Avalanche Problems

Wind Slabs

No recent slab avalanche activity has been observed. Slabs are primarily present on NE slopes. Steeper slopes should be avoided.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 3

Loose Wet

Warmer overnight temperatures are forecast along with 5 - 10 cm on snow. This new snow will insulate our warm snowpack preserving isothermal conditions. Cloudy skies are also forecast which should limit activity on this weakness.

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

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 1 - 2

Deep Persistent Slabs

This layer is now buried by a settled upper snowpack. Triggering of this layer is still possible especially from a thin spot.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 4
