Weather Alert in Alaska
High Wind Warning issued February 24 at 5:31AM AKST until February 26 at 9:00AM AKST by NWS Anchorage AK
AREAS AFFECTED: Thompson Pass
DESCRIPTION: * WHAT...North winds 40 to 65 mph with gusts up to 85 mph expected. Wind chills dropping to 40 below Wednesday night. * WHERE...Thompson Pass. * WHEN...From 3 AM Wednesday to 9 AM AKST Thursday. * IMPACTS...High winds may move loose debris, damage property, and cause power outages. Travel will be difficult. Blowing snow due to high winds will reduce visibilities to one half mile or less at times. The dangerously cold wind chills as low as 40 below zero could cause frostbite on exposed skin in as little as 10 minutes. * ADDITIONAL DETAILS...North to northeast winds will rapidly strengthen late Tuesday afternoon through Tuesday night, then peak Wednesday through Wednesday night. As winds first develop, freshly fallen snow will easily blow around, leading to near-blizzard conditions at times. As snow becomes scoured out, visibilities should improve. Winds will very slowly diminish Thursday through Friday.
INSTRUCTION: People are urged to secure loose objects that could be blown around or damaged by the wind. Prepare for the possibility of widespread power outages. Use caution if you must drive.

Similar to cirrocumulus clouds, altocumulus clouds are
characterized by cloud patches. They are distinguished by larger cloudlets
than cirrocumulus clouds but are still smaller than stratocumulus clouds.
Altocumulus clouds most commonly form in middle altitudes (between 2 and 5 km)
and may resemble, at times, the shape of a flying saucer.
These uncommon formations, called altocumulus lenticularis, are created by uplift
in the atmosphere and are most often seen in close proximity to mountains.

Cirrocumulus clouds form at high altitudes (usually around 5 km)
and have distinguishing characteristics displayed in a fine layer of
small cloud patches. These small cloud patches are sometimes referred to as
"cloudlets" in relation to the whole cloud formation.
Cirrocumulus clouds are formed from ice crystals and water droplets. Often, the
water droplets in the cloud freeze into ice crystals and the cloud becomes a
cirrostratus cloud. Because of this common occurrence, cirrocumulus cloud
formations generally pass rapidly.
