Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
745 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 to 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, high 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.
