Michigan may not be known for its tornadoes, but there have been some significant twisters that have touched down in the Great Lake State, dating back to the 1950s. Michigan averages 17 tornadoes each year, but the annual occurrence has ranged from as high as 39 to as low as two.
Michigan Tornado Facts
Tornadoes are an infrequent visitor to Michigan. According to the National Climatic Data Center, the state averages just 17 tornadoes a year. While 17 may seem like a substantial number, compared to the twister-prone state of Texas, which averages 35 to 159 tornadoes per year, Michigan's yearly tornado count is relatively low.
Of the all the Michigan tornadoes recorded in history, only about 5 percent reach F4 or F5 on the Fujita Tornado Damage Scale. An F4 or F5 storm is categorized as “devastating” and the powerful winds reach speeds of 207 mph or more. According to the Extreme Weather Sourcebook of 2001, Michigan ranked 17th in the nation in terms of economic loss caused by tornadoes.
Michigan tornadoes tend to arise in the late afternoon and early evening, usually between the hours of 4 and 6 p.m. While they occur most often in the month of June, April and May also mark the height of tornado season, according to the National Weather Service. However, tornadoes have been reported all year, excepting the months of December and January.
