The main ice edge extends from near Quinhagak to 56 42N 169 3W to
57 16N 172 26W to 60 15N 179 39W and continues into Russian
waters. The ice edge is open water.

From land-based points in Alaska, the main ice edge extends from
near Quinhagak to 20 nm northeast of Saint George to 100 nm
northwest of Saint George to 300 nm southwest of Gambell and
continues into Russian waters. The ice edge is open water.

FORECAST FOR THE BERING SEA (DAYS 1 through 5)...Forecast confidence
is high. Southerly to easterly winds will persist over much of the
