A devastating tornado tore through Moore, Oklahoma on Monday, killing at least 24 and leaving the city looking like “a debris field,” according to comments Mayor Glenn Lewis made to NBC.
The tornado was one of at least 22 tornadoes that struck across six states on Monday, a day after a northeast-moving storm spawned over 20 tornadoes through Texas, Minnesota, Kansas, Illinois, Iowa, Missouri, Nebraska and Oklahoma.
What Is a Tornado?
A tornado is a violently rotating column of air that extends from a thunderstorm and comes into contact with the ground, according to the National Oceanic and Atmospheric Administration (NOAA). In an average year, NOAA says about 1,000 tornadoes are reported nationwide.
