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.
1881 Minnesota tornado outbreak
The 1881 Minnesota tornado outbreak was a deadly tornado outbreak that struck southern Minnesota on July 15–16, 1881. At least six tornadoes touched down between 2:00 pm – 6:00 pm CST, killing 24 people and injuring at least 123. The deadliest tornado of the outbreak, an F4 that killed 20 people in and near New Ulm, was likely a tornado family that may have caused F5 damage to rural farmsteads. Six people died in New Ulm, where people from nearby settlements had congregated to avoid Native American attacks.
