  Also known as "twisters," they extend downward from the huge clouds of a severe thunderstorm. The winds that rotate within a tornado usually reach a speed of almost 300 miles per hour! A tornado often sweeps through an area quickly, but it can cause considerable destruction. There have been a number of remarkable reports of tornadoes. In one instance, a schoolhouse was demolished while the 85 students originally inside it were carried more than 400 feet with none killed. There was also a case of five railway coaches, each weighing 70 tons, lifted from their tracks.
