A forecast of blowing snow and limited visibility prompted the National Weather Service to issue a blizzard warning for the Western Prince William Sound from midnight to 7 p.m. Friday.
Some 6 to 13 inches of snow was predicted for cities including Whittier, Seward, Girdwood and Moose Pass by Friday evening, said meteorologist Bill Ludwig.
Snow should begin around midnight with gusty winds picking up soon after. South of Moose Pass to Seward face the main threat of a blizzard, he said.
Wind gusts in those areas may reach 40 mph and blowing snow could limit visibility to one-quarter mile or less, the weather service said.
"This will lead to white-out conditions ... making travel very difficult," the warning said. "All travel and outdoor activity is strongly discouraged."
