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.

Snow is precipitation taking the form of ice crystals. Each ice crystal, or snowflake,
has unique characteristics, but all of them grow in a hexagonal structure.
Snowfall can last for sustained periods of time and result in significant buildup
of snow on the ground.
On the earth's surface, snow starts out light and powdery, but as it begins to melt
it tends to become more granular, producing small bits of ice which have the consistency of
sand. After several cycles of melting and freezing, snow can become very dense
and ice-like, commonly known as snow pack.

Stratus clouds are similar to altostratus clouds, but form at a
lower altitude and are identified by their fog-like appearance, lacking the
distinguishing features of most clouds.
Stratus clouds are wider than most clouds, and their base has a smooth, uniform
look which is lighter in color than a nimbostratus cloud.
The presence of a stratus cloud indicates the possibility of minor precipitation,
such as drizzle, but heavier precipitation does not typically arrive in the form
of a stratus cloud.
