AMZ400-010630- Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm- 201 PM EDT Tue Apr 30 2024 .SYNOPSIS... High pressure centered off east coast will shift eastward rest of today as a weakening frontal boundary enters the southeastern states. South to southeast winds prevail this morning with a coastal surge in the afternoon as the Atlantic sea breeze shifts inland. Isolated showers and thunderstorms may develop over our local waters today into 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...
