Yes. When a single storm system produces multiple tornadoes in a relatively short time over an area it is called a tornado outbreak. There are usually several small outbreaks and one or two large outbreaks each year. Additionally, often within an outbreak, one thunderstorm can produce several tornadoes in succession. This is called a tornado family. Another phenomenon often mistaken for groups of tornadoes is a multivortex tornado. A multivortex tornado contains smaller, short lived vortices within the main circulation. In some cases this may look like several tornadoes moving in circles, but it is really one tornado.
