Avalanche Warning issued February 24 at 6:14AM MST by NWS Missoula MT

AREAS AFFECTED: Kootenai/Cabinet Region; West Glacier Region

DESCRIPTION: AVWMSO The following message is transmitted at the request of Flathead Avalanche Center Hungry Horse MT. ...AVALANCHE WARNING ISSUED BY THE FLATHEAD AVALANCHE CENTER... 06:00 MST Tue Feb 24 2026 The Flathead Avalanche Center in Hungry Horse has issued a BACKCOUNTRY AVALANCHE WARNING for the following areas: NWS Missoula MT - MTZ001 (MTZ001)...MTZ002 (MTZ002) * WHAT...New and wind-drifted snow have created very dangerous avalanche conditions. * WHERE...Slopes above 5000 feet in the Flathead Range and the Lake McDonald and Marias Pass areas of Glacier National Park. Slopes above 6500 feet in the Swan and Whitefish Ranges. * WHEN...In effect from Tue 06:00 MST to Wed 06:00 MST. * IMPACTS...Natural and human-triggered avalanches are very likely. Avalanches will release on weak layers buried two to four feet deep. These will run long distances, travel into low-angle terrain, and can cover snowmobile and snowshoeing trails and backcountry ski routes. Avalanches may connect across terrain features like ridges, releasing multiple start zones at once. Avalanches can be triggered from long distances away. Smaller slopes, such as roadcuts, may also avalanche, depositing a surprising amount of debris on roads below. * PRECAUTIONARY / PREPAREDNESS ACTIONS...Very dangerous avalanche conditions. Pay close attention to the terrain around you. Avoid traveling on and under steep slopes. Consult http://www.flatheadavalanche.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.

Hole Punch Clouds Next Topic: Mammatus Clouds

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.

Nimbostratus Clouds Next Topic: Precipitation

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.
