Summary

Problems

Wind Slabs

An icon showing Wind Slabs
Breakable to hard slabs have formed in the alpine and open TL slopes. Watch for thin slabs on convex rolls and areas with down flow winds. Also some reverse loading has occurred from NE winds. A skier was pushed by a slide on Wed in cliff terrain.

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Cornices
