A tornado is a violently rotating column of air extending from a thunderstorm to the ground. Tornadoes in the US occur most frequently in spring and summer.
The strongest tornadoes have rotating winds of more than 250 mph. Damage can include roof removal or complete destruction of buildings, uprooted trees, and can be life-threatening as a result.
