Tornado warnings are short because tornadoes themselves usually do not last long, usually no more than a few minutes. (A tornado waring means that a tornado has either been detected or may be imminent.) Even when tornadoes do last a long time they usually don't stay in the same place for long. Because of this, the tornado threat from a thunderstorm in any given place will usually not last more than twenty minutes. If the threat persists then a warning may be renwed.
