Tropical Storm Debby lashed the U.S. Southeast in the first week of August 2024, dropping copious amounts of rain. The storm first came ashore as a Category 1 hurricane in Florida’s Big Bend region on August 5 and then weakened to a tropical storm as its center moved inland. Skirting the Atlantic coast, it added to rainfall totals in Florida, Georgia, and the Carolinas.
The map above shows rainfall accumulation over the five-day period ending at 7:59 p.m. Eastern Time (23:59 Universal Time) on August 7, 2024. These data are remotely sensed estimates that come from IMERG (the Integrated Multi-Satellite Retrievals for GPM), a product of the GPM (Global Precipitation Measurement) mission, and may differ from ground-based measurements. For instance, IMERG data are averaged across each pixel, meaning that rain-gauge measurements within a given pixel can be significantly higher or lower than the average.
During this five-day period, dozens of cities and towns across Florida, Georgia, and the Carolinas saw rainfall totals of more than a foot. In Florida, 17.78 inches (452 millimeters) fell in Sarasota and 19.67 inches (500 millimeters) fell in Lake City, according to the National Weather Service (NWS). In South Carolina, the town of Summerville saw 18.25 inches (464 millimeters).
