Avalanche Problems
Wind Slabs
Watch locally for thin wind slabs developing in the lees of ridges if we receive increased winds Sat as there is a lot of snow available for transport.
Aspects: North, North East, East, South East, South.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1 - 2
Persistent Slabs
The Nov 6 raincrust is down 50-90 cm. Although we have not seen any recent activity on this crust, this is still a significant layer in the snowpack. Evaluate this layer carefully prior to entering steeper/bigger terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 2 - 3
