This article lists various tornado records. The most "extreme" tornado in recorded history was the Tri-State tornado, which spread through parts of Missouri, Illinois, and Indiana on March 18, 1925. It is considered an F5 on the Fujita Scale, holds records for longest path length at 219 miles (352 km) and longest duration at about 3+1⁄2 hours. The 1974 Guin tornado had the highest forward speed ever recorded in a violent tornado, at 75 mph (121 km/h). The deadliest tornado in world history was the Daulatpur–Saturia tornado in Bangladesh on April 26, 1989, which killed approximately 1,300 people. In the history of Bangladesh, at least 19 tornadoes killed more than 100 people each, almost half of the total for the world. The most extensive tornado outbreak on record was the 2011 Super Outbreak, which resulted in 367 tornadoes and 324 tornadic fatalities, whereas the 1974 Super Outbreak was the most intense tornado outbreak on tornado expert Thomas P. Grazulis's outbreak intensity score with 578, as opposed to the 2011 outbreak's 378.
The 1905 Snyder, Oklahoma, tornado was a powerful tornado that struck the town of Snyder, Oklahoma, in Kiowa County on Wednesday, May 10, 1905. The event was one of the worst natural disasters ever to hit the state of Oklahoma. The tornado killed 97 people, making it the second most deadly tornado in Oklahoma history. The tornado was part of a larger, multiple-day tornado outbreak that hit several states across the Midwestern United States, including Kansas, Oklahoma, and Missouri.
In mid-May of 1968, a significant and deadly tornado outbreak struck most of the central and southern United States. Producing 46 tornadoes, the outbreak killed at least 72 people, including 45 in Arkansas alone. The outbreak also produced two F5 tornadoes in Iowa. It was one of the deadliest tornado outbreaks in the United States since the 1960s and is one of the deadliest outbreaks in Iowa history.
From Sunday to Monday, February 21–22, 1971, a devastating tornado outbreak, colloquially known as the Mississippi Delta outbreak, struck portions of the Lower Mississippi and Ohio River valleys in the Southern and Midwestern United States. The outbreak generated strong tornadoes from Texas to Ohio and North Carolina. The two-day severe weather episode produced at least 19 tornadoes, and probably several more, mostly brief events in rural areas; killed 123 people across three states; and wrecked entire communities in Mississippi. The strongest tornado of the outbreak was an F5 that developed in Louisiana and crossed into Mississippi, killing 48 people, while the deadliest was an F4 that tracked across Mississippi and entered Tennessee, causing 58 fatalities in the former state. The former tornado remains the only F5 on record in Louisiana, while the latter is the deadliest on record in Mississippi since 1950. A deadly F4 also affected other parts of Mississippi, causing 13 more deaths. Other deadly tornadoes included a pair of F3s—one each in Mississippi and North Carolina, respectively—that collectively killed five people.
A long-lived tornado outbreak sequence affected the Southern Plains, the southeastern and Middle Atlantic region of the United States from May 7–11, 2008. The storm produced 120 confirmed tornadoes starting on May 7 and lasting until late on May 11. The outbreak sequence killed 28 people across several states; 25 were killed by tornadoes. The event occurred less than a week after a deadly tornado outbreak that principally affected the state of Arkansas and killed 7 people.
A multi-day tornado outbreak affected the central plains of the United States from May 22–27, 2008. It was also one of the largest continuous tornado outbreaks on record. A total of 173 tornadoes were confirmed, with the most intense activity occurring across the Great Plains. One person was killed when a large wedge tornado struck Windsor, Colorado, and two more deaths were reported in Pratt County, Kansas. One person was also killed near Hugo, Minnesota on May 25 and nine were killed by an EF5 tornado that destroyed most of Parkersburg, Iowa and a small subdivision of New Hartford, Iowa. Another fatality, caused by lightning related to the storms, occurred in central Kansas.
Tornadoes are more common in the United States than in any other country or state. The United States receives more than 1,200 tornadoes annually—four times the amount seen in Europe. Violent tornadoes—those rated EF4 or EF5 on the Enhanced Fujita Scale—occur more often in the United States than in any other country.
This page documents the tornadoes and tornado outbreaks of 1997, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes, however by the 1990s tornado statistics were coming closer to the numbers we see today.
