BULLETIN - IMMEDIATE BROADCAST REQUESTED
BACKCOUNTRY AVALANCHE WARNING
Idaho Panhandle Avalanche Center Sandpoint ID
Relayed by National Weather Service Missoula MT
844 AM MST Wed Dec 10 2025

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

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

...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.
