Tornado Alley

Tornado Alley is a colloquial term for the area of the United States where tornadoes are most frequent.
==Tornado Geography==
No state is entirely free of tornadoes, but they occur more frequently in the Central United States, between the Rocky Mountains and Appalachian Mountains. According to the storm events database of the National Climatic Data Center, Texas reports more tornadoes than any other state, though the very large land area should be taken into account. Kansas and Oklahoma rank first and second respectively in the number of tornadoes per square mile. Florida also reports a high number and density of tornado occurrences, though tornadoes there rarely approach the strength of those that sometimes occur in the southern plains. Regionally, the frequency of tornadoes in the United States is closely tied with the progression of the warm season when warm and cold air masses often clash.
