Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
848 PM EDT Thu Apr 2 2026
.SYNOPSIS...
Small Craft Exercise Caution level seas are expected over the
offshore waters adjacent to northeast Florida 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 early 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 northeast
winds and building seas across our local waters, with Small Craft
Advisory conditions becoming increasingly likely for much of the
week.
