AMZ400-150945- Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm- 211 PM EDT Sat Sep 14 2024 .SYNOPSIS... High pressure centered off the New England coast will be reinforced by a stronger high pressure center on Sunday, with this feature wedging down the southeastern seaboard through early portions of the upcoming week. Meanwhile, low pressure will develop over the Gulf Stream waters adjacent to the southeastern seaboard on Sunday, with this system potentially acquiring tropical characteristics early in the upcoming week as it moves northwestward towards the Carolina coast. Otherwise, a stationary frontal boundary will remain situated just south of our local waters through midweek, bringing episodes of showers and thunderstorms. Strengthening northeasterly winds and building seas will bring Small Craft Advisory conditions to the Southeast Georgia waters this afternoon. Small Craft Advisory conditions will then overspread the rest of our local waters on Sunday and Sunday night as northeasterly winds continue to strengthen and seas build. Winds and seas will then gradually diminish towards midweek as low pressure pivots northward across the coastal Carolinas and moves towards the Mid-Atlantic states. .GULF STREAM...
