The National Weather Service warned Thursday of hurricane-force winds with hazardous conditions for mariners in the North Pacific.
The agency’s Ocean Prediction Center said offshore winds Thursday could reach 90 mph, with waves to 50 feet or higher.
The storm was heading northeast toward Alaska's Aleutian Islands but expected to weaken as it approached land.
As of 11 a.m., the storm center was about 1,500 miles southwest of Anchorage.
Marine forecaster Jim Nolt says the storm center was moving at 10 mph and could reach the Aleutians by Friday afternoon.
NWS forecaster Michelle McAuley in Anchorage said the main impact was predicted to be offshore.
Nolt says Aleutian communities could see winds approaching 60 mph.
