Avalanche Problems

Wind Slabs

Moderate to strong winds earlier in the weak formed breakable to hard slabs in the alpine and open TL slopes. Watch for touchy thin slabs on convex rolls and areas of down flow winds. A skier was pushed by a small slide on Wed in cliff terrain.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Cornices

Cornices are large, and are unpredictable. Watch for these overhead hazards. Recent large cornice failures have not all produced slab avalanches. Hard masses of cornices have fallen as size 2.5 to 3.0 fast moving avalanches running onto fans.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 3
