A wind warning is in effect for Turnagain Arm and Anchorage Hillside until noon Wednesday, the National Weather Service said.
Beginning early Wednesday, sustained westerly winds of 40 to 60 mph, with gusts as high as 80 mph, are expected along Turnagain Arm and on the Hillside above 2,000 feet. At lower elevations around the Anchorage Bowl, sustained wind speeds up to 30 mph are expected through Wednesday, said Eric Drewitz, a meteorologist with weather service’s Anchorage office.
The winds are being driven into the area by a large low-pressure system from the Alaska Peninsula, Drewitz said.
