| Area Forecast Discussion National Weather Service Key West FL 1101am EDT Tuesday September 23 2025 Marine Issued at 1038am EDT Tuesday September 23 2025 There are no watches, warnings, or advisories in effect for the Florida Keys coastal waters. However, a Coast Flood Statement in effect for the Upper Keys means that mariners should be prepared for less clearance underneath fixed bridges. From synopsis, rain and thunder chances will remain elevated through the rest of today as a moisture surge and low-level trough continue to push through the Florida Keys marine zones. High pressure pushing off the Eastern Seaboard will support light to gentle breezes through the rest of the work week, along with a return to near normal rain chances for tonight through Saturday. Climate On this day in Keys Weather History in 2023, the daily record rainfall of 1.93" was recorded in Marathon. Rainfall data for Marathon dates back to 1950.
