Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm
738 PM EDT Thu Apr 24 2025

SYNOPSIS

High pressure centered off the New England coast will continue to extend its axis southwestward across our local waters through Saturday night. Meanwhile, a cold front will move across the southeastern states on Saturday afternoon and evening. This front may bring scattered showers and thunderstorms to our local waters from Sunday through Monday. Strong high pressure building over the Great Lakes states in the wake of this front during the weekend will shift towards the southeastern seaboard early next week, with winds shifting to northeasterly and strengthening across our local waters from Sunday afternoon through Monday as the front pushes south of our local waters. Onshore winds will result in gradually building seas on Sunday night and Monday. This high pressure center will shift offshore on Monday night and Tuesday, allowing southeasterly winds to gradually diminish.
