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-

PKZ806-Sledge Island to Wales out to 15 nm-
PKZ816-South side of Saint Lawrence Island out to 15 nm-

PKZ850-Etolin Strait to Kwemeluk Pass from 15 to 90 nm-
PKZ851-Southwest of Saint Lawrence Island from 15 to 100 nm-
PKZ853-Kwemeluk Pass to Kwikpak Pass from 15 to 90 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 mid-week. An area of
brash ice will linger northeast of Saint Lawrence Island through
Wednesday.
