Weather Alert in California
Avalanche Warning issued February 24 at 5:44AM PST by NWS Reno NV
AREAS AFFECTED: Greater Lake Tahoe Area; Greater Lake Tahoe Area
DESCRIPTION: AVWREV The following message is transmitted at the request of the U.S. Forest Service Sierra Avalanche Center. BACKCOUNTRY AVALANCHE WARNING IMMEDIATE BROADCAST REQUESTED 05:30 PST Tue Feb 24 2026 The Sierra Avalanche Center in Truckee has issued a BACKCOUNTRY AVALANCHE WARNING for the following areas: NWS Reno NV - NVZ002 (Greater Lake Tahoe)...CAZ072 (Greater Lake Tahoe (CA)) * WHAT...HIGH avalanche danger exists in the backcountry. Large avalanches are expected across backcountry terrain. * WHERE...Central Sierra Nevada Mountains between Yuba Pass (Hwy 49) on the north and Ebbetts Pass (Hwy 4) on the south, including the greater Lake Tahoe area. This applies only to backcountry areas, not to ski areas and highways where avalanche mitigation programs exist. * WHEN...In effect from Tue 05:30 PST to Wed 07:00 PST. * IMPACTS...Significant rain on snow at all elevations will create widespread dangerous avalanche conditions in the mountains. Large avalanches capable of burying or injuring people are very likely in backcountry areas. Avalanches could travel farther downslope than usual and may run into areas traditionally thought of as safe. Natural avalanches are likely, and human-triggered avalanches are very likely. * PRECAUTIONARY / PREPAREDNESS ACTIONS...Very dangerous avalanche conditions exist in the backcountry. Traveling in, near, or below backcountry avalanche terrain is not recommended during HIGH avalanche danger. Consult https://www.sierraavalanchecenter.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.
