How many tornadoes has Greene County had?
NOAA records 11 tornadoes in Greene County from 1955 to 2011, the strongest rated EF3, with 8 deaths and 109 injuries recorded in the county. A tornado that crossed a county line is counted in each county it touched, with the length of its path inside the county.
