FORECAST FOR THE BEAUFORT SEA (DAYS 1 through 5)...Forecast
confidence is high. Westerly winds will persist through Friday, then
winds will be light and variable across the southern Beaufort Sea
Saturday through Monday. Expect ice to drift eastward through Friday
on the order of 5-10 nm/day, then sea ice will drift with local
tides and currents through Monday. Near shore ice will continue to
degrade from the shore. Expect the melt area from the Mackenzie
River Delta to continue to make westward progress through the
forecast period.

FORECAST FOR THE CHUKCHI SEA (DAYS 1 through 5)...Forecast
confidence is moderate. Generally southerly winds will hasten melt
in the southern Chukchi Sea through Friday, then winds will shift to
northerly through the weekend. A band of remaining pack ice will
likely remain along the coast between Cape Krusenstern and Point
Hope, but as northerly winds develop that band of ice will likely
move away from the coastline. The ice edge will likely move to the
north up to 20 nm through Friday, then move back to the south up to
20 nm Saturday through Monday.

-BERING SEA-

PKZ817-North side of Saint Lawrence Island out to 15 nm-

FORECAST FOR THE BERING SEA (DAYS 1 through 5)...A small area of
brash ice remains northeast of Saint Lawrence Island, which will
melt completely by the weekend. Otherwise, Alaska waters of the
Bering Sea are ice free.
