the Bering Sea lingers through Monday. High pressure will build over
the southern Chukchi Sea over the weekend.

The main ice edge extends from 65 59N 167 1W to 67 34N 169 45W
to 66 11N 169 11W and continues southward along the Russian coast.
There is also an area of brash sea ice remaining to the northeast of
Saint Lawrence Island.

From land-based points in Alaska, the main ice edge extends from 25
nm southwest of Shishmaref to 80 nm southwest of Point Hope to 30 nm
northwest of Diomede and continues southward along the Russian

-BEAUFORT SEA-

PKZ505-Central US Arctic Offshore-
PKZ510-Eastern US Arctic Offshore-
PKZ813-Point Franklin to Cape Halkett out to 15 nm-
PKZ814-Cape Halkett to Flaxman Island out to 15 nm-
PKZ815-Flaxman Island to Demarcation Point out to 15 nm-
PKZ860-Cape Halkett to Flaxman Island from 15 nm to 80 nm-
PKZ861-Flaxman Island to Demarcation Point from 15 nm to 75 nm-

Ice covered.

FORECAST FOR THE BEAUFORT SEA (DAYS 1 through 5)...Forecast
confidence is high. Light and variable winds will make tides and
currents as well as the Beaufort Gyre the predominant mover for sea
ice. Near-shore ice will continue to degrade.

-CHUKCHI SEA-

PKZ500-Western US Arctic Offshore-
PKZ505-Central US Arctic Offshore-
PKZ807-Wales to Cape Espenberg out to 15 nm-
PKZ808-Cape Espenberg to Motherwood Point out to 10 nm-
PKZ809-Motherwood Point to Cape Krusenstern out to 10 nm-
PKZ810-Cape Krusenstern to Cape Thompson out to 15 nm-
PKZ811-Cape Thompson to Cape Beaufort out to 15 nm-
PKZ812-Cape Beaufort to Point Franklin out to 15 nm-
PKZ813-Point Franklin to Cape Halkett out to 15 nm-
PKZ855-Kotzebue Sound greater than 10 nm-
PKZ856-Wales to Cape Thompson greater than 15 nm-
PKZ857-Cape Thompson to Cape Beaufort from 15 to 85 nm-
PKZ858-Cape Beaufort to Point Franklin from 15 to 85 nm-

Ice covered.

FORECAST FOR THE CHUKCHI SEA (DAYS 1 through 5)...Light and variable
winds will make tides and currents the predominant mover of sea ice
through the period. Expect melt to continue to accelerate in the
southern Chukchi Sea through the period.


-BERING SEA-

PKZ817-North side of Saint Lawrence Island out to 15 nm-
PKZ854-Sledge Island to Wales greater than 15 nm-

FORECAST FOR THE BERING SEA (DAYS 1 through 5)...Alaska waters of
the Bering Sea will largely be sea ice free by late-week. An area of
brash ice will linger northeast of Saint Lawrence Island through
the weekend.
