Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
224 AM EDT Tue May 5 2026
.SYNOPSIS...
High pressure ridge will continue to shift eastward early this week
while a cold front approaches from the northwest. Caution level
speeds will be possible on Wednesday afternoon and evening, well in
advance of the cold front that will be entering the southeastern
states. Showers and thunderstorms will likely accompany this frontal
passage on Thursday afternoon and evening, with strong storms
possible across the Georgia waters. Breezy northwesterly winds are
expected in the wake of this frontal passage late Thursday night,
followed by winds shifting to north on Friday morning and then
northeast by Friday afternoon as the frontal boundary likely stalls
over the Florida peninsula. Additional rounds of showers and
thunderstorms will be possible from Friday through the upcoming
weekend as a wave of low pressure develops along the stalled frontal
boundary that should be positioned near the northeast Florida
waters.
