Wind Slabs

No recent slab avalanche activity has been observed. Slab conditions on steeper slopes should be avoided.

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

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1 - 3

Loose Wet

Cooler overnight temperatures may strengthen the surface melt freeze crust but expect this to weaken as temperatures increase through the day. Cloudy skies should limit avalanche activity on this weakness.

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

Elevations: Alpine.

Likelihood

Possible

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

Unlikely - Possible

Expected Size
