Synopsis for the coastal waters from Bonita Beach to Suwannee River-
252 AM EDT Thu Oct 9 2025

.SYNOPSIS...
The pressure gradient will increase today between strong high
pressure down the Eastern Seaboard and the combination of a stalled
frontal boundary across North Florida and a tropical wave in the
Northern Caribbean Sea to produce increasingly gusty northeast to
east winds over parts of the coastal waters with impactful SCEC
levels today becoming hazardous SCA conditions this evening
through Friday for dangerous marine conditions for small craft
into the weekend as a cold front moves through the waters.
