Weather Alert in Idaho
Avalanche Warning issued March 13 at 7:00AM PDT by NWS Spokane WA
AREAS AFFECTED: Shoshone, ID
DESCRIPTION: AVWOTX BACKCOUNTRY AVALANCHE WARNING IMMEDIATE BROADCAST REQUESTED 07:00 PDT Fri Mar 13 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 079 (Shoshone County) * WHAT...An Avalanche Warning is in effect from Friday 7 AM PST to Saturday 7 AM PST. Very dangerous avalanche conditions developed Wednesday night from heavy snowfall and strong to extreme winds, and these hazardous conditions are lasting through Saturday due to continued heavy snowfall in specific locations and sustained winds strong enough to transport the abundant new snow. A person's weight or a rider on a machine can very easily trigger avalanches large enough to bury or kill them, and some slides will release naturally. * WHERE...The Bitterroot Mountains - Silver Valley and the East Cabinet Mountains above 4,000 feet. * WHEN...In effect from Fri 07:00 PDT to Sat 07:00 PDT. * IMPACTS...An atmospheric river and violent jet stream joined forces to deliver heavy snowfall and strong to extreme winds to the Inland Northwest. Winds are subsiding considerably on Friday, however the sustained moderate to heavy snowfall is being measured in multiple feet at higher elevations. The recent snow has formed dangerous slabs of snow and will likely cause a widespread cycle of natural avalanches large enough to bury, injure, or kill a person. * PRECAUTIONARY / PREPAREDNESS ACTIONS...Very dangerous avalanche conditions exist in the mountains and widespread areas of unstable snow are expected. The largest slides may run long distances and can run into mature forests, valley floors, or flat terrain. Travel in or near avalanche terrain is not recommended and should be avoided during the period of significant instability.

Similar avalanche danger may exist at locations outside the coverage area of this or any avalanche center.

A mammatus cloud is a cloud with a unique feature which resembles
a web of pouches hanging along the base of the cloud.
In the United States, mammatus clouds tend to form in the warmer months, commonly
in the Midwest and eastern regions.
While they usually form at the bottom of a cumulonimbis cloud, they can also form
under altostratus, altocumulus, stratocumulus, and cirrus clouds. Mammatus clouds
warn that severe weather is close.

Next Topic: Rain
Precipitation can refer to many different forms of water that
may fall from clouds. Precipitation occurs after a cloud has become saturated to
the point where its water particles are more dense than the air below the cloud.
In most cases, precipitation will reach the ground, but it is not uncommon for
precipitation to evaporate before it reaches the earth's surface.
When precipitation evaporates before it contacts the ground it is called Virga.
Graupel, hail, sleet, rain, drizzle, and snow are forms of precipitation, but fog
and mist are not considered precipitation because the water vapor which
constitutes them isn't dense enough to fall to the ground.
