Avalanche Summary
Loose wet or moist snow is expected to continue to release naturally from steep terrain or rocky areas at lower elevations if temperatures rise and the sun comes out.
Snowpack Summary
Overnight freezing has consolidated previously loose wet snow at treeline and above. Recent moderate winds may have developed windslabs at upper elevations. Surface crusts are expected to break down during the day and then re-freeze overnight. Moist or wet snow below treeline is not expected to have much of a recovery and may continue to be isothermal and weak.
