Weather Alert in Alaska
Special Weather Statement issued March 6 at 3:37AM 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 Friday will bring with it widespread rainfall of between 0.5 to 1.5 inches, although no flooding is expected. However ponding of water in low lying or poor drainage areas due to recent snow is likely. Active weather will then continue on Saturday as a compact 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.

A nimbostratus cloud is similar to a stratus cloud in its formless,
smooth appearance. However, a nimbostratus cloud is darker than a stratus cloud,
because it is thicker.
Unlike a stratus cloud, a nimbostratus cloud typically brings with it the threat
of moderate to heavy precipitation. In some cases, the precipitation may evaporate
before reaching the ground, a phenomenon known as virga.

Precipitation in the form of water droplets is called rain.
Rain generally has a tendency to fall with less intensity over a greater period
of time, and when rainfall is more severe it is usually less sustained.
Rain is the most common form of precipitation and happens with greater frequency
depending on the season and regional influences. Cities have been shown to have
an observable effect on rainfall, due to an effect called the urban heat island.
Compared to upwind, monthly rainfall between twenty and forty miles downwind of
cities is 30% greater.
