Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1232 PM EDT Fri Apr 24 2026
.SYNOPSIS...
High pressure situated offshore of the southeastern states will
continue to gradually weaken as it shifts eastward. Onshore winds
will become breezy this afternoon across the near shore waters as
the Atlantic sea breeze boundary shifts inland, followed by winds
shifting to southerly towards sunset this evening and then
southwesterly with gradually decreasing speeds after midnight
tonight. A frontal boundary will then enter the southeastern states
on Saturday, possibly developing widely scattered late afternoon and
evening showers and isolated thunderstorms across our local waters
through the weekend. This front will cross our local waters on
Sunday evening, 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, allowing winds
and seas to subside. A cold front will then approach our area from
the northwest late next week.
