Synopsis for the coastal waters from Bonita Beach to Suwannee River-
245 PM EDT Mon Sep 1 2025

.SYNOPSIS...

Breezy northeasterly winds will continue through tonight with
conditions possibly approaching Small Craft Advisory for a brief
period across the northern Gulf waters, though the duration looks
rather limited so will maintain small craft exercise cautions
conditions. NE winds should fall below 15 kts on Tuesday before
weakening further into mid to late week as the pressure gradient
relaxes. In addition, seas will also gradually subside throughout
the week with 2-4 foot seas through tonight across northern marine
waters before falling to 2 ft or less by Tuesday evening and will
continue to gradually less into late week. Otherwise, daily
chances for showers and storms will persist throughout the week
with highest rain chances across central and southern Gulf waters
at times as deeper moisture lingers in these areas.
