The air column rotates violently, and in the most severe tornados can reach speeds in excess of 300 miles per hour or more.
Whether you live in an area that gets hurricanes or tornados or simply need to be ready for the occasional storm, an emergency kit can be an essential part of your household supplies.
The most violent tornados are capable of tremendous destruction with wind speeds of 250 mph or more.
Some tornados leave a path of destruction and damage that can measure more than 50 miles long and one mile wide.
When a tornado watch turns into a tornado warning it means that one or more tornados have actually been sighted or are indicted in the area by a weather tracking radar system.
