Tornadoes are one of nature's most violent storms.
Tornadoes come in all shapes and sizes and can occur anywhere in the United States and at any time of year. Tornadoes are always born out of severe thunderstorms. They can be stationary or travel at speeds up to 70 mph. When they are moving, they generally tend to travel from southwest to northeast and could be on the ground for over an hour traveling many miles.
