Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1229 PM EST Sun Dec 14 2025
.SYNOPSIS...
Winds will continue to increase across the local waters as an arctic
cold front moves through this afternoon. Winds will gradually
increase through the evening with strong, frequent gusts to Gale
Force developing toward sunset, especially across the northeastern
Florida coastal waters. Those winds will quickly increase seas
tonight as well, with rough waves as high as 10 feet offshore and
across the NE FL coastal waters. As winds turn northeasterly Monday,
coastal troughing will develop encouraging scattered showers, mainly
offshore. Weakening high pressure will then shift southward Tuesday,
allowing winds and seas to subside. High pressure then shifts
offshore on Wednesday afternoon in advance of a weakening frontal
boundary that will likely cross the Georgia waters on Friday morning
and may then stall over the northeast Florida waters by Friday
night.
