The highest accepted forward speed of an intense tornado on record was 75 mph (121 km/h) from the 1974 Guin tornado that tore across northwestern Alabama. Other weak tornadoes have approached or exceeded this speed, but this is the fastest forward movement observed in a major tornado. [16] The 1977 Birmingham tornado had an average forward ...
