Synopsis for the coastal waters from Bonita Beach to Suwannee River-
211 AM EDT Sun Aug 3 2025

.SYNOPSIS...

Isolated to scattered thunderstorms will continue to be favored
during the overnight and morning hours across coastal waters
through the remainder of the weekend. As high pressure re-centers
over the Florida peninsula during the week, the overall flow will
become even lighter and more variable, favoring almost calm seas
that are less than a foot. In response to this change,
thunderstorms will be more likely near the coast in the afternoon,
with the potential for some of these storms to drift offshore
during the evening hours by the middle of the week.
