Avalanche Problems

Wind Slabs

Isolated wind slabs up to 100cm thick in the high alpine are still triggerable in steep terrain. Thinner snowpack areas on gully sidewalls and unsupported slopes will be most vulnerable.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 2 - 3

Cornices

Strong winds from earlier in the month have created large cornices on lee (mostly easterly) aspects. Several large cornice collapses have been observed over the past week. These cornices could be a big enough to trigger a deep slab.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 2 - 3
