Avalanche Problems

Persistent Slabs

60 to 100 cm of recent storm snow lies overtop of basal facets. Natural avalanche activity has subsided. Whoomphing in the alpine indicate that the snowpack is still reactive to skier triggering and the potential for full depth releases still exist.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 2 - 3

Wind Slabs

High winds today have created fresh wind slabs on lee terrain. Suspect these slabs are reactive to skier triggering.

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

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 2 - 3
