Synopsis for the coastal waters from Bonita Beach to Suwannee River-
1027 AM EDT Sun Jun 29 2025

.SYNOPSIS...

As extra moisture streams into the area, showers and thunderstorms
will increase in coverage and frequency over the next few days.
Mariners should expect hazardous winds and seas in the vicinity of
these storms, along with reduced visibility. Weather conditions
become even more poor by late week as a weak frontal boundary
falls apart over the N Gulf, leading to higher winds and seas,
along with widespread thunderstorm activity.
