are running long distances or triggering slabs along the way. Avoid exposure to these slopes when they heat up.
Extended warm temperatures, solar radiation and buried weak layers are producing wet slab avalanches in all locations except high alpine, north (shady) aspects. The simple answer is to avoid all avalanche terrain until it cools and the snow freezes.
