The super outbreak of tornadoes that occurred in April 2011 is one of the deadliest in the United States in 40 years. The outbreak presents several tornado tracks in multiple counties to be investigated and ultimately analytically compared. The public's perceptions of and reactions to forecast warnings issued may be an overlooked factor. Are traditional forecast warnings too contextually limited to convey the differences in severity and confidence in the severity of storms? The investigation includes an analysis of: fatality demographics, track intensity rating (EF scale), and community impact compared to population density. Additionally, the weather forecasts and local communications between counties are analyzed and compared.
