Avalanche Problems

Wind Slabs

Strong westerly winds this week have created the potential for surface slabs over this heavier midpack. A small avalanche cycle of size 1.5 - 2 slabs ran from steep northeasterly alpine terrain.

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

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2

Deep Persistent Slabs

No real change in the base of the snowpack. The crust and facet layer is now buried a bit deeper, and will probably require a large load to trigger an avalanche. Don't be this trigger, as full depth, dangerous releases are still possible.

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 4
