Alert

High Wind Warning until 06:00PM Sunday

* WHAT...Northeast winds 30 to 50 mph with gusts up to 75 mph expected.

* WHERE...Thompson Pass.

* WHEN...Until 6 PM AKST this evening.

* IMPACTS...High winds may move loose debris, damage property, and cause power outages. Travel will be difficult, especially for high profile vehicles. The combination of very cold temperatures and strong winds will drive wind chills down to 40 below zero today and even further to near 50 below zero tonight into Monday. Strong winds could transport snow and abruptly reduce visibility.

* ADDITIONAL DETAILS...Winds will continue to steadily increase this morning. While warning level gusts are not expected for the town of Valdez at this time, gusts to 55 mph will be possible. No new snowfall is expected with this system, but any transportable snow could easily be blown around. Be prepared for sudden reductions to visibility less than one half mile through the pass.

* AFFECTED AREAS: NORTHEAST PRINCE WILLIAM SOUND

Instructions:

Wind chills of 40 below zero will cause frostbite on exposed skin in as little as 10 minutes. 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.
