Avalanche Summary

On Wednesday, wind slabs in lee features were reactive to explosives.On Tuesday, wind and storm slabs up to size 1 were reactive to skier traffic on sun affected slopes in the alpine.

Snowpack Summary

Up to 15 cm new snow covers a melt-freeze crust on most aspects except for north facing slopes above 2000 m, where new snow overlies dry, settled snow. At these sheltered upper elevations, the recent 10-35 cm snow over the past week is bonding well to the underlying layers.Below treeline snow is disappearing rapidly.
