Tornadoes are more common in the United States than in any other country of the world and although the U.S. "tornado season", the period in which most tornadoes strike, is March through August violent tornadoes and major tornado outbreaks have been documented during every month of the year.
The Midwestern states are very prone to tornado activity, as it is part of "Tornado Alley", a colloquial term for the area of the United States where tornadoes are most frequent. States included in the area that are hit by tornadoes the most are Kansas, Missouri, Nebraska, Iowa, and South Dakota.
As spring passes and summer begins, the mass of warm moist air moves northwest into the Great Plains and Midwestern states. During the months of May and June, tornado activity is at its peak in the southern Great Plains. The air mass then moves northward into the Northern Great Plains and the Great Lakes area, causing a tornado activity peak in these areas during the summer months. During the late summer and early fall months, tornado activity in the United States tapers off.
The Southern United States has suffered more tornado fatalities than any other part of the country. Some areas experience repeated damaging tornado events, such as the Tennessee Valley in northern Alabama. The state of Alabama is tied for the most reported F5 tornadoes. For the period 1950 to 2006, 358 people were killed by tornadoes in Alabama, ranking the state third nationwide behind Texas (521) and neighboring Mississippi (404). Fourth is Arkansas (336) and fifth is Tennessee with 271 fatalities. (Tornadoes in the United States)
