Avalanche Warning issued February 25 at 8:24AM MST by NWS Missoula MT
AREAS AFFECTED: Potomac/Seeley Lake Region
DESCRIPTION: AVWMSO The following message is transmitted at the request of West Central Montana Avalanche Center Missoula MT. ...AVALANCHE WARNING ISSUED BY THE WEST CENTRAL MONTANA AVALANCHE CENTER... 07:30 MST Wed Feb 25 2026 The West Central Montana Avalanche Center in Missoula has issued a BACKCOUNTRY AVALANCHE WARNING for the following areas: NWS Missoula MT - MTZ043 (MTZ043) * WHAT...Several feet of new snow, coupled with strong ridgetop winds, have created dangerous avalanche conditions. This new snow will likely overload buried weak layers and lead to large natural avalanches. Travel in and below avalanche terrain is not recommended. * WHERE...The Seeley Lake mountains above 5500'. * WHEN...In effect from Wed 07:30 MST to Thu 04:00 MST. * IMPACTS...Natural and human-triggered avalanches are likely. Avalanches will release on weak layers buried two to four feet deep. It will be possible to remotely trigger avalanches from below, above, or to the side of steeper slopes. Avalanches may connect across terrain features, creating large and destructive avalanches. * PRECAUTIONARY / PREPAREDNESS ACTIONS...Dangerous avalanche conditions exist. Travel in avalanche terrain is not recommended. Avoid travel underneath steep slopes. Even small slopes like roadcuts and gullies have potential to deposit enough debris to bury or injure a person. Consult https://missoulaavalanche.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.

A fractus cloud (scud) is a fragmented, tattered cloud which has
likely been sheared off of another cloud. They are accessory clouds, meaning they
develop from parent clouds, and are named in a way which describes the original
cloud which contained them.
Fractus clouds which have originated from cumulus clouds are referred to as
cumulus fractus, while fractus clouds which have originated from stratus clouds
are referred to as stratus fractus. Under certain conditions a fractus cloud might
merge with another cloud, or develop into a cumulus cloud, but usually a
fractus cloud seen by itself will dissipate rapidly.
They are often observed on the leading and trailing edges of storm clouds,
and are a display of wind activity.

Weather Topic: What is Graupel?
Home - Education - Precipitation - Graupel
Next Topic: Hail
Graupel is a form of precipitation that is created by atmospheric conditions
which cause supercooled water droplets to contact snow crystals and freeze to
their surface.
Sometimes known as soft hail or snow pellets, graupel is delicate and easily
destroyed by touch. Whereas hail usually falls during severe weather, graupel
doesn't require such conditions to form, and can form in mild precipitation
similar to situations which produce snowfall.
