 Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
 336 AM EST Sun Dec 14 2025
 
 
 .SYNOPSIS...
 
 An Arctic cold front will cross the Georgia waters towards noon
 today and will continue southward across the northeast Florida
 waters during the early to mid afternoon hours. Winds will shift to
 northwesterly and will steadily increase this afternoon through
 tonight. Small Craft Advisory conditions will develop early this
 afternoon across the Georgia waters, followed by winds shifting to
 northerly towards sunset and then northeasterly after midnight.
 Frequent Gale force wind gusts will develop late this afternoon and
 will continue through around sunrise on Monday throughout our local
 waters as strong high pressure wedges down the southeastern
 seaboard. Coastal troughing will then develop over our local waters
 on Monday and Monday night, developing scattered showers, mainly
 offshore. Weakening high pressure will then shift southward towards
 our area on Tuesday, allowing winds and seas to quickly subside.
 High pressure will then shift offshore on Wednesday afternoon, with
 scattered showers possible by Thursday and Thursday night in advance
 of a weakening frontal boundary that will be entering the
 southeastern states. This front will likely cross the Georgia waters
 on Friday morning and may then stall over the northeast Florida
 waters by Friday night.
