Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
855 AM EDT Thu Apr 2 2026
.SYNOPSIS...
Small Craft Exercise Caution level seas are expected to develop over
the offshore waters adjacent to northeast Florida this afternoon as
a trough moves westward, increasing wind speeds slightly and
generating scattered showers and a few embedded thunderstorms
through Friday. Elevated seas will persist across the offshore
waters adjacent to northeast Florida through Friday night. A cold
front will enter the southeastern states late this weekend, likely
crossing our local waters on Monday morning, accompanied by showers
and thunderstorms. Strong high pressure building north of the area
will then wedge down the southeastern seaboard during the early to
middle portions of next week, likely create a surge of strong
northeasterly winds and building seas across our local waters, with
Small Craft Advisory conditions becoming increasingly likely for
much of the week.
