Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
314 AM EST Wed Nov 12 2025
.SYNOPSIS...
Arctic high pressure settling over our region early this morning
will continue to gradually weaken while shifting slowly southward
over the Florida peninsula tonight. Westerly winds will gradually
strengthen this afternoon and evening, followed by winds shifting
to northwesterly and increasing to Caution levels offshore after
midnight as another high pressure center builds southeastward from
the Upper Midwest towards the Tennessee Valley. This high pressure
center will push a weakening, dry frontal boundary southward
towards our local waters on Thursday night. Weakening high
pressure will then shift directly over our area on Friday and
Saturday as this frontal boundary dissipates. High pressure will
then shift south of our local waters on Saturday night and Sunday,
with west-southwesterly winds expected to gradually strengthen
ahead of another weakening, dry frontal boundary that will
approach the Georgia waters on Sunday night.
