Weather Alert in Alaska
Winter Weather Advisory issued March 14 at 2:38PM AKDT until March 15 at 5:00AM AKDT by NWS Juneau AK
AREAS AFFECTED: Cape Fairweather to Lisianski Strait
DESCRIPTION: ...MODERATE TO HEAVY SNOWFALL RETURNS SUNDAY INTO MONDAY... .Bands of snow showers are currently pushing into the NE Gulf as of Saturday afternoon with widely varying conditions. Advisory level snowfall rates of around 1 inch per 3 hours is expected from Yakutat to Sitka, with lighter rates inland. If snow showers train over one location for an extended period of time, visibility could drop to a half mile at times with greater accumulations. This wave of showers is separate from a stronger low pressure system that is expected to track northward across the panhandle starting Sunday morning and continuing through Monday. Steady snowfall will return with heaviest rates across the northern and central Alaska Panhandle starting Sunday morning and continuing into Monday. Current forecast snowfall accumulations within the Winter Storm Warnings are between 6 to 14 inches, with locally higher amounts expected through Monday evening. For southern panhandle communities in Winter Weather Advisories, expecting snowfall accumulations of 3 to 6 inches, highest totals within interior Prince of Wales Island. The main forecast challenge for the southern panhandle will be the timing and transition period to a rain and snow mix, or potentially all rain by Sunday afternoon with temperatures reaching into the upper 30s to low 40s along the coast as the front pushes northward, limiting potential snowfall accumulations. Snow showers will then continue behind this system with widely variable accumulations through the rest of the week. * WHAT...For the Winter Weather Advisory, snow. Additional snow accumulations of 2 to 4 inches. For the Winter Storm Warning, heavy snow expected. Total snow accumulations of 10 to 13 inches.

Stratocumulus clouds are similar to altocumulus clouds in their
fluffy appearance, but have a slightly darker shade due to their additional mass.
A good way to distinguish the two cloud types is to hold your hand out and measure
the size of an individual cloud; if it is the size of your thumb it is generally
an altocumulus cloud, if it is the size of your hand it is generally a
stratocumulus cloud.
It is uncommon for stratocumulus clouds to produce precipitation, but if they do
it is usually a light rain or snow.

Next Topic: Altocumulus Clouds
A wall cloud forms underneath the base of a cumulonimbus cloud,
and can be a hotbed for deadly tornadoes.
Wall clouds are formed by air flowing into the cumulonimbus clouds, which can
result in the wall cloud descending from the base of the cumulonimbus cloud, or
rising fractus clouds which join to the base of the storm cloud as the wall cloud
takes shape.
Wall clouds can be very large, and in the Northern Hemisphere they generally
form at the southern edge of cumulonimbus clouds.
