"In the eye of the tornado, there's no more high and low"
What is a Tornado?
A tornado is a violently rotating column of air which descends from a thunderstorm to the ground. No other weather phenomenon can match the destructive power of tornadoes. Tornadoes can be strong enough to destroy large buildings, leaving only the bare concrete foundation. They can appear in the blink of an eye, and they can lift 30-ton railroad cars from their tracks and even drive straw, blades of grass, or pebbles into trees and telephone poles. This is what makes them so deadly.
Tornado paths can range from 100 yards to 2.6 miles wide and are rarely more than 15-20 miles long. They can last from several seconds to more than an hour, however, most don't exceed the 15 minute mark. Most tornadoes travel from the southwest to northeast with an average speed of 35 mph, but the speed of tornados has been observed to range from almost no motion to even speeds of excess of 70 mph.
