About this data
Tornado records come from the NOAA Storm Prediction Center database of confirmed tornadoes, 1950–2025. Tornadoes that crossed state lines are counted in the state where they began. Counts in the early decades are lower partly because many weak tornadoes went unreported before Doppler radar and storm spotter networks.
