ANCHORAGE, Alaska — The National Weather Service warned that sea ice could close off Point Barrow as early as Friday.
The storm moving over the eastern Bering Sea and Western Alaska will track northeast and move a front east of Point Barrow on late Friday or early Saturday.
Sea ice following the front will move quickly into the Barrow area and close Point Barrow to marine traffic.
NWS said mariners attempting to transit between the Chuckchi and Beaufort seas should make preparations for changing ice conditions.
NWS said smaller concentrations of ice may move into the frontal passage.
More updates will be available on Thursday.
