AMZ400-200930- Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm- 343 PM EDT Wed Jun 19 2024 .SYNOPSIS... Strong high pressure centered off the New England coast will maintain strong onshore winds and Small Craft Advisory level seas through Thursday night near shore and through Friday offshore. Coastal troughing that is situated over our local waters will continue to generate occasional fast moving showers and isolated thunderstorms through Thursday evening. Meanwhile, a trough that is generating disorganized thunderstorm activity to the east of the Bahamas will be steered westward, with this feature approaching our local waters after midnight on Thursday night. Showers and thunderstorms will briefly increase in coverage as this trough moves across our region through Friday. High pressure will then weaken while shifting further eastward over the Atlantic this weekend, allowing for diminishing winds and seas. Prevailing southerly winds are expected by early next week, with scattered to numerous thunderstorms remaining possible as another trough settles over the southeastern states. .GULF STREAM...
