Weather Alert in Alaska
High Wind Watch issued February 23 at 3:34PM AKST until February 25 at 9:00PM AKST by NWS Anchorage AK
AREAS AFFECTED: Kodiak Island Northeast
DESCRIPTION: * WHAT...Northwest winds 35 to 50 mph with gusts up to 75 mph possible. Wind chills dropping as low as 15 below zero Wednesday morning. * WHERE...Northeast end of Kodiak Island, including Kodiak City. * WHEN...From late Tuesday night through Wednesday evening. * IMPACTS...High winds could move loose debris, damage property, and cause power outages. Travel could be difficult. Wind chills as low as 15 below zero could result in hypothermia or frostbite if precautions are not taken. * ADDITIONAL DETAILS...The pattern is very similar to last Thursday night when Kodiak City observed high winds, with cold Arctic air surging across Kodiak Island Tuesday night through Wednesday. There is a subtle difference in the upper levels, with a disturbance possible passing just north of the island instead of passing overhead. Thus, winds in this upcoming event could be just a bit weaker than last Thursday night. The strongest winds are expected Wednesday morning.
INSTRUCTION: A high wind watch means there is potential for a hazardous high wind event. Monitor the latest forecasts and warnings for updates on this situation. Fasten loose objects or shelter objects in a safe location prior to the onset of winds.

A fractus cloud (scud) is a fragmented, tattered cloud which has
likely been sheared off of another cloud. They are accessory clouds, meaning they
develop from parent clouds, and are named in a way which describes the original
cloud which contained them.
Fractus clouds which have originated from cumulus clouds are referred to as
cumulus fractus, while fractus clouds which have originated from stratus clouds
are referred to as stratus fractus. Under certain conditions a fractus cloud might
merge with another cloud, or develop into a cumulus cloud, but usually a
fractus cloud seen by itself will dissipate rapidly.
They are often observed on the leading and trailing edges of storm clouds,
and are a display of wind activity.

Weather Topic: What is Graupel?
Home - Education - Precipitation - Graupel
Next Topic: Hail
Graupel is a form of precipitation that is created by atmospheric conditions
which cause supercooled water droplets to contact snow crystals and freeze to
their surface.
Sometimes known as soft hail or snow pellets, graupel is delicate and easily
destroyed by touch. Whereas hail usually falls during severe weather, graupel
doesn't require such conditions to form, and can form in mild precipitation
similar to situations which produce snowfall.
