Avalanche Problems

Wind Slabs

20-30 km W wind this week may form windslabs with new unconsolidated snow. Older windslabs in the alpine and at treeline may still be triggerable by riders, by their sensitivity is decreasing with cooler temps.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Loose Dry

Steep features with a hard bed surface may yield small dry loose avalanches triggerable by riders.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 1.5
