Avalanche Problems

Storm Slabs

The Jan 30th interface has proven reactive with light inputs of new snow. This new storm will only continue to overload that layer. Also, treat recently re-loaded bed surfaces with caution as this layer will not go away easily.
Avoid all avalanche terrain.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Very Likely

Expected Size: 1 - 4

Deep Persistent Slabs

This layer remains a concern in isolated areas above treeline and may be triggered by large loads such as cornices, surface slides or from shallow areas by skiers. The entire snowpack throughout the forecast region is sitting on 20cm of depth hoar.
Avoid all avalanche terrain.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 4
