Weather Alert in Alaska
Special Weather Statement issued September 5 at 2:00PM AKDT by NWS Anchorage AK
AREAS AFFECTED: Kuskokwim Delta Coast and Nunivak Island
DESCRIPTION: A front from a strong low pressure system in the Bering Sea is impacting the Kuskokwim Delta Coast. Southeast winds continue to increase in strength this afternoon and become strong and gusty by tonight. Winds gusts of up to 50 mph at times are likely in communities along the northern Kuskokwim Bay Coast tonight through Saturday morning before slowly diminishing through Saturday afternoon into Sunday morning. Locations impacted include Kongiganak, Kwigillingok, and Kipnuk. Along with the strong push of southeasterly winds, water levels will also increase with peak water levels occurring late Saturday morning. Water levels are expected to peak at 1 to 2 feet above the normal highest tide line. While significant coastal flooding is not expected, low-lying areas could fill up with water, especially around Kipnuk and Kwigillingok. Higher wave heights are also likely in the coastal waters of the Kuskokwim Delta and near the coast with 5 to 8 foot waves likely. Wave heights will peak Saturday morning and slowly subside through Sunday morning. Higher waves breaking along the coast could cause some localized areas of beach erosion.

and are composed mainly of ice crystals.
They are thin and wispy in appearance.
What do they indicate?

A contrail is an artificial cloud, created by the passing of an
aircraft.
Contrails form because water vapor in the exhaust of aircraft engines is suspended
in the air under certain temperatures and humidity conditions. These contrails
are called exhaust contrails.
Another type of contrail can form due to a temporary reduction in air pressure
moving over the plane's surface, causing condensation.
These are called aerodynamic contrails.
When you can see your breath on a cold day, it is also because of condensation.
The reason contrails last longer than the condensation from your breath is
because the water in contrails freezes into ice particles.
