AVWMSO The following message is transmitted at the request of Idaho Panhandle Avalanche Center Sandpoint ID. ...AVALANCHE WARNING ISSUED BY THE IDAHO PANHANDLE AVALANCHE CENTER... 16:00 PST Mon Feb 23 2026 The Idaho Panhandle Avalanche Center in Sandpoint has issued a BACKCOUNTRY AVALANCHE WARNING for the following areas: NWS Missoula MT - MTZ001 (MTZ001) NWS Spokane WA - ID 017 (Bonner County)...ID 021 (Boundary County)...ID 079 (Shoshone County) * WHAT...An Avalanche Warning is in effect from Monday 4 PM to Tuesday 4 PM. Very dangerous avalanche conditions have developed from heavy snowfall and strong winds, and will last through Tuesday. You can very easily trigger avalanches large enough to bury or kill you, and some will release spontaneously. Avoid travel in avalanche terrain during this period. * WHERE...The Selkirk Mountains, West and East Cabinet Mountains, Purcell Mountains, and the Bitterroot Mountains - Silver Valley above 4,000 feet. * WHEN...In effect from Mon 16:00 PST to Tue 16:00 PST. * IMPACTS...Dense snowfall and widespread drifting has formed dangerous slabs of snow over multiple fragile weak snow layers. The new snow is adding enough stress to the snowpack to cause a widespread cycle of avalanches large enough to bury, injure, or kill a person. Some of these avalanches could propagate widely across terrain features like ridges, and run long distances into mature forests, valley floors, or flat terrain. It will be very easy for backcountry travelers to trigger them. * PRECAUTIONARY / PREPAREDNESS ACTIONS...Travel in and around avalanche terrain is not recommended during this period. Consult http://www.idahopanhandleavalanche.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. |

AVWMSO The following message is transmitted at the request of Flathead Avalanche Center Hungry Horse MT. ...AVALANCHE WARNING ISSUED BY THE FLATHEAD AVALANCHE CENTER... 06:30 MST Mon Feb 23 2026 The Flathead Avalanche Center in Hungry Horse has issued a BACKCOUNTRY AVALANCHE WARNING for the following areas: NWS Missoula MT - MTZ001 (MTZ001)...MTZ002 (MTZ002) * WHAT...Heavy snowfall rates and wind-drifted snow will create very dangerous avalanche conditions. * WHERE...Slopes above 5000 feet in the Whitefish, Swan and Flathead Ranges, and the Lake McDonald and Marias Pass areas of Glacier National Park.</p> * WHEN...In effect from Mon 06:30 MST to Tue 06:01 MST. * IMPACTS...Natural and human-triggered avalanches are very likely. Avalanches will release on weak layers buried 2 to 3+ feet deep. These will run long distances, travel into low-angle terrain, and can cover snowmobile trails. Avalanches may connect across terrain features like ridges, releasing multiple start zones at once. Avalanches can be triggered from long distances away. Smaller slopes, such as roadcuts, may also avalanche, depositing a surprising amount of debris on the road below. * PRECAUTIONARY / PREPAREDNESS ACTIONS...Very dangerous avalanche conditions. Pay close attention to the terrain around you. Avoid traveling on and under steep slopes. 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. |
