Avalanche Problems

Wind Slabs

A return to seasonal temperatures and light winds should allow windslabs to begin to bond with the older snow surface. Skier triggering is still possible on lenses of windslab.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3

Deep Persistent Slabs

Large avalanches could occur where smaller avalanches or cornice failures trigger a collapse in deep basal facets. A strong midpack is bridging this layer, except near wind exposed terrain.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 2 - 4
