Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
426 AM EDT Sat May 2 2026
.SYNOPSIS...
Low pressure developing along a frontal boundary situated along
the northern Gulf coast will push across our local waters early
this afternoon. Widespread showers and thunderstorms will
overspread our local waters during the late morning and afternoon
hours, with strong to isolated severe storms possible through
around sunset. Stronger storms will be capable of producing strong
wind gusts, frequent lightning strikes, and possibly a few
waterspouts. Southwesterly winds will strengthen after sunrise,
with speeds likely reaching Caution levels as winds shift to
westerly and then northwesterly this afternoon. The front will
shift south of our area tonight, with gusty northerly winds
expected after midnight as lingering showers depart the northeast
Florida waters. Breezy northeast winds are then expected on Sunday
as high pressure builds into the southeastern states, with
diminishing winds and seas expected by early Sunday evening.
High pressure will shift offshore of the southeastern states early
next week, allowing for prevailing southeasterly winds. Breezy
conditions are likely on Wednesday afternoon well in advance of a
cold front that will be entering the southeastern states, with
Caution level speeds possible through Thursday as winds shift to
southerly and then southwesterly. Showers and thunderstorms will
likely accompany this next frontal passage on Thursday afternoon
and evening.
