By Moosetrack Megan

Posted: February 20, 2023

Flathead Range, Swan Range and Glacier National Park:

An Avalanche Warning is in effect. New snow and blowing snow are creating dangerous avalanche conditions. The avalanche danger will increase later in the day and will increase the higher you climb. Natural and human-triggered slides can be large enough to bury, injure, and kill someone. Avoid traveling on and beneath steep slopes.

Whitefish Range:

New snow and blowing snow are creating dangerous avalanche conditions. Safer options exist on slopes sheltered from the wind with lower slope angles. A triggered avalanche may become large enough to bury, injure, and kill someone.

The Gallatin National Forest Avalanche Center is issuing a Backcountry Avalanche Warning for the Bridger Range and the mountains around Cooke City. Heavy snowfall and strong winds in the last two days are creating very dangerous avalanche conditions. Natural and human-triggered avalanches are likely. Avalanche terrain and avalanche runout zones should be avoided. The avalanche danger is rated HIGH on all slopes. Contact the Gallatin National Forest Avalanche Center for more detailed information.

The avalanche danger has risen to high and will remain elevated throughout the day today and possibly tomorrow.

WHEN

In effect from Monday, February 20, 2023 – 7:19AM to Tuesday, February 21, 2023 – 7:00AM

WHERE

The southern Missions, southern Swans, and Rattlesnake Mountains.

IMPACTS

PRECAUTIONARY/PREPAREDNESS ACTIONS
