National Weather Service - Alaska Sea Ice Program
324 PM AKDT Monday 10 November 2025

FORECAST VALID...Saturday 15 November 2025

ANALYSIS CONFIDENCE...Moderate.

SYNOPSISA low over the Y-K Delta weakens as a stronger low pressure
system near the Kamchatka Peninsula pushes its front across the
Bering Sea on Tuesday. Overall, low pressure will persist across the
Bering Sea and Gulf of Alaska while high pressure lingers over the
High Arctic, Chukchi Sea, and Beaufort Sea through the forecast
period.

-BEAUFORT SEA-

PKZ505-Central US Arctic Offshore-
PKZ510-Eastern US Arctic Offshore-

Ice covered.

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-

The main ice edge in the Beaufort Sea extends from 71 52N 154 54W
to 71 12N 152 7W to 70 36N 148 2W to 70 59N 152 13W to 71 21N
154 53W. The ice edge is open water.

From land-based points in Alaska, the main ice edge in the Beaufort
Sea extends from 45 nm north of Ikiak to 23 nm north of Cape Halkett
to 132 nm east of Ikiak to 10 nm north of Cape Halkett to 15 nm
north of Ikiak. The ice edge is open water.

FORECAST FOR THE BEAUFORT SEA (DAYS 1 through 5)...Forecast
confidence is high. Northeasterly winds will persist through
Saturday, and sea ice is expected to drift southwest approximately 5-
10 nm per day. The cold airmass anticipated throughout the forecast
period will likely cause the Beaufort Sea to completely freeze over.

PKZ858-Cape Beaufort to Point Franklin from 15 to 85 nm-
PKZ859-Point Franklin to Cape Halkett from 15 to 75 nm-

The main ice edge in the Chukchi Sea extends from 71 52N 154 54W
to 72 42N 158 3W to 70 56N 163 55W to 72 23N 168 51W to 71 6N
171 24W to 70 2N 177 8W to 67 38N 167 57W to 66 7N 169 39W.
The ice edge is open water. There is also ice along the coast from
Cape Lisburne through the North Slope, as well as within Kotzebue
Sound.

From land-based points in Alaska, the main ice edge in the Chukchi
Sea extends from 45 nm north of Ikiak to 95 nm north-northwest of
Ikiak to 170 nm west of Ikiak to 210 nm north of Cape Lisburne to
165 nm north-northwest of Cape Lisburne to 235 nm northwest of Cape
Lisburne to 75 nm west of Kivalina to 150 nm southwest of Kivalina.
The ice edge is open water. There is also ice along the coast from
Cape Lisburne through the North Slope, as well as within Kotzebue
Sound.

FORECAST FOR THE CHUKCHI SEA (DAYS 1 through 5)...Forecast
confidence is high. Generally northeasterly winds will persist
through Saturday, and sea ice is expected to drift southwest
approximately 10-15 nm per day. Sea ice within the main ice pack,
along the ice edge, along the west/northwest coast of AK, and within
Kotzebue Sound is expected to continue growing throughout the
forecast period.

-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-

FORECAST FOR THE BERING SEA (DAYS 1 through 5)...Forecast confidence
is moderate. A low over the Y-K Delta coast is producing easterly
winds across Norton Sound and generally northerly winds across the
remainder of the Bering Sea. On Wednesday, winds become widespread
easterly. Then, winds shift northerly to northeasterly on Friday and
Saturday. Sea ice lingers along the Y-K Delta coast and within
Norton Sound. Expect sea ice to grow especially within Norton Sound
during the forecast period.
