AVAMSO The following message is transmitted at the request of Flathead Avalanche Center Hungry Horse MT. ...AVALANCHE WATCH ISSUED BY THE FLATHEAD AVALANCHE CENTER... 14:00 MST Mon Feb 16 2026 The Flathead Avalanche Center in Hungry Horse has issued a BACKCOUNTRY AVALANCHE WATCH for the following areas: NWS Missoula MT - MTZ002 (MTZ002) * WHAT...The avalanche danger is anticipated to increase to High (Level 4 of 5) Tuesday as an incoming storm brings heavy snow and strong winds to the forecast region. * WHERE...Mid and upper elevations in the Swan, Flathead, and Whitefish Ranges, and portions of Glacier National Park (the Apgar Range, the Lake McDonald Valley, and Marias Pass). * WHEN...In effect from Mon 14:00 MST to Tue 14:00 MST. * IMPACTS...A foot or more of new snow is forecasted at mid and upper- elevations. Moderate winds may drift snow into steep start zones. Many slopes and start zones harbor weak layers that are already sensitive to human triggers. The additional loading makes large to very large natural and triggered avalanches likely. Remotely-triggered avalanches will also be possible.</p> * PRECAUTIONARY / PREPAREDNESS ACTIONS...If the snowfall arrives as forecast, very dangerous avalanche conditions may develop. Travel in avalanche terrain is not recommended in these conditions. Avalanches may be triggered from below or from adjacent slopes. Avalanches may run long distances and can run into mature forests, valley floors, or flat terrain. Consult http://www.flatheadavalanche.org/ 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. |
