220 PM AKDT Monday 24 June 2024

FORECAST VALID...Saturday 29 June 2024

ANALYSIS CONFIDENCE...High.

SYNOPSIS...High pressure over the Beaufort Sea will move east into
the Canadian Archipelago as weak lows move into the Chukchi. A
seasonally strong low pressure system enters the Bering Sea on
Wednesday and lingers through Saturday.


From land-based points in Alaska, the main ice edge extends from
near Wales to 80 nm S of Pt Hope to 50nm NW of little diomede and
continues westward in Russian waters. The ice edge is open water.
There is also some areas of brash ice remaining to the northeast of
Saint Lawrence Island.

The main ice edge extends from near Wales 67 17`N 168 29`W to 66

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.

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-

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-

PKZ806-Sledge Island to Wales out to 15 nm-
PKZ816-South side of Saint Lawrence Island out to 15 nm-
PKZ817-North 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.
