Tornado Alley is a colloquial term for the area of the United States where tornadoes are most frequent. Although an official location is not defined, the areas in between the Rocky Mountains and Appalachian Mountains are the areas usually associated with it. Tornadoes are most common here because it is the region where warm, moist air from the Gulf of Mexico meets cold, dry air from the Rocky Mountains and Canada, creating intense, tornado-producing thunderstorms known as supercells.
