For
those of you who don't live in the plains of
North America, a tornado is a swirling mass
of air, produced from thunder clouds, where
wind speeds may vary from 40 - 300 miles per
hour. However, tornadoes with speeds over 280
miles per hour are, fortunately, not common.
Tornado strength is rated on the Fujita
Scale with F0 being the weakest and F5 the strongest.
However, on a very rare occasion an F6 could
occur.
