Avalanche Problems

Wind Slabs

These hard windslabs are between 10 and 25cm deep. Any new snow may hide these windslabs that up until recently have been active. It may still be possible to trigger this layer in select features from a thin edge of the slab.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3

Deep Persistent Slabs

Although the forecasted precipitation didn't materialize, deep persistent slabs are still a concern. This condition represents low likelihood but high consequence situation. Be vigilant in terrain choices.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 3
