F5 Tornadoes

F5 Tornado in Canada

An F5 tornado is in category five of the Fujita scale, the deadliest ranking for a tornado. The wind speed range of this phenomena is 261-318 miles per hour. Tornadoes of this strength can lift well-constructed houses off their foundations, strip the bark off of trees, and fling objects over 300 ft. The most deadly tornado in the US was the Tri-State Tornado on march 18, 1925, in Missouri.
