Where do most tornadoes occur? Where is tornado alley?
The United States has the highest incidence of tornadoes worldwide, with around 1000 occurring every year. The country’s unique geography brings together polar air from Canada, tropical air from the Gulf of Mexico, and dry air from the Southwest to clash in the middle of the country, producing thunderstorms and the tornadoes they spawn. Tornadoes have hit all 50 U.S. States, but some states have tornadoes more often than others. Oklahoma, Texas, and Florida are the leading candidates. Frequent thunderstorms in western Florida contribute significantly to the number of tornadoes there, but the tornadoes tend to be relatively weak. Fewer thunderstorms occur in the central Great Plains, but tornadoes spawn there frequently because of the low-level wind shears in that part of the country.
