As things heat up this summer, towns across the U.S. may see the sky above darken, and clouds shift into ominous looking spirals. In counties across the Midwest, tornado season is upon us. Recently, WeatherDB, a weather data site that's part of Graphiq, discovered which counties in the U.S. suffered the most damage from tornadoes in the last twenty years, but which counties experience the most tornadoes?
WeatherDB found out which 10 U.S. counties experienced the most tornadoes between 1951 and 2015. Data was collected from NOAA's Severe Weather Data Inventory. Counties are ranked by their Tornado Frequency, which is measured in tornadoes per year per 1,000 square miles. It is the average number of tornadoes that would hit the county per year, if the county was exactly 1,000 square miles. The area of the county was taken into account so larger counties were not weighted higher than smaller counties. Damage, death and injury numbers were gathered for each county. The total damage for each tornado was adjusted for inflation to today's dollars, and ties were broken using total adjusted damages.
To many, the South is synonymous with hurricanes. However, tornadoes are another natural hazard that southern states like Louisiana, Alabama and Florida experience annually. In fact, six separate counties in the South made it on this list. Texas is also home to multiple tornado-damaged counties. Tornadoes damage many areas in the U.S. we may not expect.
#10. Johnson County, Texas
Tornado Frequency: 2.29 per year Most Tornadoes in a Year: 17 (in 1988) Total Adjusted Damages: $81.4 million Total Deaths: 0 Total Injuries: 43

As Gallup noted in its assessment of the numbers "Utah's No. 1 position on the list is a direct result of that state's 59% Mormon population, as Mormons have the highest religious service attendance of any major religious group in the U.S."
