Weather Alert in Montana
Avalanche Warning issued February 23 at 7:09AM 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... 06:30 MST Mon Feb 23 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...Heavy snowfall rates and wind-drifted snow will create very dangerous avalanche conditions. * WHERE...Slopes above 5000 feet in the Whitefish, Swan and Flathead Ranges, and the Lake McDonald and Marias Pass areas of Glacier National Park.</p> * WHEN...In effect from Mon 06:30 MST to Tue 06:01 MST. * IMPACTS...Natural and human-triggered avalanches are very likely. Avalanches will release on weak layers buried 2 to 3+ feet deep. These will run long distances, travel into low-angle terrain, and can cover snowmobile trails. 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 the road 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.

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.

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.
