Tornado outbreak sequence of May 21–26, 2011
The tornado outbreak sequence of May 21–26, 2011 was one of the largest tornado outbreaks on record which affected the Midwestern and Southern regions of the United States. Most of the tornadoes developed in a corridor from Lake Superior southwest to central Texas; isolated tornadoes occurred in other areas. An especially destructive tornado destroyed one-third of Joplin, Missouri, resulting in 158 deaths and over 1,000 injuries. The Joplin tornado is the deadliest in the U.S. since April 9, 1947, when an intense tornado killed 181 in the Woodward, Oklahoma area. Tornado-related deaths also occurred in Arkansas, Kansas, Minnesota, and Oklahoma. Overall, the tornado outbreak resulted in 184 deaths, 6 of those non-tornadic, making it second only to the 2011 Super Outbreak as the deadliest since 1974, and the second costliest tornado outbreak in U.S. history behind that same April 2011 outbreak, with insured damage estimated at $4–7 billion.
Tornado outbreak sequence of May 7–15, 2008
The deadliest tornado and most notable tornado of the outbreak took place from a single supercell that tracked through Ottawa County, Oklahoma, Newton County, Missouri, and Barry County, Missouri, in the late afternoon of May 10. Twenty-one people were killed in the tornado – fatalities took place in Picher, Oklahoma (where six people were killed), and Newton and Barry counties in Missouri (where 15 people were killed). One other person was killed in Jasper County, Missouri from an EF1 tornado. Eight of the victims died inside their cars, troubling experts who say the inside of a vehicle is one of the worst places to be during a tornado. This was the second deadliest tornado of the year behind the EF3 tornado that affected areas northeast of Nashville, Tennessee, on February 5, 2008 and killed 22.
