Mar 17, 10:46 PM Mar 19, 10:00 AM
...HIT OR MISS SNOW SHOWERS CONTINUE THROUGH THE WEEK...

.The Winter Weather Advisories have been expanded in area and
extended in time through Thursday morning as scattered to
numerous bands snow showers are expected to continually push into
the panhandle through the late week. Another organized band is
likely to push through the area late Tuesday night through
Wednesday morning. Snowfall accumulations of 6 to 10 inches are
expected through Thursday, with some locally higher amounts
possible. However, accumulations will be limited during the
daytime due to warmer temperatures as are now into the latter half
of March. In addition, snowfall accumulations will be widely
variable across the advisory areas due to the hit or miss nature
of the showers, however rates as high as 1 inch per hour and
visibilities down to 1/2 mile or less will be possible within any
heavier showers that repeatedly move over the same location.
Advisories could be upgraded to short-fuse Winter Storm Warnings
if heavier snow showers continue over the same area.

WHAT: Snow. Additional snow accumulations of 6 to 10 inches,
with locally higher amounts possible. Visibilities reduced to
1/2 mile or less.

WHERE: Yakutat, Skagway, White Pass, Haines, Hoonah, Tenakee
Springs, Gustavus, Juneau, Sitka, Angoon, and Petersburg.

WHEN: Until 10 AM AKDT Thursday.

IMPACTS: Travel could be very difficult.

ADDITIONAL DETAILS: Another heavier band of snow will move
through late Tuesday night into Wednesday. Due to the showery
nature of the snow, accumulations will be highly variable with
periods of melting in sunny breaks. Snow showers are expected to
then continue through at least Thursday morning.
