SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
328 AM EDT Fri Oct 20 2017

.SYNOPSIS...Strong high pressure to the north will be the dominant surface
feature influencing the weather over the coastal waters for the next
several days. Storm/rain chances will be very low, but the main
marine concern will be gusty east-northeast winds reaching small
craft advisory level at times over the next couple of days. The
weather pattern will change by the beginning of next week as a cold
front approaches the area. Winds will shift to the south by the
Monday ahead of the front and rain/storm chances will be on the
increase. Winds will further shift to the north-northwest by the
middle of next week in the wake of this front. Drier air and
decreasing rain chances expected into next week. No other marine
impacts expected.
