Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
224 PM EDT Sat Mar 14 2026
.SYNOPSIS...
A stationary frontal boundary situated over south Florida will lift
northward as a warm front tonight, with a few showers and possibly
an embedded thunderstorm developing after midnight tonight across
the northeast Florida waters. Easterly winds will shift to
southeasterly on Sunday, with breezy conditions developing over the
northeast Florida waters by Sunday afternoon. Showers and
thunderstorms will increase in coverage on Sunday afternoon and
evening as the warm front lifts northward. Meanwhile, a strong cold
front will enter the southeastern states on Sunday night. Southerly
winds will strengthen to Caution levels on Sunday evening across our
local waters ahead of this approaching front, with Small Craft
Advisory conditions potentially developing offshore after midnight.
Strong to severe thunderstorms will be possible on Monday as the
strong cold front crosses our local waters. Stronger storms will be
capable of producing strong wind gusts, frequent lightning strikes
and possible waterspouts. Small Craft Advisory conditions will
overspread our local waters early in the day, with gusty southerly
winds shifting to southwesterly by early afternoon and then westerly
during the evening hours in the wake of the frontal passage. Showers
and thunderstorms will push away from our local waters on Monday
night, with strong northwesterly winds developing towards midnight
as high pressure builds over the lower Mississippi Valley.
Occasional gusts to Gale Force may be possible overnight, with Small
Craft Advisory conditions continuing through Tuesday morning before
winds shift to northerly during the afternoon hours. High pressure
building across the southeastern states on Tuesday night and
Wednesday will allow winds to shift to northeasterly, with breezy
conditions keeping Caution conditions in place through at least
midweek.
