Detailed Forecast

High pressure, in addition to inland heating, will drive an increase of winds to 20-25 kts during the daytime hours. This weather pattern will lead to gusty winds in Lynn Canal, Cross Sound, Icy Strait Corridor, near Cape Decision, and in southern Chatham Strait. Wave heights up to 8 ft start to diminish after tomorrow through the next several days.
