The ice edge is open water. FORECAST FOR THE BERING SEA (DAYS 1 through 5)...Forecast confidence is high. North to northwest winds will persist through Wednesday across the Bering Sea ice pack. Polynyas will continue to expand and will generally remain open, especially south of Saint Lawrence Island and in eastern Norton Sound. Sea ice will reach Saint Paul Island and may reach Saint George Island during the forecast period, though sea ice will be melting as it drifts into the warmer waters in the area of the Pribilof Islands. The ice pack overall will continue to melt and sea ice concentrations will decrease as the sea ice moves southeast approximately 15 nm per day through the forecast period. && Schreck
