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-

FORECAST FOR THE BEAUFORT SEA (DAYS 1 through 5)...Forecast
confidence is high. Moderate westerly winds will likely stall or
reverse the Beaufort Gyre through Friday, areas closer to the Alaska
coast could see eastward movement of the pack ice 5-10 nm/day. The
pack ice will also move closer to the coast. Saturday through
Monday, westward movement of ice will continue 10-15 nm/day, along
with local tides and currents.


-CHUKCHI SEA-


PKZ500-Western US Arctic Offshore-
PKZ505-Central US Arctic Offshore-
PKZ813-Point Franklin to Cape Halkett out to 15 nm-
PKZ859-Point Franklin to Cape Halkett from 15 to 75 nm-


Ice covered.


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-
PKZ857-Cape Thompson to Cape Beaufort from 15 to 85 nm-
PKZ858-Cape Beaufort to Point Franklin from 15 to 85 nm-


The main ice edge extends from near Kivalina to 68 19N 167 43W to
69 1N 169W and continues west into Russian waters. The ice edge is
open water.


From land-based points in Alaska, the main ice edge extends from
near Kivalina to 20 nm west of Point Hope to 70 nm west of Cape
Lisburne and continues west into Russian waters. The ice edge is
open water.


FORECAST FOR THE CHUKCHI SEA (DAYS 1 through 5)...Forecast
confidence is high. Northerly winds will persist through Friday then
go light and variable through Monday. The ice in the vicinity of
Cape Lisburne looks to be melting very quickly the last few days. It
should be mostly melted by Monday, however there will probably be
some low concentration marginal ice or open water remaining to the
northwest of Cape Lisburne. Otherwise expect the ice edge to retreat
to near Point Franklin westwestard into Russian waters. Thursday and
Friday, northwesterly winds will push the pack ice against the coast
from Wainwright to Utqiagvik.
