Tornado

A tornado is a natural phenomenon that usually spawns from a supercell thunderstorm. A tornado also may spawn from a funnel cloud. At first, tornado expert Theodore Fujita invented the Fujita scale to measure from F0,F1,F2,F3,F4 and F5 tornadoes, as well as an F6. An F6 is the most dangerous tornado, as the wind speed is from 318 MPH to 500 MPH. Nobody has survived a F6 tornado.
