List of North American tornadoes and tornado outbreaks

From Wikipedia, the free encyclopedia

Tornadoes in the United States 1950-2019

These are some notable tornadoes, tornado outbreaks, and tornado outbreak sequences that have occurred in North America.

  1. The listing is U.S.-centric, with greater and more consistent information available for U.S. tornadoes. Some North American outbreaks affecting the U.S. may only include tornado information from the U.S.
  2. Exact death and injury counts are not possible, especially for large events and events before 1950.
  3. Prior to 1950 in the United States, only significant tornadoes (rated F2 or higher or causing a fatality) are listed for the number of tornadoes in outbreaks. These ratings are estimates from tornado expert Tom Grazulis and are not official.
  4. Due to increasing detection, particularly in the U.S., numbers of counted tornadoes have increased markedly in recent decades although number of actual tornadoes and counted significant tornadoes has not. In older events, the number of tornadoes officially counted is likely underestimated.
  5. Historical context: Much of the tornado activity in the American Midwestern area is relatively unknown and significantly under-reported prior to the middle of the 1800s as few people lived there to record the yearly activity. The American government did not acquire the Midwestern states area until the 1803 Louisiana Purchase from the French government. The Louisiana Purchase area included major tornado activity areas of north Texas, Oklahoma, Kansas, Nebraska, Arkansas, Missouri, Iowa, South Dakota, and lower Minnesota. Large groups of settlers and pioneers only began populating the region after 1820. As these areas began being more populated, existing tornado activity there became more known and reported through newspaper and telegraph.

Where applicable, a count of the number of significant (F2/EF2 and stronger), violent (F4/EF4 and stronger), and killer tornadoes is included for outbreaks.

Essex County, Massachusetts–Hampton, New Hampshire tornado July 5, 1643 Essex County, Massachusetts, Hampton, New Hampshire - 1 fatality Potential earliest recorded U.S. tornado and fatality. Event was recorded by Massachusetts Bay Colony governor John Winthrop. "There arose a sudden gust at N.W. so violent for half an hour as it blew down multitudes of trees. It lifted up their meeting house at Newbury, the people being in it. It darkened the air with dust, yet through God's great mercy it did no hurt, but only killed one Indian with the fall of a tree. It was straight between Linne [Lynn] and Hampton."[1]

Tornado outbreak of April 4–7, 2022 April 4–7 2022 Southern United States 89 1 For the third straight week another tornado outbreak affected the same areas affected by the previous two outbreaks. Several tornadoes touched down mostly in the Dallas–Fort Worth metroplex on April 4, before a much more significant outbreak occurred in Mississippi, Alabama, Georgia, and South Carolina the next day. Several tornadoes touched down from a mesoscale convective system that swept eastward on March 5, while numerous large, long-tracked, intense tornadoes were spawned by supercells that formed ahead of the squall line. One person was killed by a large, violent EF4 tornado in Black Creek, Georgia, while three separate EF3 tornadoes impacted Allendale, South Carolina; Ulmer, South Carolina; and Bonaire, Georgia. A second wave of weak tornadoes also struck Georgia and Florida on April 6–7. (14 significant, 1 violent killer)
April 2022 North American storm complex April 11–13 2022 Southern United States, Midwestern United States 74 0 Isolated severe weather over Arkansas on April 11 gave way to a more significant severe weather event in Texas and the Upper Midwest on April 12 followed by a large severe weather outbreak on April 13. Four weak tornadoes were confirmed in Arkansas on April 11. More significant tornadoes occurred on April 12, including a high-end EF3 tornado in Bell County, Texas, that resulted in 23 injuries and several strong tornadoes over northern Iowa and southeastern Minnesota. More tornadoes occurred across primarily Mississippi, Alabama, and Kentucky on April 13, accompanied by a widespread damaging wind event. (6 significant)
May 2022 Midwest derecho May 12 2022 Midwestern United States 32 0 A derecho produced an outbreak of tornadoes across the Dakotas and Minnesota. An EF1 tornado quickly spun up near Thomas, South Dakota, forcing the residents of homes who were outside to seek shelter under a tractor, resulting in an injury. A strong EF2 rope tornado struck Castlewood, causing heavy damage and also injuring one person. A high-end EF2 tornado near Gary struck a farm, heavily damaging the house and damaging a number of other farm buildings and vehicles, injuring another person. Although none of the tornadoes were fatal, the event as a whole caused five deaths and at least 13 injuries. (5 significant)
Tornado outbreak of November 4–5, 2022 November 4–5 2022 Southern United States, Midwestern United States 31 2 An intense late-season tornado outbreak affected northeastern Texas, southeastern Oklahoma, northwestern Louisiana, and western Arkansas on November 4. Numerous large, intense, long-tracked tornadoes touched down and two tornado emergencies were issued for Idabel, Oklahoma, and New Boston, Texas, respectively. One death each was recorded in Pickens, Oklahoma, and Cason, Texas, respectively, as well as numerous injuries. (11 significant, 2 violent, 2 killer)
Tornado outbreak of November 29–30, 2022 November 29–30 2022 Southern United States 25 2 An overnight tornado outbreak affected Louisiana, Mississippi, and Alabama.

