3 What are Tornadoes A tornado is a narrow, violently rotating column of air that extends from the base of a thunderstorm to the ground. Because wind is invisible, you can't always see a tornado. A visible sign of the tornado, a condensation funnel made up of water droplets, sometimes forms and may or may not touch the ground during the tornado lifecycle. Dust and debris in the rotating column also make a tornado visible and confirm its presence.

5 How Fast are the Winds in a Tornado
Most tornadoes have winds in the range of about mph. The most damaging tornadoes usually have winds over 165 mph. On rare occasions winds can exceed 300 mph. A tornado spins counterclockwise. They are very small, intense low pressure areas. Lowest pressure recorded 850mb. The pressure difference between the inside and outside of a tornado is the most extreme in all of nature.

10 Safety Precautions 1. Seek shelter under a sturdy table in the basement. 2. If no basement is available, go to a first floor, small interior room or a room on the opposite side from a tornado. Stay away from windows. 3. In schools, churches, and shopping centers, go to designated shelters away from outside walls, glass, and large rooms (malls, auditoriums). Get under a table or counter or in a restroom or small storeroom. DO NOT GO TO YOUR PARKED CAR 4. In motels, lie down in the lowest-level interior hallway away from glass. Dive under a bed or pull a mattress on top of you as last resort. 5. In a vehicle, drive away at a right angle to the storm movement. DO NOT GET CAUGHT IN YOUR VEHICLE. Abandon your vehicle and lie in a ditch or culvert or under a low bridge. Overall: Underground and under a table are the watchwords. People who get under something usually survive.
