Terrain and Travel Advice
- Make conservative terrain choices and avoid overhead hazard.
Problems
Deep Persistent Slabs
The bottom of the snow pack is inherently weak with well developed Facets and Depth Hoar. Avalanches initiating in the upper snowpack are likely to step down to this layer and gain significant mass.
Aspects: All aspects.
Elevations: Alpine, Treeline.

Expected Size
Wind Slabs
Winds have increased to moderate values from the southwest likely creating thin wind slab at ridge crest and exposed cross loaded terrain.
Aspects: North, North East, East, North West.
