Avalanche Summary

No new avalanches were observed.

Snowpack Summary

The warm temps and strong winds are creating widespread windslabs in the alpine and specific areas at treeline.  These slabs are 20-30cm thick and failing on weak facets and/or the December 15th interface.  The November crusts are still deeper down in the snowpack but they are facetting out more and more each day and have yet to produce a significant sheer during snowpack tests. 

Avalanche Problems

Wind Slabs

Widespread windslabs in Alpine terrain and specific areas at immediate  treeline such as gullied features. 
Carefully evaluate and use caution around thin snowpack areas.Avoid cross loaded features.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 3
