Marine
Issued at 1105am EDT Monday May 12 2025 No watches, warnings, or advisories are in effect for the coastal waters of the Florida Keys. From synopsis, deep troughing over the Gulf is still in place with a plume of abundant moisture encompassing most of the forecast area. Moderate to occasionally fresh southeast to south breezes will veer southwesterly while the heart of the parent low meanders along the northern Gulf. Scattered to numerous showers with embedded isolated to scattered thunderstorms will continue through early Tuesday. As the low lifts toward the northeast during the middle of the week, higher pressure will be able to fill in behind it, encouraging drier weather and slackening breezes.
