Severe thunderstorms spawned tornadoes and generated flooding rainfall over the Southeast on Monday evening. At least twelve tornadoes were reported with twisters spotted in Mississippi, Alabama and Georgia. Four deaths in Alabama and one in Florida have been blamed on this violent weather.

Total rainfall was measured from December 30, 2016 through early January 3, 2017 using precipitation estimates from NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG) data. IMERG data are produced using data from the satellites in the GPM Constellation, and is calibrated with measurements from the GPM Core Observatory as well as rain gauge networks around the world. This analysis of rainfall over the Southeast indicates that more than 12 inches (305 mm) of rain fell over the southeastern United States during this stormy period.
