SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
838 PM EDT Mon Aug 21 2017

.SYNOPSIS...
A slight increase in the pressure gradient will enhance easterly
surges over the Gulf waters between a weak tropical wave moving into
the Gulf of Mexico, the Bermuda high pressure ridge axis nudging into
the area, and another tropical wave over the Bahamas. The gradient
relaxes as high pressure settles over the region for the end of the
week. Expect scattered to numerous storms Tuesday into late week as
well.
