Regions: Kananaskis.

The newly formed December Rain crust was found up to 2100ish today with powder snow above this.  We expect this height to be typical within the forecast region.

Avalanche Summary

No new avalanches were observed.

Snowpack Summary

Windslabs persist in Alpine terrain from the recent snows.  The newly formed Dec 6th Rain crust is being found up to 2100m and dry powder snow above this.  At the base of the snowpack, the problems associated with the basal weaknesses also persist.  These weaknesses include the 1106crust as well as the basal facets overlying this crust.  Some isolated surface facetting and isolated SH growth.

Avalanche Problems

Deep Persistent Slabs

Be cautions around thin snow pack areas
Be aware of the potential for full depth avalanches due to deeply buried weak layers.>Be aware of thin areas that may propogate to deeper instabilites.>

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 2 - 4

Wind Slabs

Thin new winslabs in Alpine terrain. 
Avoid freshly wind loaded features.>

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

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 1 - 3
