Avalanche Warning
Idaho Panhandle Avalanche Center Sandpoint ID
Relayed by National Weather Service Spokane WA
504 PM PST Mon Dec 8 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)...
ID 079 (Shoshone County)
* WHAT...An Avalanche Warning is in effect from Monday 4 PM to
Tuesday 4 PM. Very dangerous avalanche conditions will develop
overnight and last though Tuesday as heavy, wet snowfall
transitions to heavy rain along with strong winds. 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, and
the Silver Valley-Bitterroot Mountains above 4,000 feet.
* WHEN...In effect from Mon 16:00 PST to Tue 16:00 PST.
* IMPACTS...A potent atmospheric river characterized by near-
historic moisture will introduce a firehose of moisture into
North Idaho and Northwestern Montana. The rain line will rise to
around 7,000 to 7,500 feet overnight Monday and will saturate
recent snowfall and overload pre-existing weak snow layers. It
will be very likely for backcountry travelers to trigger
avalanches and natural avalanches are likely. Avalanches can
break wide across terrain features and run long distances to
lower elevations.
* PRECAUTIONARY / PREPAREDNESS ACTIONS...Travel in 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.

break wide across terrain features and run long distances to lower
elevations.
* PRECAUTIONARY / PREPAREDNESS ACTIONS...Travel in avalanche terrain is not
recommended during this period.
Consult http://www.idahopanhandleavalanche.org/ or www.avalanche.org for

BULLETIN - IMMEDIATE BROADCAST REQUESTED
Backcountry Avalanche Watch
Idaho Panhandle Avalanche Center Sandpoint ID
Relayed by National Weather Service Missoula MT
713 AM MST Mon Dec 8 2025
The following message is transmitted at the request of Idaho Panhandle
Avalanche Center Sandpoint ID.
...AVALANCHE WATCH ISSUED BY THE IDAHO PANHANDLE AVALANCHE CENTER...
06:00 PST Mon Dec 08 2025
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 Monday 6 AM PST to Monday 4 PM
PST. Very dangerous avalanche conditions could develop overnight Monday
and raise the danger to High (Level 4 of 5).
* WHERE...The Selkirk, West and East Cabinet Mountains, and Bitterroot
Mountains - Silver Valley.
* WHEN...In effect from Mon 06:00 PST to Mon 16:00 PST.
* IMPACTS...Heavy, wet snowfall Monday will transition to heavy rain
overnight. A potent atmospheric river characterized by near-historic
moisture will introduce a firehose of moisture into North Idaho and
Northwestern Montana. The rain line will rise to around 7,000 feet
overnight Monday and will saturate recent snowfall and buried weak layers,
and could provoke a widespread cycle of avalanches large enough to bury,
injure, or kill a person. Some of these avalanches could release naturally,
and it will be 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

...NEAR RECORD HEAVY PRECIPITATION TO BRING SMALL STREAM RISES, RISK
FOR ROCK AND LANDSLIDES, AND MINOR FLOODING THIS WEEK...
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.
