Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
224 PM EDT Wed Jun 24 2026
.SYNOPSIS...
A weakening frontal boundary positioned over the northeast Florida
waters will dissipate tonight. Isolated showers and thunderstorms
will be possible this evening, mainly for the waters south of St.
Augustine. A weak pressure pattern will continue through Thursday,
allowing for the Atlantic sea breeze to move onshore during the
early evening hours. Atlantic high pressure will then extend its
axis westward across the Florida peninsula from Friday through
Sunday, creating a prevailing westerly wind flow during the
overnight and morning hours, with winds becoming onshore each
afternoon as the Atlantic sea breeze moves inland. Scattered showers
and thunderstorms are expected to impact our local waters during the
late afternoon and evening hours each day from Thursday through
Sunday. A surface trough will then press southward across our area
on Monday, providing an increasing coverage of showers and
thunderstorms. Northeasterly winds will develop by Monday night and
Tuesday as this trough shifts southward and high pressure builds
over the southeastern states, with breezy conditions possible by
Tuesday afternoon.
