Weather Alert in Alaska
Special Weather Statement issued March 5 at 2:57PM AKST by NWS Juneau AK
AREAS AFFECTED: Municipality of Skagway; Haines Borough and Klukwan; Glacier Bay; Eastern Chichagof Island; Cape Fairweather to Lisianski Strait; City and Borough of Sitka; Admiralty Island; City and Borough of Juneau; Petersburg Borough; Western Kupreanof and Kuiu Island; Prince of Wales Island; City and Borough of Wrangell; Ketchikan Gateway Borough; City of Hyder; Annette Island
DESCRIPTION: After the waves of snow which have been moving through SE AK the past few weeks, warming temperatures are bringing a changeover to rain for the area. Snow levels will reach between 2k to 4k feet on Friday across the Icy Strait Corridor, and climb above 7k feet for the southern panhandle. A gale force front moving through the area on Friday will bring with it widespread rainfall of between 0.5 to 1.5 inches, although no flooding is expected. Active weather will then continue on Saturday as a low pressure system starts to make its way into the northern gulf. This low will bring southwesterly strong gale force winds into the southern gulf, eventually pushing into the central and southern panhandle. This will bring windy conditions inland as well, with the strongest winds along the gulf coast. A cool down occurs over the weekend, with another wave of moisture racing across the Gulf and into the panhandle on Saturday. By Saturday night, snow showers will be in abundance throughout the region, and will continue into early next week, resulting in variable snow accumulations.

Next Topic: Cirrocumulus Clouds
Altostratus clouds form at mid to high-level altitudes
(between 2 and 7 km) and are created by a warm, stable air mass which causes
water vapor
to condense as it rise through the atmosphere. Usually altostratus clouds are
featureless sheets characterized by a uniform color.
In some cases, wind punching through the cloud formation may give it a waved
appearance, called altostratus undulatus. Altostratus clouds
are commonly seen with other cloud formations accompanying them.

Next Topic: Cirrus Clouds
Cirrostratus clouds are high, thin clouds that form above
20,000 feet and are made mostly of ice crystals. They sometimes look like giant
feathers, horse tails, or curls of hair in the sky.
These clouds are pushed by the jet stream and can move at high speeds reaching
100 mph.
What do they indicate?
They indicate that a precipitation is likely within 24 hours.
