| Episode Narrative | The broad upper low continued to drift very slowly east-northeast from east Texas during this period. Showers and thunderstorms became more numerous and very efficient rain producers across west and north Georgia. Tropical moisture continued to spread northward into the region. Precipitable water values increased to over two inches. The repeated rainfall across the same areas primed the stage for the record, historical, and catastrophic flood event that unfolded from the 21st into the 22nd. On the 19th, the bulk of the flood and flash flooding was confined to the western and northern suburbs of Atlanta, especially early on the 19th, when a good 6-hour period of heavy showers and thunderstorms trained across south Fulton, Cobb, Cherokee, Forsyth, DeKalb, and Gwinnett counties, dumping five to seven inches of rain in these areas. |
| Event Narrative | Clayton county Emergency Management personnel reported that general flooding continued across a small portion of far northern Clayton county as late morning and early afternoon flash flooding subsided. Additional minor property damage was observed. |
