Strong winds are forecast to develop overnight in Anchorage, with potential for gusts up to 80 miles per hour in higher elevations and along Turnagain Arm on Tuesday, the National Weather Service said in a high wind warning.
Southeast winds of 50 to 65 miles per hour, gusting up to 80 miles per hour, are expected in Anchorage's Upper Hillside neighborhood and along Turnagain Arm on Tuesday, the warning said.
In lower elevations, winds of 20 to 30 miles per hour and gusts up to 45 miles per hour are expected to develop, the agency said.
The warning includes Anchorage, Eagle River, Eklutna and Indian, and is in effect from 6 a.m. to 7 p.m. Tuesday.
Winds are expected to pick up overnight, and then peak by midday Tuesday, the warning said. By early Tuesday evening wind is forecast to diminish below warning levels, but gusts are expected to continue through the night.
An area of low pressure over the Bering Sea and Bristol Bay is driving the winds, which is not unusual, said meteorologist Kaitlyn O'Brien with National Weather Service's Anchorage office.
"What's unusual about this storm, though, is this is something we would typically see in the fall," O'Brien said.
