Sunday evening another potent low will lift into the gulf of
Alaska bringing strong gales to storm force winds to the northern
Outer Coast. After coordination with both the Ocean Prediction
Center and Anchorage Weather Forecast Office, there is high
confidence for sustained easterly storm force winds near Cape St.
Elias, with easterly strong gales, gusting to storm force, likely
for areas south of Cape Suckling. Along the Southeast Alaska
coastal waters, especially near Yakutat and Cape Fairweather,
winds will increase to gale force winds of 35 kts Monday. Winds
will increase Sunday night, with winds reaching peak intensity
Monday morning. Associated with these winds will be easterly fresh
seas of 16 to 20 ft south of Cape Suckling, with 20 to 25 ft seas
moving towards the Kenai.
