AVWOTX BACKCOUNTRY AVALANCHE WARNING 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. |

| Description: |
The following message is transmitted at the request of the Payette National Forest Avalanche Center. ...The Payette National Forest Avalanche Center in McCall Idaho has issued a BACKCOUNTRY AVALANCHE WATCH... * WHAT...An Avalanche Watch is in effect. Expect very dangerous avalanche conditions to develop over the next 24-48 hours. Heavy snowfall, wind, and rainfall will overload the current snowpack setup. * WHERE...The Salmon River Mountains, the West Mountains, and the surrounding mountain areas. * WHEN...In effect from Mon 12:00 MST to Tue 12:00 MST. * IMPACTS...Natural and human-triggered avalanches large enough to bury people are very likely to occur within 24-48 hours of this issuance. Avalanches may connect across terrain features like ridges or release multiple start zones at once. Additionally, rainfall to 7,000 feet will weaken surface snow and increase the likelihood of larger loose avalanches, as well as avalanches that break deeper within the snowpack. Smaller slopes, such as roadcuts, may also avalanche, depositing a surprising amount of debris on the road below. |
