10 Worst Tornado States

For the community of Moore, Oklahoma, tornadoes are a nearly annual occurrence. Since 1950, Cleveland County has experienced 67 tornadoes, including the record-breaking twister of 1999. But it’s not just the suburban enclave of Moore that’s favored by twisters—according to national weather data analyzed by The Daily Beast, Oklahoma is the most tornado-prone state in the country.

 

Using data compiled by NOAA’s National Weather Service severe weather database files, which includes tornado reports from 1950 through the end of 2012, we calculated which states have the highest tornado incidence rates. As we did two years ago, we ranked the states based on the number of tornadoes per square mile and the average severity of tornadoes using the Fujita scale. (The tornado per square mile was weighted twice the severity level.)
