Information about tornadoes
Tornadoes are the most powerful, unpredictable and destructive weather systems on earth. In an average year, 1000 tornadoes are reported nationwide. The worst tornadoes are capable of very destructive wind speeds of up to 300 mph (miles per hour). Tornadoes can damage paths of up to one mile wide to 50 miles long.
When a tornado forms cool and dry air combine together, the cool air drops down and the warm air rises. The warm air eventually twists into a spiral and forms a funnel shaped cloud. A tornado is usually formed after/while a storm is occurring.

Some people that live in commonly affected tornado areas have an underground cellar which they stay in during the tornado. Local communities are notified by the local weather advise warning system.
