Snowpack Summary
Strong westerly winds have moved last weeks storm snow and blew away much of the surface hoar in the alpine. Generally, the snowpack is thin and wind-scoured with a thin suncrust on south and west aspects. The bottom of the snowpack consists of weak basal facets and a spotty melt-freeze crust from late October.
The snowpack is 30-50 cm deep at treeline with many areas still below threshold, and up to 90 cm in deeper alpine areas.
Weather Summary
Light flurries along the Eastern slopes Wednesday night with little to no accumulation. Winds will remain light and variable through Thursday with temperatures around -10C. . In the Northern region, a alpine inversion may set up, with slightly warmer temperatures up high, for the next few days.

Terrain and Travel Advice
- Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
Problems
Deep Persistent Slabs
The snowpack is very thin in most areas, but we have seen regular avalanche activity from areas that have enough snow cover over the last week. The base of the snowpack is very weak, if you are in terrain where the wind has created a dense slab on top of this weak base, be wary!
