Synopsis for the coastal waters from Bonita Beach to Suwannee River-
820 PM EST Sun Nov 23 2025

.SYNOPSIS...
Winds and seas are expected to remain light as a weak cold front
continues to sink south across the E Gulf waters tonight with
winds becoming north to northwest. Areas of sea fog will continue
over the nearshore waters off the Nature Coast and some of this
will spread south into the Tampa Bay area tonight. High pressure
will build back over the waters on Monday with winds shifting to
easterly through Tuesday. A stronger but dry cold front will move
across the waters during midweek. Winds and seas will quickly
increase in the wake of the cold front Thursday with cautionary
levels likely, possibly advisory levels over portions of the
waters Friday into the weekend.
