Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
818 AM EDT Mon Mar 30 2026
.SYNOPSIS...
Strong high pressure situated off the New England coast will migrate
slowly east-southeastward through tonight, becoming centered near
Bermuda on Tuesday. This feature will continue to extend its axis
across the southeastern states this week, maintaining breezy
onshore winds, especially offshore. Small Craft Advisory level
seas will continue for offshore waters through early this
evening, with seas then gradually diminishing near shore.
Elevated seas will persist offshore through midweek, with another
round of Small Craft Advisory level seas possible late this week
for the offshore waters adjacent to northeast Florida. Meanwhile,
coastal troughing positioned over the northeast Florida waters
will continue to generate isolated to widely scattered showers,
with a few embedded thunderstorms possible on Tuesday and
Wednesday. This trough will lift northward by midweek, with
another inverted trough then approaching our waters from the east
late this week that will likely generate scattered showers and
thunderstorms.
