| Area Forecast Discussion National Weather Service Key West FL 430am EDT Thu September 12 2024 Marine Issued at 430am EDT Thu September 12 2024 Elevated water levels continue to be observed at the Vaca Key and Blackwater Sound tide gauges, and water levels are now approaching statement levels at Key West as well. We expect these elevated water levels to continue through the next several days as we approach the full moon, and move into the time of year when we typically see long periods of above normal tides. A Coastal Flood Statement remains in effect for the Middle and Upper Keys, and we expect this will need to be eventually expanded to cover the Lower Keys as well. Late night observations show SSE breezes of 7 to 10 knots along the reef and at Long Key C-MAN, with seas at Satan Shoal running near 2 feet in long period SW swell. From the synopsis, gentle southeast breezes across the Keys coastal waters this morning will give way to light and variable breezes this afternoon through Monday. Weakening Tropical Storm Francine will continue moving inland across the Lower Mississippi Valley through Friday, with westerly swells from Francine continuing to impact the western Keys waters. Climate On this day in Keys weather history in 2020, the daily record rainfall of 9.37" was recorded. This high daily rainfall value was attributed to Tropical Storm Sally passing by to the north of the Keys earlier in the day and then Cuban thunderstorm outflow surging northward across the Straits of Florida that evening. During the late evening hours a thunderstorm over the Lower Keys produced 3.98" of rainfall at KEYW in 1 hour. The second highest hourly rainfall rate recorded by the EYW ASOS, behind November 11, 1980. This led to numerous reports of flooded streets and stalled cars in Key West, with flooding lasting several hours. Additionally, 11.36" of rainfall was recorded at the WFO. This is also the wettest day ever recorded during the month of September, toppling 1919's record of 7.47" on September 10th, by almost 2 whole inches.
