Weather Alert in Idaho
Avalanche Warning issued February 23 at 5:54PM PST by NWS Spokane WA
AREAS AFFECTED: Bonner, ID; Boundary, ID; Shoshone, ID
DESCRIPTION: AVWOTX BACKCOUNTRY AVALANCHE WARNING 16:00 PST Mon Feb 23 2026 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 have developed from heavy snowfall and strong winds, and will last through Tuesday. 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, Purcell Mountains, and the Bitterroot Mountains - Silver Valley above 4,000 feet. * WHEN...In effect from Mon 16:00 PST to Tue 16:00 PST. * IMPACTS...Dense snowfall and widespread drifting has formed dangerous slabs of snow over multiple fragile weak snow layers. The new snow is adding enough stress to the snowpack to cause a widespread cycle of avalanches large enough to bury, injure, or kill a person. Some of these avalanches could propagate widely across terrain features like ridges, and run long distances into mature forests, valley floors, or flat terrain. It will be very easy for backcountry travelers to trigger them. * PRECAUTIONARY / PREPAREDNESS ACTIONS...Travel in and around 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.

Stratus clouds are similar to altostratus clouds, but form at a
lower altitude and are identified by their fog-like appearance, lacking the
distinguishing features of most clouds.
Stratus clouds are wider than most clouds, and their base has a smooth, uniform
look which is lighter in color than a nimbostratus cloud.
The presence of a stratus cloud indicates the possibility of minor precipitation,
such as drizzle, but heavier precipitation does not typically arrive in the form
of a stratus cloud.

Next Topic: Altostratus Clouds
Similar to cirrocumulus clouds, altocumulus clouds are
characterized by cloud patches. They are distinguished by larger cloudlets
than cirrocumulus clouds but are still smaller than stratocumulus clouds.
Altocumulus clouds most commonly form in middle altitudes (between 2 and 5 km)
and may resemble, at times, the shape of a flying saucer.
These uncommon formations, called altocumulus lenticularis, are created by uplift
in the atmosphere and are most often seen in close proximity to mountains.
