An average of 1,224 tornadoes touch down per year across the United States. The top 10 states for tornadoes as of the most recent (1991-2015) average are as follows, in order from high to low: Texas, Kansas, Oklahoma, Florida, Nebraska, Illinois, Colorado, Iowa, Alabama, Missouri, and Mississippi.
Why is this part of Oklahoma so vulnerable to killer tornadoes? The short explanation is that Moore sits at the heart of Tornado Alley. Tornado Alley extends from the Rocky Mountains in the West to the Appalachians in the East. Seventy-five percent of the world's tornadoes hit in the U.S. That's more than 1,000 per year. (Canada, at No. 2, has just 100 per year.) And nowhere are they more common than in the swath of the nation's midsection centered around Texas, Oklahoma, Kansas, and the states to the north.
