AMZ400-210945- Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm- 914 PM EDT Thu Jun 20 2024 .SYNOPSIS... Weak low pressure situated about 300 miles to the east-southeast of Mayport, Florida late on Thursday evening may organize into a Tropical Depression overnight or early on Friday as it progresses west-northwestward across the Gulf Stream waters, with this feature approaching the northeast Florida coast late on Friday morning or during the early afternoon hours. Bands of gusty showers and embedded thunderstorms will increase in frequency and intensity during the overnight and predawn hours on Friday, with this activity continuing through late Friday afternoon before diminishing in coverage as this weak low pressure center progresses inland. Meanwhile, strong high pressure centered north of Bermuda will gradually weaken as it settles southward this weekend. Small Craft Advisory conditions will continue throughout our local waters tonight and Friday, followed by winds and seas diminishing to Caution levels on Friday night and then below Caution criteria on Saturday. Rounds of showers and thunderstorms will continue to develop over our local waters this weekend and into next week as prevailing winds become southerly ahead of a weakening surface trough that will settle over the southeastern states through midweek. .GULF STREAM...
