Timing, track, or intensity of incoming weather system is uncertain on Wednesday

Avalanche Problems

Wind Slabs

Variable windslabs continue to develop from moderate-strong gusting winds. These slabs appear unreactive with relatively little natural activity yet assume touchy pockets exist such as steep gullies or unsupported slopes. Choose conservative tracks.

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

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 3

Deep Persistent Slabs

On Sunday, large cornice drops triggered this layer proving the lurking danger of this weakness. Full path avalanches remain possible. Caution initiating the windslab problem that could step down.

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

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 2 - 4
