Deep Persistent Slabs
The weak Oct.26 facets and depth hoar at the base of the snowpack have a significant slab (50-130cm thick) sitting above them. The likelihood of triggering this layer has decreased, but if it does get triggered, the avalanche will be large in size.
Be aware of the potential for full depth avalanches due to weak layers at the base of the snowpack.Avoid thin, rocky or unsupported slopes.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Expected Size1.5 - 3
Thin wind slabs are stubborn but still show potential for triggering in the alpine. Increased winds on Thursday may add to their development. These will not be a long term problem.
If triggered the wind slabs may step down to deeper layers resulting in large avalanches.
Aspects: North, North East, East.
