Synopsis for the coastal waters from Bonita Beach to Suwannee River-
1016 AM EDT Wed Jun 4 2025

.SYNOPSIS...

Unsettled weather continues across coastal waters as an upper-level
low spins in the NE Gulf. Seas have been building in response to
conditions, driven by winds of 15 to 20 knots. Small craft should
exercise caution until conditions improve. Showers and thunderstorms
will continue to remain possible at anytime through the work week as
WSW flow continues, even as the low pulls away. Quieter weather will
return for the weekend before becoming unsettled again into next
week.
