164.4W to 68.3N 167.3W to 70.2N 164.2W to 69N 170.9W to 67.3N 167.9W
to 66.5N 169.8W to 65.9N 169W to 64.3N 172.8W. The ice edge is
mainly open water. There is additional sea ice within Norton Bay and
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
is expected to shift to the southwest by 20 to 30 nm through
Monday.

FORECAST FOR THE BERING SEA (Days 1 through 5)...Generally northerly
winds will persist through the Bering Strait and northern Bering Sea
through Monday. The remaining coastal ice within the Bering Sea will
continue to deteriorate through Monday. Strips of ice may be pulled
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.
