The storm was traveling at 60 mph, said Andy Brown, lead National Weather Service forecaster in Anchorage. It could reach the beachfront city of Nome by late Tuesday, with winds hitting 85 mph.
The storm was expected to produce a 10-foot surge, forcing dozens of coastal communities to make emergency preparations. Brown advised Bering Sea mariners and people living in coastal communities from Wales to Unalakleet to "prepare for a really nasty storm."
"It is very dangerous," Brown said. "Everybody is spreading the word to let them know this is a major storm."
That included the Coast Guard. "We are prestaging helicopters from Air Station Kodiak to parts of Western Alaska in response to severe weather advisories including hurricane force winds and high seas that are forecast all along the west coast of Alaska," said Capt. Daniel Travers.
The storm, described by Brown as "big, deep, low," was taking an unusual path through the northern and eastern Bering Sea.
The storm will likely be "life-threatening ... one of the worst on record," the service said.
"Essentially the entire west coast of Alaska is going to see blizzard and winter conditions: heavy snow, poor visibility, high winds," NWS forecaster Bob Fischer told alaskadispatch.com.
