early today. A wave of low pressure will then develop along this

this afternoon through tonight. Low pressure will move offshore
Monday morning, resulting in breezy northwest winds. Northerly winds
then strengthen with building seas to Small Craft Advisory levels
early next week. Weak high pressure will build over the area by
Wednesday and then shift southeast of the forecast area on Thursday
as another cold front approaches from the northwest.
