SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
1013 AM EST Sun Jan 21 2018

.SYNOPSIS...With surface high pressure to our north, winds will
generally be out of the northeast between 5-15 knots before taking an
onshore component near the coast in the afternoon due to the
development of a weak seabreeze. No headlines are expected over the
next few days. Winds will veer to the southeast on Monday and
Tuesday ahead of an approaching cold front. Due to cold sea surface
temperatures, increasing moisture ahead of the front will create the
possibility for sea fog, especially Monday night into Tuesday. Later
in the work week, easterly winds will increase to possible
cautionary/advisory levels as a north oriented pressure gradient
tightens.
