Tornadoes Describe the path of a tornado.
A tornado is an extremely violent and destructive whirlwind. It extends down from a mass of dark clouds as a whirling funnel and moves over land in a narrow path. Most tornadoes also follow a northeast course at about 10 to 20 mph. A tornado is a column of winds that rotate at very high speeds. An average tornado will be 400 to 500 feet wide and travel four or five miles on the ground, lasting only a few minutes.
