JUNEAU - The National Weather Service issued a strong wind advisory effective until 6 p.m.
Forecasters called for east winds of 25 mph today with gusts to about 45. The wind would exacerbate already cold temperatures, creating a wind chill factor of 20 below this morning, the service said.
Tonight, lows are expected to be zero to 6 degrees, while wind gusts could reach 40 mph. The wind chill factor could drop to 25 below.
While winds may die down late tonight or early Monday, cold temperatures are expected to remain until the middle of the week, said meteorologist Andy McLaurin.
A tight pressure gradient between two weather systems over British Columbia is causing winds, while an arctic front located south of Juneau brings cold air in from the north.
"Unfortunately, it's going to be a slow process for temperatures to rebound," McLaurin said. "The arctic air mass is going to stay in place for awhile."
By mid-week, the service is forecasting temperature highs in the mid-20s and lows in the teens.
