Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
402 AM EDT Tue Jun 9 2026
.SYNOPSIS...
High pressure building along the Mid-Atlantic coast will briefly
wedge down the southeastern seaboard today, creating breezy east-
northeasterly winds this afternoon across the near shore waters.
Meanwhile, a trough moving westward towards the east central Florida
coast is expected to develop widely scattered showers and possibly a
few thunderstorms over the northeast Florida waters today. This
trough will move westward, dissipating over central Florida
tonight, with a few showers possibly lingering over the northeast
Florida waters. Otherwise, highs pressure will weaken as it pushes
southeastward towards Bermuda tonight and Wednesday, maintaining
a prevailing southeasterly flow across our local waters through
Thursday. Evening wind surges will increase speeds to near Caution
levels during the evening hours from Wednesday through the
weekend. Troughing will then develop over the southeastern
states this weekend, creating a prevailing southerly wind flow
that will gradually increase moisture levels, allowing scattered
afternoon and evening showers and thunderstorms to develop across
our local waters.
