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.

A hole punch cloud is an unusual occurrence when a disk-shaped
hole appears in a cirrostratus, cirrocumulus, or altocumulus cloud.
When part of the cloud forms ice crystals, water droplets in the surrounding area
of the cloud evaporate. The effect of this process produces a large elliptical
gap in the cloud. The hole punch cloud formation is rare, but it is not specific
to any geographic area.
Other names which have been used to describe this phenomena include fallstreak hole,
skypunch, and cloud hole.

A nimbostratus cloud is similar to a stratus cloud in its formless,
smooth appearance. However, a nimbostratus cloud is darker than a stratus cloud,
because it is thicker.
Unlike a stratus cloud, a nimbostratus cloud typically brings with it the threat
of moderate to heavy precipitation. In some cases, the precipitation may evaporate
before reaching the ground, a phenomenon known as virga.
