GNFAC Avalanche Forecast for Wed Jan 10, 2024

Not the Current Forecast


The Gallatin National Forest Avalanche Center is issuing a backcountry avalanche warning for the mountains around Cooke City, the Lionhead area near West Yellowstone, and the Centennial Mountains outside Island Park. The snowpack is weak and unstable and the recent snowfall and strong wind are creating very dangerous avalanche conditions. The danger is rated HIGH on all slopes. Human-triggered and natural avalanches are likely. Backcountry travelers should stay off of steep slopes and stay away from the bottom of steep slopes. Avalanches can be triggered from flat terrain. Steep slopes can avalanche far above and run into lower-angled terrain.

This warning will expire or be updated by 6:00 a.m. on Thursday, January 11, 2024.
