| Area Forecast Discussion National Weather Service Key West FL 1044pm EDT Sunday September 15 2024 Marine Issued at 1044pm EDT Sunday September 15 2024 There are no watches, warnings, or advisories in effect for the Florida Keys coastal waters. Light and generally variable breezes will continue through Friday over the Florida Keys coastal waters. A developing low pressure system off the Carolina coast will generate a higher northerly swell off the Upper Keys for Tuesday and Wednesday. The low will deepen into an upper level trough and slowly slide south towards the Florida Peninsula by Friday. Unpredictability in the movement of this trough means confidence in the extended forecast is very low. Climate On this day in 2023, the daily record high temperature of 94F was recorded in both Key West and Marathon. Temperature records date back to 1872 in Key West and 1950 in Marathon. NOAA Key West FL Office: Watches - Warnings - Advisories FL...None. GM...None. |
