Tornadoes are nature’s most violent storms. Spawned from powerful thunderstorms, tornadoes can be extremely dangerous. Some tornadoes are clearly visible, while rain or nearby low-hanging clouds obscure others. Tornadoes develop extremely rapidly, and may dissipate just a quickly. Most tornadoes are on the ground for less than 15 minutes.

The wind may die down and the air may become very still. 

A cloud of debris can mark the location of a tornado even if a funnel is not visible. 

Tornadoes generally occur near the trailing edge of a thunderstorm. 

It is not uncommon to see clear, sunlit skies behind a tornado.
