Hurricanes and Tornadoes both contain strong rotating winds that can cause damage. A tornado is a spinning column of air that extends from the bottom of a cloud. Hurricanes form over warm water. They can be up to several hundred miles wide as well. Tornadoes are usually no higher than half a mile wide. A tornadoes wind can be way more dangerous than a Hurricanes wind.
