DEF

Formation of a large number of tornadoes, either in groups or as individuals, within a 24- to 48-hour period over a particular area.

CONT

A tornado family is a group of tornadoes spawned by a single thunderstorm. A "family" has had as many as 7 tornadoes, although two is much more common. The family gets a name based on the most damaging event. In 1991, a tornado passed over an underpass on the Kansas Turnpike, resulting in a famous video. That tornado was the fourth and last member of the Andover tornado family. The Andover tornado was the third tornado from that thunderstorm and it killed 17 people.

OBS

In recent years, Galway (1977) has defined ten or more tornadoes as constituting an outbreak.