This page documents the tornadoes and tornado outbreaks of 1998, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes, however by the 1990s tornado statistics were coming closer to the numbers we see today.
The 1999 Bridge Creek–Moore tornado was a large, long-lived and exceptionally powerful F5 tornado in which the highest wind speed ever measured globally was recorded at 321 miles per hour (517 km/h) by a Doppler on Wheels (DOW) radar. Considered the strongest tornado ever recorded to have affected the Oklahoma City metropolitan area, the tornado devastated southern portions of Oklahoma City, Oklahoma, United States while near peak intensity, along with surrounding suburbs and towns to the south and southwest of the city during the early evening of Monday, May 3, 1999. Parts of Bridge Creek were rendered unrecognizable. The tornado covered 38 miles (61 km) during its 85-minute existence, destroying thousands of homes, killing 36 people, and leaving US$1 billion in damage, ranking it as the fifth-costliest on record not accounting for inflation. Its severity prompted the first-ever use of the tornado emergency statement by the National Weather Service.
From May 21 to May 26, 2011, one of the largest tornado outbreaks on record affected the Midwestern and Southern regions of the United States. A six-day tornado outbreak sequence, most of the tornadoes developed in a corridor from Lake Superior southwest to central Texas, while isolated tornadoes occurred in other areas. An especially destructive EF5 tornado destroyed one-third of Joplin, Missouri, resulting in 158 deaths and over 1,000 injuries. The Joplin tornado was the deadliest in the United States 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 186 deaths, 8 of those non-tornadic, making it second only to the 2011 Super Outbreak as the deadliest since 1974. It was the second costliest tornado outbreak in United States history behind that same April 2011 outbreak, with insured damage estimated at $4–7 billion.
In the afternoon hours of April 27, 2011, a large, long-lived, and devastating EF5 tornado impacted several towns in rural northern Alabama before tearing through the northern suburbs of Huntsville. It was the deadliest tornado of the 2011 Super Outbreak, the largest tornado outbreak in United States history. The second of four EF5 tornadoes to touch down on April 27, along with the Philadelphia, MS, Smithville, MS, and Rainsville, AL tornadoes; the tornado reached a maximum width of 1.25 miles (2.01 km) and was estimated to have had peak winds of 210 mph (340 km/h).
This page documents the tornadoes and tornado outbreaks of 1974, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes.
This page documents notable tornadoes and tornado outbreaks worldwide in 1973, but mostly features events in the United States. According to tornado researcher Thomas P. Grazulis, documentation of tornadoes outside the United States was historically less exhaustive, owing to the lack of monitors in many nations and, in some cases, to internal political controls on public information. Most countries only recorded tornadoes that produced severe damage or loss of life. Consequently, available documentation in 1973 mainly covered the United States. On average, most recorded tornadoes, including the vast majority of significant—F2 or stronger—tornadoes, form in the U.S., although as many as 500 may take place internationally. Some locations, like Bangladesh, are as prone to violent tornadoes as the U.S., meaning F4 or greater events on the Fujita scale.
This page documents the tornadoes and tornado outbreaks of 1953, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes. This was the first year to record an F5 tornado as well as one of the deadliest tornado seasons in official U.S. records, which go back to 1950.
This page documents the tornadoes and tornado outbreaks of 1949, primarily in the United States. Most recorded tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes.
This page documents the tornadoes and tornado outbreaks of 1942, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes. Also, prior to 1950, tornadoes were not officially surveyed by the U.S. Weather Bureau, which would later become the National Weather Service, and thus had no official rating. All documented significant tornadoes were instead given unofficial ratings by tornado experts like Thomas P. Grazulis.
This page documents the tornadoes and tornado outbreaks of 1947, primarily in the United States. Most recorded tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes.
In the afternoon and early evening hours of May 10, 2008, a large and violent tornado moved through Eastern Oklahoma and western Missouri, striking the communities of Picher, Quapaw, Racine and Granby. Twenty-one people were killed by the tornado and over three hundred more were injured. The tornado produced damage that would later receive an EF4 rating. It was one of nine to receive this rating worldwide in 2008, and was the second-deadliest of the year.
