SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-

.SYNOPSIS...Strong high pressure to our north will maintain
persistent northeast winds of 15-20 knots with higher gusts and seas
of 3-6 feet off the coast. As a result, a Small Craft Advisories
remain in effect this morning with another advisory tonight. By the
end of this weekend, winds should begin to relax some as high

winds and seas by mid week behind the front.
