Degrees of Avalanche Danger

Avalanche Activity

The highway avalanche hazard is MODERATE.

The avalanche hazard should decrease through Thursday.


A large storm brought heavy precipitation Sunday evening through Monday. Initially, snow fell to sea level. The freezing line rose to around 500 feet Monday night. 2-3 inches of water translated into a couple feet of new snow above 500 feet. Moderate to strong wind loaded western aspects. Avalanche observations have been obscured.

Expect some very light precipitation to linger through Tuesday night with temperatures decreasing and light wind becoming north. Conditions look to remain dry Wednesday and Thursday with north wind increasing. The avalanche hazard should slowly decrease as time allows the snowpack to adjust and stabilize. Natural avalanches are possible and human triggered avalanches are still probable Tuesday. Backcountry users should choose terrain wisely.
