AVAMSO The following message is transmitted at the request of Idaho Panhandle Avalanche Center Sandpoint ID. ...AVALANCHE WATCH ISSUED BY THE IDAHO PANHANDLE AVALANCHE CENTER... 19:00 PST Sun Feb 22 2026 The Idaho Panhandle Avalanche Center in Sandpoint has issued a BACKCOUNTRY AVALANCHE WATCH 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 Watch is in effect from Sunday 7 PM PST to Monday 4 PM PST. Very dangerous avalanche conditions are likely to develop by Monday afternoon and raise the danger to High (Level 4of5). * WHERE...The Selkirk, West and East Cabinet, Purcell, and Bitterroot Mountains - Silver Valley above 4,000 feet. * WHEN...In effect from Sun 19:00 PST to Mon 16:00 PST. * IMPACTS...A warm, wet storm will deliver moderate to heavy snowfall to the snowpack. The new snowfall may add enough weight to the snowpack to overload fragile weak snow layers and cause a widespread cycle of avalanches large enough to bury, injure, or kill a person. Some of these avalanches could release naturally, propagate widely across terrain features like ridges, and run long distances into mature forests, valley floors, or flat terrain. It will become very easy for backcountry travelers to trigger them. * PRECAUTIONARY / PREPAREDNESS ACTIONS...Travel in or below 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.
