Tornado Alley
States such as Missouri, Iowa, Minnesota, Wisconsin, Illinois, Indiana, and western Ohio are sometimes included in Tornado Alley. Research suggests that tornadoes are becoming more frequent in the northern parts of Tornado Alley where it reaches the Canadian prairies.
Indiana
In a 2012 report, Indiana was ranked eighth in a list of the top 20 tornado-prone states based on National Weather Service data from 1950 through 2011. A 2011 report ranked South Bend 15th among the top 20 tornado-prone cities in the United States, while another report from 2011 ranked Indianapolis eighth. Despite its vulnerability, Indiana is not a part of tornado alley.
