The ice edge extends from Point Barrow to 71.4N 155.2W to 71.7N 156W
to 71.3N 162.2W to 72.2N 161.2W to 73.1N 175.5W and continues in
Russian waters. The ice edge is mainly open water.

FORECAST FOR THE CHUKCHI SEA (Days 1 through 5)...Generally easterly
winds will persist through Wednesday. Sea ice will spread out as it
drifts westward, and some ice will continue to melt as it reaches
the much warmer open waters in the Chukchi Sea. The overall ice edge
is expected to move westward 10 to 20 nm through Wednesday.

-Beaufort Sea-

FORECAST FOR THE BEAUFORT SEA (Days 1 through 5)...Light winds will
persist through Monday, then moderate easterly winds will develop
Tuesday through Wednesday. Sea ice will continue to melt within the
ice pack north of approximately 73N, while sea ice south of 73N will
continue to melt much slower due to thicker first year and multi-
year ice in the area.
