The area most at risk for tornadoes

"Tornado Alley" is a region with the most common tornadoes, just east of the Rockies. The city with the most recorded tornadoes is Oklahoma City, Oklahoma, which also had the strongest winds ever measured, over over 316 MPH, during the tornado of May 3, 1999. That tornado also holds the record for the most costly damage - over one billion dollars! But because of good weather forecasting, only 36 people were killed.
