AMZ400-121415-
Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
703 PM EDT Mon May 11 2026
.SYNOPSIS...
A cold front will cross the waters adjacent to southeast Georgia
late this evening and then the northeast Florida waters during the
early to mid-morning hours on Tuesday morning. A few strong
thunderstorms could impact the near shore waters late this afternoon
and evening, with frequent lightning strikes and briefly gusty winds
possible. Showers and a few embedded thunderstorms will then
overspread our local waters on Tuesday morning, with periods of
heavier downpours possible through Tuesday night. Meanwhile, high
pressure building over the Ohio Valley and Mid-Atlantic states in
the wake of this frontal passage will send a surge of northeasterly
winds down the southeastern seaboard overnight tonight through
Tuesday morning, with Small Craft Advisory conditions developing
initially across the Georgia waters after midnight and then
expanding to the waters from St. Augustine northward early on
Tuesday morning. Showers and embedded thunderstorms, along with
Small Craft Advisory conditions, will continue through late Tuesday
night across our local waters. Showers may linger through Wednesday
before another high pressure center builds southward from the Great
Lakes states late this week, signaling a drying trend that will
continue across our local waters through the upcoming weekend.
