225 PM EDT Tue Jul 28 2026

.SYNOPSIS...

Prevailing southwesterly winds are forecast today, with only
isolated afternoon thunderstorms possible over the near shore waters
adjacent to northeast Florida. Wind speeds will increase to Caution
levels early this evening throughout our local waters, with these
stronger speeds continuing through around sunrise on Wednesday. A
frontal boundary will then sink into the Deep South late this week,
with this feature becoming stationary during the weekend. Strong to
severe thunderstorms will be possible well in advance of this front
on Wednesday afternoon and evening, with stronger storms potentially
producing damaging wind gusts, waterspouts, frequent lightning
strikes, and torrential downpours. Scattered to numerous
thunderstorms will continue across the northeast Florida waters on
Thursday and Friday, with less coverage currently forecast for the
Georgia waters. Waves of showers and thunderstorms will then
overspread all of our local waters during the upcoming weekend.
Outside of expected thunderstorm activity, southwesterly winds will
prevail and will strengthen ahead of the approaching front beginning
towards midweek, with Caution conditions likely through the upcoming
weekend.
