Severe Weather Season, Restated for Columbus
As covered in full on the flood-hurricane-risk topic page, Columbus's practical severe-weather risk is tornado and severe-thunderstorm season, concentrated March through June, plus real freshwater flood risk specifically tied to the Chattahoochee River -- a structurally different seasonal risk calendar from a hurricane-season-driven Gulf Coast or coastal Georgia market.
Rainfall
Columbus receives roughly 51 inches of precipitation annually -- slightly more than Athens's roughly 49 inches -- consistent with the broader humid subtropical Southeast, with the Chattahoochee River's flow directly shaped by that regional rainfall pattern alongside dam-controlled releases that also power the whitewater course detailed in the base record.
