Degrees of Avalanche Danger

Avalanche Activity

The highway avalanche hazard is MODERATE.

The avalanche hazard will remain elevated through Friday.


A fast storm has begun to push through. Expect heavy precipitation with moderate to strong winds Thursday night into Friday morning. Models suggest an inch plus of water and the freezing line around sea level. This should translate into a foot of snow. Natural avalanche activity may occur during the heat of the storm, though activity is unlikely to affect the highway. Precipitation looks to slow down Friday morning and taper through the day. Backcountry users should use extra caution through Friday while the snow pack adjusts.
