Missouri
Located in Tornado Alley, Missouri also receives extreme weather in the form of severe thunderstorms and tornadoes. The most recent tornado in the state to cause damage and casualties was the 2011 Joplin tornado, which destroyed roughly one-third of the city of Joplin. The tornado caused an estimated $1–3 billion in damages, killed 159 (+1 non-tornadic), and injured over 1,000 people. It was the first EF5 to hit the state since 1957 and the deadliest in the U.S. since 1947, making it the seventh deadliest tornado in American history and 27th deadliest in the world. St. Louis and its suburbs also have a history of experiencing particularly severe tornadoes, the most recent memorable one being an EF4 tornado that damaged Lambert-St. Louis International Airport on April 22, 2011. One of the worst tornadoes in American history struck St. Louis on May 27, 1896, killing at least 255 and causing $10 mil. damage ($3.9 bil. damage in 2009) or $ in today's dollars.
History of the United States (2008–present)
In the spring of 2011, several major tornado outbreaks affected the Central and Southern United States. 43 people were killed in a tornado outbreak from April 14–16. Approximately 350+ people were killed in a tornado outbreak from April 25–28, the deadliest US tornado outbreak in 75 years (since the 1936 Tupelo-Gainesville tornado outbreak). States particularly hit hard by the outbreaks included Oklahoma, Arkansas, Mississippi, Tennessee, Georgia, North Carolina, Virginia, and most especially, Alabama, which sustained over 250 fatalities alone. The latter outbreak produced $10 billion in damage, making it the costliest tornado outbreak in history. On May 22, an EF5 tornado devastated Joplin, Missouri, killing 154, injuring over 1,000 people, and causing $1–3 billion in damage, making it the deadliest single US tornado in 64 years and the costliest single tornado of all time.
