FORECAST VALID...Wednesday 19 November 2025

ANALYSIS CONFIDENCE...Moderate to high.

SYNOPSISWidespread high pressure over the High Arctic, Beaufort
Sea, and northern Chukchi Sea, and low pressure over the Bering Sea
and southern Chukchi Sea will persist through Sunday. From Monday
through Wednesday, various lows over the Bering Sea will gradually
spread low pressure northward across the Chukchi and Beaufort Seas.

-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-
PKZ859-Point Franklin to Cape Halkett from 45 to 80 nm-
PKZ860-Cape Halkett to Flaxman Island from 45 to 80 nm-
PKZ861-Flaxman Island to Demarcation Point from 45 to 80 nm-

Ice covered.

FORECAST FOR THE BEAUFORT SEA (DAYS 1 through 5)...Forecast
confidence is high. The Beaufort Sea is now completely ice covered.
Northerly to northeasterly winds will become light and variable
Sunday due to a weak low forming. On Monday, easterly winds develop
and then shift southeasterly by Wednesday. Expect sea ice
concentrations to continue increasing within the ice pack as new ice
fills in, as well as for sea ice to drift southward through
Saturday. From Monday through Wednesday, expect sea ice to drift
westward approximately 5-10 nm per day. Southeasterly winds on
Wednesday may promote small polynya formations off of shorefast ice
along the North Slope coast.

-CHUKCHI SEA-

PKZ505-Central US Arctic Offshore-
PKZ808-Cape Espenberg to Motherwood Point out to 10 nm-
PKZ809-Motherwood Point to Cape Krusenstern out to 10 nm-

PKZ855-Kotzebue Sound greater than 10 nm-

Ice covered.

PKZ500-Western US Arctic Offshore-
PKZ807-Wales to Cape Espenberg 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-
PKZ856-Wales to Cape Thompson greater than 15 nm-
PKZ857-Cape Thompson to Cape Beaufort from 15 to 85 nm-

The main ice edge in the Chukchi Sea extends from 68 31N 167 13W
to 70 37N 162 30W to 71 44N 168 59W to 70 38N 177 42W to 68
39N 173 55W and back to 68 31N 167 13W. There is also an ice
edge that extends from near Wales to 66 41N 164 25W to 67 43N 166
8W to 67 19N 166 18W to 67 22N 169 24W and continues into
Russian waters. The ice edge is open water.

From land-based points in Alaska, the main ice edge in the Chukchi
Sea extends from 30 nm southwest of Cape Lisburne to 125 nm
northeast of Cape Lisburne to 175 nm north of Cape Lisburne to 250
nm northwest of Cape Lisburne to 165 nm west-northwest of Cape
Lisburne and back to 30 nm southwest of Cape Lisburne. There is also
an ice edge that extends from near Wales to 60 nm south of Kivalina
to 35 nm west of Kivalina to 45 nm southwest of Kivalina to 110 nm
west of Kivalina and continues into Russian waters. The ice edge is
open water.

FORECAST FOR THE CHUKCHI SEA (DAYS 1 through 5)...Forecast
confidence is high. Northeasterly winds will generally persist
through Wednesday. Thus, sea ice is expected to drift southwest
approximately 10-15 nm per day. Overall, expect sea ice growth
throughout the forecast period, including along the main ice edge,
along the AK coast, and within Kotzebue Sound.

-BERING SEA-

PKZ762-Bristol Bay from Cape Chichagof to Cape Pierce out to 15 nm-
PKZ763-Kuskokwim Delta and Etolin Strait out to 15 nm-
PKZ801-Etolin Strait to Dall Point out to 15 nm-
PKZ802-Dall Point to Kwikpak Pass out to 15 nm-
PKZ803-Kwikpak Pass to Cape Stephens out to 15 nm-
PKZ804-Cape Stephens to Moses Point out to 15 nm-
PKZ805-Moses Point to Sledge Island out to 15 nm-
PKZ806-Sledge Island to Wales out to 15 nm-
PKZ852-Norton Sound greater than 15 nm-

The main ice edge in the Beaufort Sea begins near Wales and extends
northeast into the Chukchi Sea. There is also ice along the Y-K
Delta coast, within Norton Sound, near Port Clarence, and southern
portions of Saint Lawrence Island.

FORECAST FOR THE BERING SEA (DAYS 1 through 5)...Forecast confidence
is moderate. Northeasterly winds become light and variable briefly
on Saturday morning before becoming moderate easterly winds through
approximately Sunday. A low over the eastern Bering Sea is expected
to bring southerly winds to the Y-K Delta coast on Monday while
northeasterly winds develop for the Norton Sound and Seward
Peninsula regions. By Wednesday, southeasterly winds spread to the
Norton Sound and Seward Peninsula areas while northeasterly winds
continue through the Bering Strait. Periods of southeasterly winds
will likely melt any existing ice, especially along the Y-K Delta
coast and northern Bristol Bay coast. Sea ice is expected to
continue to grow within Norton Sound and along the coast from Wales
to the Port Clarence area.
