Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
111 PM EDT Mon Jun 30 2025

.SYNOPSIS...

Atlantic high pressure will continue to extend its axis westward
across the Florida peninsula through midweek as a weak surface
trough settles over the southeastern states. This weather pattern
will create prevailing south to southwesterly winds, with evening
wind surges bringing speeds up to Caution levels over the offshore
waters. Showers and thunderstorms developing over land will progress
eastward across our local waters during the late afternoon and
evening hours today and Tuesday, with a few strong storms possible.
Stronger storms will be capable of producing briefly gusty winds,
frequent lightning strikes, and torrential downpours. A frontal
boundary will then sink over the southeastern states late this week,
stalling near our local waters by the weekend. Waves of showers and
thunderstorms will be possible later this week through the holiday
weekend. Please stay tuned to the latest National Hurricane Center
outlooks for any potential tropical low pressure development along
this stalling frontal boundary late this week and during the
upcoming weekend.
