Avalanche Problems

Storm Slabs

30-50 cm of storm snow has fallen in the past 48 hours. This storm snow in combination with strong southerly winds have created touchy avalanche conditions at the treeline and above elevations.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 2 - 3

Wind Slabs

Strong southerly winds associated with the recent storm has created widespread wind slab conditions in the alpine. These slabs are responsible for several natural avalanches observed today and are reactive to skier triggering.

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

Elevations: Alpine, Treeline.

Likelihood: Likely - Very Likely

Expected Size: 2 - 3
