SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
904 PM EDT Wed Oct 18 2017

.SYNOPSIS...Strong high pressure to our north will maintain persistent
northeast winds of 15-20 knots with higher gusts and seas of 3-5
feet off the coast. As a result, a Small Craft Advisory is in effect.
By the end of this weekend, winds should begin to relax some as high
pressure slides off to our east and winds veer to a more southerly
component. A cold front will then approach the area early in the work
week with the potential of high winds and seas by mid week.
