National Weather Service - Alaska Sea Ice Program
423 PM AKDT Friday 14 June 2024

FORECAST VALID...Wednesday 19 June 2024

ANALYSIS CONFIDENCE...High to moderate.

SYNOPSIS...High pressure will remain over the High Arctic through
Saturday. A weak low pressure will form in the western Chukchi Sea
on Saturday morning and then move toward the Beaufort Sea over the
weekend. On Monday, the low dissipates and high pressure builds
across the Chukchi and Beaufort Seas again through Wednesday.

The main ice edge extends from near Wales to 63 48`N 168 33`W to 62
51`N 167 3`W to 62 17`N 170 18`W to 64 48`N 170 22`W to 64 24`N 172
22`W and westward into Russian waters. The ice edge is open water.

From land-based points in Alaska, the main ice edge extends from
near Wales to 105 nm S of Wales to 93 nm SE of Savoonga to 84 nm S
of Savoonga to 65 nm N of Savoonga to 40 nm SW of Gambell and
westward into Russian waters. The ice edge is open water.

-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-

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. Easterly winds will generally persist through
the weekend and into next week, so the ice pack will continue to
consolidate and move west. 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)...Southerly winds
will begin to shift more southwesterly by the end of the weekend.
Thus, the large polynya on the northwest coast will continue to move
north with the southerly winds. Southerly winds will also loosen up
the pack ice around the Wales to Shishmaref coastline. By next week,
winds will likely decrease and become lighter and variable, having a
lesser impact on ice pack movement.

-BERING SEA-

PKZ763-Kuskokwim Delta and Etolin Strait out to 15 nm-

PKZ852-Norton Sound greater than 15 nm-
PKZ853-Kwemeluk Pass to Kwikpak Pass from 15 to 90 nm-

FORECAST FOR THE BERING SEA (DAYS 1 through 5)...Ice south of the
Strait and near St. Lawrence Island will continue to melt to the
north and move with currents and tides. Some areas of marginal ice
coverage will likely remain near Russia and St. Lawrence into next
week.
