Snowpack Summary
After Monday's new snow, another 20 cm is expected to accumulate by the end of the day Tuesday. Moderate winds will redistribute falling snow and begin developing cohesive slabs that may not bond well to the wind-affected surface snow it's falling on. The new snow covers a variety of wind affected surfaces from scoured and wind-pressed to stiff wind slabs as a result of the recent extreme wind event. Widespread wind slabs developed in the alpine with pockets of soft snow in sheltered areas and lower elevations. This layer of wind-affected snow sits above a crust, old wind-pressed snow surfaces, or surface hoar in the most sheltered areas. The mid-pack is well-settled and strong.
