SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
847 PM EDT Thu Aug 17 2017

.SYNOPSIS...Surface high pressure will remain across the region with
generally light winds and seas. Winds will turn onshore each
afternoon with the seabreeze. Winds may increase a bit with easterly
surges early next week as the pressure gradient tightens between low
pressure to the south and high pressure to the north. Otherwise, the
only marine concern will be scattered overnight and early morning
thunderstorms which may lead to locally stronger winds and rougher
seas.
