SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
250 PM EST Mon Dec 18 2017

.SYNOPSIS...
High pressure will remain over the waters over the next couple of
days with light east to southeast winds shifting onshore in the
afternoon due to the seabreeze. A cold front will move across the
northern waters late Wednesday into Thursday, turning winds to the
southwest. Moisture pooling ahead of this front may allow for periods
of sea fog, especially over the northern waters and near the Florida
Big Bend, though some potential will also exist further south. High
pressure will fill in behind the front with light winds and seas 2
feet or less expected into the weekend.
