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 PDT Fri Mar 21 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 Friday 6 AM PST to Saturday
6 AM PST. Very dangerous avalanche conditions are likely to develop by
Saturday morning and raise the danger to High (Level 4of5).
* WHERE…The Selkirk, West and East Cabinet, and Bitterroot Mountains –
Silver Valley above 4,000 feet.
* WHEN…In effect from Fri 06:00 PDT to Sat 06:00 PDT.
* IMPACTS…A warm, wet storm will quickly deliver several feet of dense,
new snow and strong winds. The new snow load may be sufficient to overload a
variety of weak snow layers in the upper snowpack and cause a widespread
cycle of avalanches large enough to bury, injure, or kill a person. Some of
these avalanches could release naturally, and it will become 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
more detailed information.
Similar avalanche danger may exist at locations outside the coverage area of
this or any avalanche center.
