Synopsis for the coastal waters from Bonita Beach to Suwannee River-
137 PM EDT Tue Sep 2 2025

.SYNOPSIS...

A low pressure system in the Atlantic attached to a stall
front in South Florida will bring us northerly winds through
Wednesday with speeds around 5 to 10 knots. Shower chances will be
lower then normal due to sinking air on the back side of low
pressure system. The low will push away by Thursday but front will
remain. This will shift our winds southeasterly for Thursday and
Friday with speeds remain around 5 to 10 knots. Best chance of
storms will be along the coast in the evening and early overnight
nights.
