Tornadoes are violent rotating columns of air that extend from thunderstorms to the ground. They are most common in the US, especially in Oklahoma and the Midwest, due to collisions of warm and cool air masses. Tornadoes can cause extensive damage and occur suddenly, so it is important to monitor weather alerts and seek sturdy shelter immediately, such as a basement, storm cellar, or interior room, if a tornado warning is issued.
