Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
234 AM EDT Wed May 13 2026
.SYNOPSIS...
Frontal boundary will be south of the waters today as a wave of low
pressure moves into the coastal east central FL waters. High
pressure ridge axis extendin from the Atlantic into the Carolinas
will weaken as the high departs east into the Atlantic. Winds from
the east today will decrease into the afternoon and turn more
northeasterly as the low moves east northeastward into early this
evening. Decreasing winds and seas will end small craft advisory
conditions nearshore early this morning and offshore by midday
with excercise caution conditions lingering until late afternoon
due to elevated seas. Numerous showers and isolated T'storms over
the waters will also diminish steadily through the afternoon
hours as the low exits to the east.
A dry cold front will approach the waters late tonight and exit
early Thursday morning with high pressure building in from the
northwest with breezy northwest winds nearing exercise caution
levels. The high will build to the north on Friday and then to the
east northeast this weekend with dry conditions and daily
seabreeze circulation increasing winds nearshore.
