Not sure if I should say snow and wind, or wind and snow. But in either case, we will be getting both over the next few days. With warm snow and high winds, slabs will build quickly. Keep an eye (and ear) out for what's going on above you as you ski or climb.

Snowpack Summary
I feel like I've written this before...
The recent winds have caused some problems for our alpine and treeline snowpack. Windslabs of various thickness/hardness are basically everywhere, yet they seem to be variable enough to keep the skiing challenging. Treeline has an average depth of 80-100cm. The crust fades away above 2100m, but still offers a supportive midpack with no widespread failure layers.
Terrain and Travel
- Approach lee and cross-loaded slopes with caution.
- Watch for areas of hard wind slab on alpine features.
- Winter conditions may exist in gullies, alpine bowls, and around ridgelines.
- Ice climbers should be equipped with avalanche safety gear.
Problems
Wind Slabs
There will be several layers of windslabs on top of each other as this storm plays out. Within these layers there will likely be a weak, reactive layer to watch for.
Aspects: All aspects.
Elevations: Alpine, Treeline.
