Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
227 AM EDT Sat Apr 25 2026
.SYNOPSIS...
High pressure situated offshore of the southeastern states today
will continue to gradually weaken as it shifts eastward. A cold
front will then enter the southeastern states later today, possibly
helping to develop scattered late afternoon and evening showers and
isolated thunderstorms across our local waters this weekend.
This cold front will cross our local waters on Sunday night, with
low pressure along this front strengthening somewhat off the
Carolina coast by Monday. Winds will shift to northerly on Sunday
night and then northeasterly by Monday morning, with Caution
conditions likely due to breezy speeds and building seas through
Monday evening. Weak high pressure will then briefly build over our
local waters on Tuesday and Wednesday. Another cold front will then
approach our area from the northwest late next week.
