Avalanche Problems

Wind Slabs

Watch for new windslabs developing with NE winds, and old windslabs on all aspects.
Use caution in lee areas. Recent wind loading has created wind slabs.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2

Deep Persistent Slabs

The basal weaknesses are well bridged in deeper snowpack areas, but there remains the possibility to be surprised in thin snowpack areas.
Avoid thin, rocky or unsupported slopes.Avoid steep convexities or areas with a thin or variable snowpack.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 2.5
