A tornado is defined as "a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system." Tornadoes can vary from just 50 yards to 1 mile in width. Most tornadoes in the US are small and weak (EF-0 or EF-1), but rare EF-5 tornadoes pack winds in excess of 200 mph!
