Avalanche Problems

Wind Slabs

Snow and wind loading with gusting winds created a wind slab hazard. The team has limited snowpack observations yet tests show the base is weak and the new snow interface is uncertain. Remain vigilant for reactive and changing conditions.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2
