Snowpack Summary
Previous Strong winds from W and N directions have left wind slabs and wind effect in open areas. The upper snowpack has settled to form a cohesive stiff slab that is sitting on three persistent weak layers mid-pack (down 50 to 80cm) which can be found throughout the forecast region, and have produced many large avalanches that have run full path.
Avalanche Summary
Minimal evidence of recent activity exists: mainly small windslabs in the S and W facing alpine. Widespread wind effect is evident. An extensive cycle was seen as the persistent slab became overloaded with successive storms. Avalanches to sz 3.5 were observed from most aspects and most elevations with the majority of the action seen around 21-2500m
