It is not known. About 1,800 tornadoes are recorded worldwide in an average year, most of them in the U.S. but the actual number of tornadoes is probably several times higher. It is likely that thousands of tornadoes occurring in poor countries or remote areas are never recorded.
Since official record began in 1950, California has had 404 recorded tornadoes up through the year 2013. The actual number of tornadoes is likely much higher, as many of the less intense tornadoes went without being recorded.
There were 26 recorded tornadoes in North Carolina in 2010.
Since official records began in 1950 the U.S. has recorded approximately 61,000 tornadoes. Records prior to that are more difficult to track down. Similarly, records for other countries are incomplete.
Kansas, Oklahoma, and Texas share in this distinction. More states probably qualify, as during this time period, most F0 and F1 intensity tornadoes were not recorded.
That would be Texas, with 4,949 recorded tornadoes.
Texas has the highest number of recorded tornadoes, at over 7,700 since official records began in 1950.
There were 866 recorded tornadoes in the U.S. in 1980. 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.
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 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.
There were 919 recorded tornadoes in the U.S. in 1975. 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.
