High Wind in Sern P.w. Snd, Alaska

Estimated wind gusts in the Copper River Delta based on wind in Thompson Pass and Valdez characterizing the magnitude of the gap wind.

The combination of high pressure in the interior and a low in the northern Gulf of Alaska created a tight pressure gradient over the North Gulf Coast of Alaska. The combined strong pressure gradient and cold air out flow from the interior along with a one and a half feet of new snow in the pass resulted in high winds over 100 mph re suspending the snow creating a blizzard in Thompson Pass.
