AMZ400-300615- Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm- 152 PM EDT Mon Apr 29 2024 .SYNOPSIS... High pressure centered off the Carolina coast will weaken and shift eastward tonight and Tuesday as a weakening frontal boundary enters the southeastern states. Breezy southeast winds and elevated seas will prevail through tonight before prevailing winds shift to southerly by Tuesday morning. Isolated showers and thunderstorms may develop over our local waters on Tuesday and Wednesday as the dissipating frontal boundary moves over our area. Another high pressure center will then build over coastal New England late this week, resulting in onshore winds redeveloping over our local waters. A cold front is then expected to enter the southeast states by Saturday night and Sunday, possibly bringing a chance of showers and thunderstorms to our region by late in the upcoming weekend. .GULF STREAM...
