Synopsis for the coastal waters from Bonita Beach to Suwannee River-
353 AM EDT Mon May 12 2025

.SYNOPSIS...
A weak cold front in the Gulf has brought deep tropical
moisture and breezy conditions out of the south. Winds will be
between 10 to 15 knots today with widespread showers and isolated
thunderstorms. The front will be pushing through the state by Monday
evening which will help to start drying us out and helping to bring
wind speeds down. Winds are expected to be out of the south and
southwest for the rest of the week around 5 to 10 knots.
