Weather Alert in Alaska
Winter Storm Watch issued February 26 at 4:06PM AKST until March 1 at 6:00AM AKST by NWS Juneau AK
AREAS AFFECTED: City and Borough of Juneau; Petersburg Borough
DESCRIPTION: ...POTENTIAL OVERRUNNING SNOW EVENT FOR SUNDAY INTO MONDAY... .Cold Arctic air is expected to move into the panhandle for the end of the week into next week. With the cold air in place, moisture associated with a low over the Gulf into the Bering Sea is expected to move over the area. With the warmer nature of the moisture and colder air at the surface, snow is expected to fall across the Panhandle. Current guidance suggests that the most significant snow will be over the parts of the Central Panhandle that holds onto the cold air longer. There is the potential that this overrunning snow event lasts into the middle to end of next week. This will depend on how long the cold air persists through the Inner Channels. Meanwhile snow showers continue into the Thursday night for parts of the panhandle. * WHAT...Heavy snow possible. Total snow accumulations of 6 to 12 inches possible for Juneau. Total snow accumulations of 6 to 16 inches possible for Petersburg. * WHERE...City and Borough of Juneau and Petersburg Borough. * WHEN...From Saturday morning through late Saturday night. * IMPACTS...Travel could be very difficult. The hazardous conditions could impact the morning or evening commute. * ADDITIONAL DETAILS...Snow is expected to start Saturday morning and could potentially last into the start of next week with cold Arctic air in place and warm, moisture rich air moving over.

Cirrocumulus clouds form at high altitudes (usually around 5 km)
and have distinguishing characteristics displayed in a fine layer of
small cloud patches. These small cloud patches are sometimes referred to as
"cloudlets" in relation to the whole cloud formation.
Cirrocumulus clouds are formed from ice crystals and water droplets. Often, the
water droplets in the cloud freeze into ice crystals and the cloud becomes a
cirrostratus cloud. Because of this common occurrence, cirrocumulus cloud
formations generally pass rapidly.
