There were 201 recorded tornadoes in the U.S. in 1950. Note however that at this point in history the majority of weak tornadoes were missed, and most tornadoes are weak. The actual number of tornadoes was probably several times this figure.
There were 260 recorded tornadoes in the U.S. in 1951. Note however that at this point in history the majority of weak tornadoes were missed, and most tornadoes are weak. The actual number of tornadoes was probably several times this figure.
There were 240 recorded tornadoes in the U.S. in 1952. Note however that at this point in history the majority of weak tornadoes were missed, and most tornadoes are weak. The actual number of tornadoes was probably several times this figure.
There were 121 confirmed tornadoes in Texas in 1970. However the number of actual tornadoes was probably higher as a significant portion of weak tornadoes were missed at this time in history due to technological limitations.
There were 422 recorded tornadoes in the U.S. in 1953. Note however that at this point in history the majority of weak tornadoes were missed, and most tornadoes are weak. The actual number of tornadoes was probably more than twice this figure.
There were 987 recorded tornadoes in the U.S. in 1967. Note however that at this point in history the majority of weak tornadoes were missed and most tornadoes are weak. The actual number of tornadoes was probably much higher than this figure.
There were 856 recorded tornadoes in the U.S. in 1989. Note however that at this point in history a notable portion of weak tornadoes were missed and most tornadoes are weak. The actual number of tornadoes was probably higher than this figure.
There were 1133 recorded tornadoes in the U.S. in 1990. Note however that at this point in history a notable portion of weak tornadoes were missed and most tornadoes are weak. The actual number of tornadoes was probably higher than this figure.
There were 945 recorded tornadoes in the U.S. in 1974. Note however that at this point in history a significant portion of weak tornadoes were missed and most tornadoes are weak. The actual number of tornadoes was probably significantly higher than this figure.
