 Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
 117 PM EST Sun Feb 15 2026
 
 
 .SYNOPSIS...
 
 A robust low pressure system moving across the southeastern US this
 afternoon will lose some of its steam as it moves toward the Mid
 Atlantic coast tonight where it will reintensify. The cold front
 associated with the system will send a squall line across the waters
 this afternoon and evening and may require Special Marine Warnings
 for both waterspouts and strong outflow winds. Outside of the
 influence from thunderstorms, strong southerly winds will lead to
 Small Craft Conditions and occasional Gale force gusts through the
 evening. Winds will gradually diminish overnight while turning
 northerly. High pressure building to the north behind the front will
 lead to breezy northeasterly winds through Monday afternoon. Winds
 relax through midweek as high pressure drifts farther northeastward
 across the central Atlantic.
