Avalanche Problems
Wind Slabs
Not much has changed over the last few days (strong winds, mild temps). The likelihood of triggering a wind slab is decreasing but new snow will make it hard to identify slabs and it will take time for new snow to bond to the wind hammered surface.
Aspects: North, North East, East, South East, South.
Elevations: Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 1 - 2
