FORECAST FOR THE CHUKCHI SEA (DAYS 1 through 5)...Forecast
confidence is high. Wind direction will be predominately northerly
through Monday, which will move existing ice to the south around 10-
15 nm/day. On Tuesday and Wednesday southerlies return which will
move ice back northward around the same rate. Expect the appendage
of marginal ice extending from the Russian coast to largely melt in
the next week.
