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... 07:00 PDT Sat Mar 14 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 079 (Shoshone County) * WHAT...An Avalanche Warning is in effect from Saturday 7 AM PST to Sunday 7 AM PST. Very dangerous avalanche conditions developed Wednesday night from heavy snowfall and strong to extreme winds, and these hazardous conditions are lasting through Sunday due to continued heavy snowfall in specific locations and sustained winds strong enough to transport the abundant new snow. A person's weight or a rider on a machine can very easily trigger avalanches large enough to bury or kill them, and some slides will release naturally. * WHERE...The Bitterroot Mountains - Silver Valley and the East Cabinet Mountains above 4,000 feet. * WHEN...In effect from Sat 07:00 PDT to Sun 07:00 PDT. * IMPACTS...An atmospheric river and violent jet stream joined forces to deliver heavy snowfall and strong to extreme winds to the Inland Northwest. Wind speeds peaked on Wednesday night and have subsided considerably since then, however an uptick is expected on Saturday with gusts reaching 40 to 50 mph possible. The sustained moderate to heavy snowfall is being measured in multiple feet at higher elevations and winds are forecasted to remain strong enough to cause significant transport and redistribution of snow. The recent snowfall has formed dangerous slabs of snow and will likely cause a widespread cycle of natural avalanches large enough to bury, injure, or kill a person. * PRECAUTIONARY / PREPAREDNESS ACTIONS...Very dangerous avalanche conditions exist in the mountains and widespread areas of unstable snow are expected. The largest slides may run long distances and can run into mature forests, valley floors, or flat terrain. Travel in or near avalanche terrain is not recommended and should be avoided during this period of significant instability. 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.
