Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
225 PM EDT Thu Oct 1 2026

.SYNOPSIS...

High pressure stretching across the coastal Carolinas will move
offshore this afternoon, with prevailing southeasterly winds
expected to surge this evening, but speeds are forecast to remain
just below Caution levels. A surge of tropical moisture will spread
northward from the Florida peninsula tonight and Friday, resulting
in gradually increasing chances for showers and a few embedded
thunderstorms across our local waters. A frontal boundary will then
enter the southeastern states on Friday night and Saturday, with
this boundary slowing its forward progress as it approaches our
local waters through Monday. Coverage of showers and thunderstorms
will continue to increase this weekend. By early next week, strong
high pressure building over the Great Lakes and Mid Atlantic region
will wedge down the southeastern seaboard coast, pushing the front
southward across the northeast Florida waters by Monday night and
providing a surge of northeasterly winds and building seas by early
Tuesday. Small Craft Advisory conditions are likely by late Monday
night or Tuesday, with the potential for wind gusts near Gale force
through at least midweek.
