Friday's forecast calls for steady precipitation and rising freezing levels. This is a great recipe for avalanche activity.

Weather Forecast

Avalanche Summary
No new avalanches were reported on Thursday. New precipitation and wind on Wednesday night is expected to promote a new round of storm slab activity in high elevation lee terrain, and loose wet avalanche activity on steep, lower elevation slopes.
Snowpack Summary
As of Thursday morning, between 10 and 25cm of new snow had fallen. In areas where winds were strong, new wind slabs likely exist. At treeline and below, the new snow overlies either a crust or moist snow from Monday's rain event. In high alpine areas like Sky Pilot and the Chehalis Range the new snow overlies thick storm slabs which developed during the stormy weather at the end of January.A thick crust exists up to 180cm below the surface, although a strong bond is expected at this interface.
