Avalanche Warning issued December 22 at 5:07AM MST by NWS Pocatello ID
Non-Weather Emergency Message. Not sent to IPAWS.
Effective: Mon December 22, 2025, 5:07 AM
Expires: Tue December 23, 2025, 5:30 AM
AVWPIH * WHAT...Avalanche Warning. The avalanche danger is HIGH on all slopes. Natural and human triggered slides are very likely. * WHERE...The mountains near Island Park, West Yellowstone, and Cooke City. * WHEN...Until 530 AM Tuesday. * IMPACTS...Heavy snowfall on a snowpack with unstable weak layers will make human triggered avalanches very likely.
Very dangerous avalanche conditions exist. Backcountry travelers should stay off steep slopes and 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. Consult www.mtavalanche.com or www.avalanche.org for more detailed information. Similar avalanche danger may exist at locations outside the coverage area of this or any avalanche center.

The times presented here are based upon the solunar theory, which is the idea that the movements of
fish and other animals are affected by the location of the sun and moon. The major periods are
believed to be the times of the greatest animal activity and occur when the moon is directly
overhead or underfoot (lunar transits). The minor periods also see increased activity and
occur when the moon is rising or setting. The strongest activity occurs during full or new moons,
and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
