Why was the 2011 tornado season in the U.S. so extreme, and, with advanced warning systems, why did so many die? This program premiered on April 11, 2012 on PBS.
In 2011, the worst tornado season in decades left a trail of destruction across the U.S., killing more than 550 people. Why was there such an extreme outbreak? How do such outbreaks form? With modern warning systems, why did so many die? Is our weather getting more extreme - and if so how bad will it get? In this NOVA special, meet scientists striving to understand the forces at work behind last year's outbreak. Could their work improve tornado prediction in the future? NOVA also meets people whose lives have been upended by these extreme weather events and learn how we all can protect ourselves and our communities for the future.
