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 PST Wed Dec 10 2025 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) * WHAT...An Avalanche Warning is in effect from Wednesday 7 AM to Thursday 7 AM. Very dangerous avalanche conditions will reemerge from another round of heavy rain and strong winds - this time climbing up to 8,000 feet. It will be very easy to trigger avalanches large enough to bury or kill you, and many will release spontaneously. Avoid travel in avalanche terrain during this period. * WHERE...The Selkirk Mountains, and West and East Cabinet Mountains above 4,000 feet. * WHEN...In effect from Wed 07:00 PST to Thu 07:00 PST. * IMPACTS...The next potent atmospheric river will deliver copious amounts of rain to an already stressed snowpack across the mountains of North Idaho and Northwestern Montana. The rain line will spike to around 8,000 feet on Wednesday and quickly overload buried weak snow layers. It will be very likely for backcountry travelers to trigger dangerous avalanches and natural avalanches are likely. Avalanches will break wide across terrain features and run long distances to lower elevation slopes. * PRECAUTIONARY / PREPAREDNESS ACTIONS...Travel in, near, 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. |

| Description: |
ESFMSO A prolonged atmospheric river is expected to bring periods of heavy rain for western Montana Monday night through Thursday. Rising snow levels will lead to a rain-on-snow event for elevations below 7,000 feet Monday night into Tuesday morning. Precipitation rates will briefly decrease Tuesday afternoon before a second surge of moisture arrives Tuesday night into Thursday. During the second surge, snow levels will be lower initially, ranging from 3,500 to 5,000 feet with some slushy snow accumulations across northwest Montana valleys, but will then rise to 6,000 to 8,000 feet Wednesday into Thursday. By Thursday, significant precipitation totals are forecast, with 1 to 4 inches in the valleys and 5 to 8 inches in the mountains, with locally higher totals over mountain crests. Landslides in areas of steep terrain and minor flooding in urban and poor-drainage areas are possible. Storm drains and ditches may become clogged with debris. You may want to preemptively shovel snow away from your homes. Watch basements for moisture intrusion. |
