Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
232 AM EDT Mon May 4 2026
.SYNOPSIS...
High pressure centered over the southeastern states will shift
offshore this afternoon as weak low pressure situated along a
stationary frontal boundary moves eastward and away from Bahamas.
Breezy east to southeasterly winds are expected during the afternoon
and evening hours today and again on Tuesday. Caution level speeds
will be possible on Wednesday afternoon and evening, well in advance
of a cold front that will be entering the southeastern states. Winds
will shift to southerly on Wednesday night and then southwesterly on
Thursday as the frontal boundary slowly approaches our local waters
from the northwest. 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 on Thursday
night, followed by winds shifting to northerly on Friday morning and
then northeasterly 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.
