Synopsis for the coastal waters from Bonita Beach to Suwannee River-
1018 AM EDT Mon Aug 4 2025

.SYNOPSIS...

Isolated to perhaps scattered coastal storms are possible mainly
this morning before the bulk of the activity transitions inland by
early afternoon as light S to SSW flow continues across coastal
waters. This pattern will continue for the next couple days, with
the best potential for storms across coastal waters in the early
morning hours. With winds of 5 to 10 knots, seas should continue to
remain around 2 feet or less through the middle of the week. The
potential for more storms will increase across coastal waters as the
weekend approaches.
