Avalanche Summary
No recent avalanche activity has been reported.
We anticipate natural avalanche activity to occur with the arrival of strong winds and new snow.
Snowpack Summary
Expect widespread wind-affected snow surfaces, including firm, scoured surfaces in windward-facing terrain and deeper deposits around ridgelines and on lee terrain.
A layer of weak, faceted crystals overlying a crust is buried 30-60 cm in the east of the region and 50-100 cm in the west. Triggering this layer has become unlikely, except in the case of shallow snowpack spots or very large loads like cornice falls.

Terrain and Travel Advice
- Wind slabs are most reactive during their formation.
- Closely monitor how the new snow is bonding to the old surface.
- Start with conservative lines and watch for clues of instability.