(6 significant, 1 killer)
Tornado outbreak of December 12–15, 2022 December 12–15 2022 Southern United States 73 3 A widespread tornado outbreak produced numerous strong tornadoes across portions of the southern United States. An EF3 tornado caused significant damage near Farmerville, Louisiana, while an EF2 tornado struck near Keatchie, Louisiana, killing two people. Another EF2 tornado struck near Killona, Louisiana, killing one and a damaging EF2 tornado impacted the New Orleans metro, following a path similar to a high-end EF3 tornado from March 22, 2022. Numerous other weak tornadoes also touched down. (21 significant, 2 killer)
Tornado outbreak of January 12, 2023 January 12 2023 Southeastern United States 38 8 A significant tornado outbreak took place primarily across Alabama and Georgia during the morning and afternoon of January 12. One supercell produced 10 tornadoes that produced moderate to severe damage from south-central Alabama to west-central Georgia, especially in Selma, Alabama, and Autauga County, Alabama, and as well as LaGrange, Griffin, Experiment, and the Jackson Lake area in Georgia. An EF3 tornado in Autauga County, Alabama resulted in seven fatalities before moving through several counties to the northeast, while an EF2 tornado in the Jackson Lake area in Georgia killed one person (the tornado was also responsible for an indirect death the next day). Elsewhere, other tornadoes caused damage in Sumter and Mobile counties in Alabama, as well as parts of Tennessee, Kentucky, Illinois, and the Carolinas. (12 significant, 2 killer)
2023 Pasadena–Deer Park tornado January 24 2023 Southeast Texas 1 0 Rare low-end EF3 tornado struck Pasadena and Deer Park, Texas, injuring three and causing $6.6 million in damage.

