The main ice edge extends from near Egegik to Cape Newenham to 61
6`N 166 6`W to 62 13`N 167 10`W to 63 59`N 165 31`W to 64 13`N 166
59`W to 66 37`N 168 46`W to 67 3`N 164 51`W to 68 16`N 168 8`W to 65
51`N 169 21`W to 64 17`N 172 0`W and into Russian Waters. There is a
fairly large area of ice-free water 45 nm west of Icy Cape. There is
some ice along the coast of Saint Lawrence Island.

From land-based points in Alaska, the main ice edge extends from
near Egegik to Cape Newenham to 20 nm W of Hooper Bay to 45 nm W of
Kwikpak to 30 nm S of Nome to 10 nm E of Little Diomede to 55 nm N of
Diomede to 35 nm S of Kivalina to 30 nm W of Pt Hope to 10 nm W of
Diomede to 35 nm NW of Gambell and into Russian Waters. There is a
fairly large area of ice-free water 45 nm west of Icy Cape. There is
some ice along the coast of Saint Lawrence Island.

FORECAST FOR THE BEAUFORT SEA (Days 1 through 5)...Southwesterly
winds have moved into the area today and will transition to stronger
southeasterlies on Sunday, potentially opening polynyas along the
coast/shorefast ice. By midweek winds look to calm, which should
promote ice growth in polynyas.

FORECAST FOR THE CHUKCHI SEA (Days 1 through 5)... Southerly winds
will pick up this evening as a system moves north into the Chukchi
over the weekend. This may retreat the ice edge 15 to 25 nm north
and compact the ice that rapidly formed this week. However, arctic
air on the back side of the system will encourage fast recovery and
ice movement back to the east the same amount. There will still
likely be some ice free areas left off of the NW coast of Alaska as
well as the Bering Strait region.


FORECAST FOR THE BERING SEA (Days 1 through 5)...Southerly winds
currently over the area will once again cause ice in Norton Sound to
push north into the coast and eventually to the northwest as winds
become southeasterly on early Sunday. A brief period of cooler
westerly flow may help promote growth and movement back to the east
through Tuesday morning before easterly to southeasterly flow
returns. Ice to the south of Hooper Bay also has a decent chance of
melting out or pushing up against the coast through Wednesday


-Cook Inlet-

PKZ130-West of Barren Islands Including Kamishak Bay-
PKZ139-Cook Inlet Kalgin Island to Pt. Bede-
PKZ140-Cook Inlet North of Kalgin Island-

ANALYSIS CONFIDENCE...Moderate.

The main ice edge in Cook Inlet is from the West Forelands to East
Forelands

SYNOPSIS...Low pressure and offshore flow remain until a front moves
over the area over the weekend.

FORECAST FOR COOK INLET (Day 1 through 5)...Expect favorable growing
conditions over the next five days and advance of the ice edge to
the south 20 to 30 nm through Wednesday.
