Wind Slabs
We have very few observations from the alpine, but suspect there may be some thin windslabs in the immediate lee of features. Watch for reverse windloading on features from the recent East winds.
Aspects: North, North East, East, South East.
Elevations: Alpine.
Likelihood
Expected Size
Persistent Slabs
There is 20-40 cm of light density storm snow on the supportive Nov 6 raincrust. Generally bonding well to the crust now, except in a few select areas where the local wind has created a slab. See our NEW AVALANCHE OBSERVATION tab for more details!
Aspects: All aspects.
