Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
422 AM EDT Tue Mar 31 2026
.SYNOPSIS...
High pressure centered near Bermuda will continue to extend its
axis across the southeastern states, maintaining persistent
onshore winds and elevated seas, especially for the offshore
waters. Small Craft Advisory level seas expected to redevelop over
the offshore waters adjacent to northeast Florida on Thursday
afternoon and evening, where seas will slowly build through the
upcoming weekend. Elevated seas will expand to the near shore
waters adjacent to northeast Florida on Thursday night and Friday,
and Small Craft Advisories may develop over these near shore
waters by late in the weekend. Meanwhile, an inverted trough will
approaching our waters from the east late on Wednesday night,
generate scattered showers and thunderstorms throughout our local
waters on Thursday. Isolated showers and thunderstorms will remain
possible late this week and through the weekend in the breezy
onshore flow pattern. A cold front will then enter the
southeastern states late this weekend, likely crossing our local
waters on Monday, accompanied by showers and thunderstorms.
