Golovin Bay as well as along the Yukon River Delta.

FORECAST FOR THE CHUKCHI SEA (Days 1 through 5)...Northeasterly
winds will persist over the Chukchi Sea through Monday. The ice pack

FORECAST FOR THE BERING SEA (Days 1 through 5)...Generally northerly
winds will persist through the Bering Strait and northern Bering Sea

away from the remaining coastal ice and drift into open water
farther offshore, but will then melt fairly quickly as it encounters
warmer sea surface temperatures.
