Weather Alert in Alaska
Winter Weather Advisory issued March 1 at 2:45PM AKST until March 2 at 9:00AM AKST by NWS Juneau AK
AREAS AFFECTED: City and Borough of Sitka; Western Kupreanof and Kuiu Island
DESCRIPTION: ...MULTIPLE ROUNDS OF SNOWFALL EXPECTED THROUGH EARLY WEEK... The active weather pattern continues with split flow developing as an incoming front stalls across the central panhandle, with cold strong northerly outflow winds across the northern inner channels and warmer southerly winds across the southern panhandle. Portions of the central and southern panhandle will see moderate to heavy snowfall through Sunday evening as another surge of moisture pushes into the area. A transition to a rain snow mix is expected through Monday morning for the southern panhandle up to Sumner Strait. Main forecast challenge is potential for temperatures to warm up quicker than expected through Sunday night and into Monday morning with the front moving further north, limiting snowfall accumulations. Another system will bring more accumulating snow to the panhandle Monday night into Tuesday night. The track of this follow up feature could lead to significant swings in snow accumulations from Frederick Sound northward to the Icy Strait corridor. * WHAT...For the Winter Weather Advisory, snow. Additional snow accumulations of 4 to 6 inches. For the Winter Storm Watch, heavy snow possible. Total snow accumulations of 6 to 12 inches possible. Winds could gust as high as 35 mph. * WHERE...City and Borough of Sitka and Western Kupreanof Island and Kuiu Island. * WHEN...For the Winter Weather Advisory, until 9 AM AKST Monday. For the Winter Storm Watch, from late Monday night through late Tuesday night. * IMPACTS...Travel could be very difficult and is discouraged. The hazardous conditions could impact the morning or evening commute. * ADDITIONAL DETAILS...For the winter weather advisory, heaviest snowfall rates are expected through Sunday night. For the winter storm watch, the arctic boundary over the panhandle is expected to continue to linger around Frederick Sound Monday into Tuesday. An approaching system will bring a fresh influx of moisture and moderate to heavy snow, with a quicker transition to a rain snow mix for the outer coast depending upon the track of the low.

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.