February 2023 North American storm complex February 26–27 2023 South Central United States, Midwestern United States 30 1 Several tornadoes occurred across the Great Plains and Midwestern United States. On February 26, three EF2 tornadoes touched down in Oklahoma. The first one caused a fatality and significant damage near the town of Cheyenne, while the other two struck Norman and Shawnee respectively. (3 significant, 1 killer)
Early-March 2023 North American storm complex March 1–3 2023 Southern United States, Midwestern United States 33 0 Numerous tornadoes touched down across the Southern United States to the Great Lakes region. On March 2, an EF2 tornado caused significant damage near Kirby, Arkansas. The next day, an EF2 tornado caused significant damage near Fremont, Kentucky. (2 significant)
Tornado outbreak of March 24–27, 2023 March 24–27 2023 Southeastern United States 35 23 A slow-moving system sparked a small, but destructive four-day outbreak of tornadoes. One supercell in Mississippi on March 24 produced three large long-tracked tornadoes, the first of which was a violent, very high-end EF4 tornado that struck Rolling Fork, Midnight, and Silver City, killing 17 people. The storm then produced an EF3 tornado that struck Black Hawk and Winona, killing three people. A subsequent EF3 tornado from the storm killed two people as it passed near or moved directly through Egypt, New Wren, Amory, and Smithville. An early-morning EF2 tornado also killed a person on the north side of Hartselle, Alabama. Scattered tornado activity continued throughout the rest of the outbreak and a few strong tornadoes touched down, including another EF3 tornado that caused major damage in North West Point, Georgia, injuring five people. (9 significant, 1 violent, 4 killer)
Tornado outbreak of March 31 – April 1, 2023 March 31 – April 1 2023 Midwestern United States, Southern United States, Eastern United States 147 26 A catastrophic, historic, and deadly tornado outbreak produced widespread tornadic activity across large portions of the Midwestern, Southern and Eastern United States. On March 31, the SPC issued two tornado-driven high risk areas; the first was in southeastern Iowa, northwestern Illinois, and far northeastern Missouri, while the second included eastern Arkansas, southwestern Tennessee, and northern Mississippi. That afternoon, numerous tornadic supercells developed over the northern high-risk area, producing numerous tornadoes, including an EF3 tornado near Martinsburg, Iowa, and a low-end EF4 tornado that swept away a home near Keota. Over a dozen EF2 tornadoes also touched down and one EF1 tornado collapsed the roof of Apollo Theatre in Belvidere, Illinois, during a sold-out concert, killing one person and injuring over three dozen people. Other tornadoes also touched down in Indiana that evening, including multiple EF3 tornadoes, one of which struck Robinson, Illinois, and Sullivan, Indiana, killing six people while another one killed two people near Spencer, Indiana. To the south, supercell development was much more isolated, but the storms that did form were discrete and produced very large, long-tracked, intense tornadoes. This included a long-tracked high-end EF3 tornado that moved through the Little Rock, Arkansas metropolitan, injuring dozens of others (one indirect fatality also occurred). Other deadly, intense, long-tracked tornadoes caused fatalities in or near Wynne, Arkansas, Covington, Tennessee, Adamsville, Tennessee, Pontotoc, Mississippi, and Hazel Green, Alabama. Later that afternoon on April 1, a localized, but intense outbreak of 10 tornadoes struck the Delaware Valley along with Central and South Jersey. An extremely rare EF3 tornado killed a person in Sussex County, Delaware, while three EF2 tornadoes touched down in New Jersey. Along with the tornadoes, hundreds of damaging wind, large hail, and flooding reports were received while areas on the back side of the system had either wildfires or a blizzard. (44 significant, 1 violent, 9 killer)
Tornado outbreak sequence of June 14–19, 2023 June 14–19 2023 Midwestern United States, Southern United States, Eastern United States 72 4 A multi-day outbreak sequence of significant tornado and severe weather activity occurred across the south central and southeastern United States, as well as the Ohio Valley. On June 15, an EF3 tornado struck the city of Perryton, Texas, resulting in major damage and three fatalities, along with up to 100 injuries. A cluster of supercells also produced 13 tornadoes in southeastern Michigan and northern Ohio, including three that were rated EF2 (one of which struck northern Toledo) and another EF2 tornado struck Pensacola Beach, Florida that night. Three days later on June 18 an outbreak of 22 tornadoes struck mainly the southeastern United States (a rarity for that region during that time of year). An EF3 tornado produced significant damage near the town of Louin, Mississippi, killing one and injuring 25. Three other EF2 tornadoes also touched down. (14 significant, 2 killer)
Tornado outbreak sequence of June 20–26, 2023 June 20–26 2023 South Central United States, Midwestern United States, Eastern United States, Manitoba, Ontario 93 5 Another wave of significant tornado and severe weather activity occurred immediately after the previous one across mostly the northern United States and Ohio Valley, as well as Manitoba and Ontario in Canada, although many of the tornadoes moved over open terrain and were unratable. June 21 featured 43 mostly brief, unratable tornadoes, but 36 of them touched down in Colorado, making it the largest single-day outbreak in the state's history. All but three of these tornadoes touched down in Washington County, including 27 tornadoes alone near Akron, and three of them were rated EF2. Further to the south, a destructive high-end EF3 tornado struck the west side of Matador, Texas, killing four people. Several strong tornadoes touched down on June 23, including an EF3 tornado southwest of Granada, Colorado, the first tornado of such strength in the state since 2015, and an EF2 tornado that struck North Antelope Rochelle Mine in Wyoming, injuring eight people. Nine tornadoes touched down across three states and Ontario on June 25, including an EF2 tornado that killed a person in Rusk, Indiana. (12 significant, 2 killer)

On December 9, a large EF3 tornado caused major damage in Clarksville, Tennessee, killing four people. Later that evening, an EF2 tornado produced significant damage in Madison, Hendersonville and Gallatin, Tennessee, killing three people and prompting a tornado emergency. (5 significant, 2 killer)
Tornado outbreak of January 8-9, 2024 January 8-9 2024 Southern United States 35 2 An outbreak of tornadoes affected several areas across the southern United States. The strongest of which was an intense waterspout that produced EF3 damage after moving ashore in Panama City Beach, Florida in the early morning hours of January 9. Later that day, an EF2 tornado killed a person near Cottonwood, Alabama, and an EF1 tornado killed a person near Claremont, North Carolina. (7 significant, 2 killer)
Tornado outbreak of March 13–15, 2024 March 13-15 2024 Midwestern United States, Southern United States 32 3 Numerous tornadoes affected areas across the midwestern and southern United States.
