A cold front will continue to push through the coastal waters today.
Northerly winds will strengthen behind the front to 15 to 25 knots
and then continue into Monday. By Monday night, high pressure moving
over the waters will allow the winds to relax back to 10 to 15 knots
and also shift winds to the northeast and eventually southeast.

into the middle of next week.
