AREAS AFFECTED: Glacier Bay; Eastern Chichagof Island; Cape Fairweather to Lisianski Strait; Admiralty Island; City and Borough of Juneau
DESCRIPTION: ...MULTIPLE ROUNDS OF SNOWFALL EXPECTED THROUGH EARLY WEEK... Snow continues for the central inner channels from Wrangell and Kake northward though rates are starting to diminish. Expect the snow to continue to diminish through the day as the system moves off to the east. 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...Heavy snow possible. Total snow accumulations of 6 to 11 inches possible. Winds could gust as high as 45 mph. * WHERE...Glacier Bay, Eastern Chichagof Island, Cape Fairweather to Lisianski Strait, Admiralty Island and City and Borough of Juneau. * WHEN...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...An 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 to the central panhandle. A more southerly track of this feature could lead to much lower snow totals for communities north of Angoon.

Similar to cirrocumulus clouds, altocumulus clouds are
characterized by cloud patches. They are distinguished by larger cloudlets
than cirrocumulus clouds but are still smaller than stratocumulus clouds.
Altocumulus clouds most commonly form in middle altitudes (between 2 and 5 km)
and may resemble, at times, the shape of a flying saucer.
These uncommon formations, called altocumulus lenticularis, are created by uplift
in the atmosphere and are most often seen in close proximity to mountains.

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.
