Area Forecast Discussion National Weather Service Key West FL 1052pm EDT Monday May 12 2025 Marine Issued at 1052pm EDT Monday May 12 2025 Deep troughing centered over the northern Gulf coast will lift northward overnight continuing to pump in abundant moisture through the forecast area. Moderate south to southwest breezes will veer more westerly while the heart of the parent low meanders along the northern Gulf. Scattered to numerous showers with embedded isolated to scattered thunderstorms will continue overnight into 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. Climate As of 10 PM, the Florida Keys Marathon International Airport recorded 1.45 inches of rainfall. This breaks the previous daily rainfall record of 0.94 inches, set in 1987. Additional rainfall is possible before midnight tonight. A follow-up record event will be issued with the morning climate to reflect the final daily total.
