Avalanche Problems

Storm Slabs

Gusty and variable winds have formed storm slabs on all aspects at upper elevations, especially in exposed areas. A widespread natural cycle was observed on Thursday, and explosive control work produced numerous avalanches to size 2.5.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Very Likely

Expected Size: 1 - 3

Wind Slabs

The recent storm snow sits on previous wind slabs on lee features and has the potential to produce large avalanches if triggered.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 4
