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.

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.
