Avalanche Problems

Wind Slabs

Isolated soft slabs have developed in lee terrain near ridge tops.

Be cautious as you transition into wind affected terrain.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2

Persistent Slabs

Hard slabs from last weeks winds persist (beneath recent storm snow) in alpine and treeline terrain. These slabs are unreactive to skier triggering, but whomphing and compression tests in the moderate range are being observed on this layer.

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
