Relayed by National Weather Service Spokane WA
619 AM PST Mon Dec 8 2025
The following message is transmitted at the request of 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
4of5).
* 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

Similar avalanche danger may exist at locations outside the

...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.

...RIVER RISES AND INCREASED RISK FOR MUD AND ROCK SLIDES THIS
WEEK...
A series of warm, wet, and breezy weather will bring periods of high
mountain snow and heavy rain to low to middle elevation areas of the
central and southern Idaho Panhandle mountains Monday through
Wednesday. Snow levels will fluctuate between 5000 and 7000 feet.
Lower elevation snowmelt in addition to the rain will lead to rises
on
small creeks and streams. This will also bring an increased risk for
mud and rock slides in areas of steep and susceptible terrain.
