Atlanta receives around 1,270 mm (about 50 inches) of rain a year, among the wetter major U.S. cities, fairly evenly spread across the seasons with both winter frontal systems and summer convective thunderstorms contributing substantially. The city’s hilly terrain and rapid urban growth have significantly increased impervious surface area, meaning intense summer downpours now produce faster and more severe flash flooding on major roads and creeks than the same rainfall would have a generation ago. Remnants of Gulf Coast hurricanes occasionally track through the region too, adding heavy rain well inland. Because both fast local storms and occasional tropical remnants matter here, radar is a genuinely practical everyday tool. NWS Doppler radar KFFC (Atlanta/Peachtree City) covers the region.
