An extremely rare wintertime tornado outbreak affected the Midwestern United States on January 24, 1967. Of the 30 confirmed tornadoes, 13 occurred in Iowa, nine in Missouri, seven in Illinois, and one in Wisconsin. The outbreak produced, at the time, the northernmost tornado to hit the United States in winter, in Wisconsin, until January 7, 2008. The tornadoes formed ahead of a deep storm system in which several temperature records were broken. The deadliest and most damaging tornado of the outbreak struck Greater St. Louis at F4 intensity, killing three people and injuring 216.
A destructive tornado outbreak occurred on July 2, 1997, in the built-up area of Detroit, Michigan. There were 13 tornadoes in total, 3 dragged through neighborhoods and downtown, hitting northern Detroit between I-96 and Eight Mile Road, Hamtramck and Highland Park. The storms killed 7, caused local flooding, and destroyed houses. 5 of the fatalities were recorded in Grosse Pointe Farms, Michigan, due to straight-line winds of up to 100 mph that blew a gazebo full of people into Lake St. Clair. One tornado formed east of the Detroit River, in Essex County, Ontario, near Windsor, Ontario and caused damage in Windsor and Essex County. The strongest tornado was listed as an F3.
From May 4–10, 1933, a tornado outbreak sequence produced at least 33 tornadoes. Among them was the Beaty Swamp tornado, a violent F4 that struck shortly after midnight CST on May 11, 1933, in Overton County, Tennessee, killing 35 people, injuring 150 others, and devastating the unincorporated communities of Beaty Swamp and Bethsaida. The storm was the second-deadliest tornado in the history of Middle Tennessee, even though it struck a sparsely populated, rural area. The community of Beaty Swamp ceased to exist and does not appear on any current maps. The only landmark that alludes to the former community is Beaty Swamp Road, which intersects Highway 111 in the northeast corner of Overton County. The severe weather event that generated the tornado also produced others, including long-tracked, intense tornadoes or tornado families that devastated portions of Alabama, South Carolina, and Kentucky, killing a combined total of 76 people.
On Thursday, March 27, 1890, a major tornado outbreak struck the Middle Mississippi Valley. To this day, this outbreak is still one of the deadliest tornado events in United States history. At least 24 significant tornadoes, several of which were generated by cyclic supercells, were recorded to have spawned from this system, and at least 185 people were killed by tornadoes that day, including a devastating F4 tornado that struck Downtown Louisville, Kentucky, killing at least 115 people and injuring at least 200 others. Five other violent tornadoes occurred elsewhere, including a long-tracked F4 tornado family that crossed two states, killing 21 people and injuring 200, and two other F4s that killed 14 altogether. A pair of F3s near the Tennessee–Kentucky state line may have killed a combined 37 people.
On August 6, 1969, a destructive tornado outbreak affected portions of north central Minnesota on August 6, 1969. The severe weather event generated 13 confirmed tornadoes, killed 15 people, and caused 109 injuries. To date, the outbreak remains the deadliest on record in the North Woods region of Minnesota. It is also known as the 1969 Minnesota tornado outbreak and the 1969 North Woods tornado outbreak. The most destructive tornado of the outbreak was a 32-mile-long (51 km) violent F4 that leveled miles of timberland and farmland across portions of Crow Wing, Cass, and Aitkin counties in Minnesota, killing at least 12 people and injuring 70 others.
On February 19–20, 1884, one of the largest and most widespread tornado outbreaks in American history occurred over the Southeastern United States, known as the Enigma tornado outbreak due to the uncertain number of total tornadoes and fatalities. Nonetheless, an inspection of newspaper reports and governmental studies published in the aftermath reveals successive, long-tracked tornado families striking Alabama, Georgia, Illinois, Indiana, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee and Virginia, with an estimation of at least 52—and possibly 60 or more—tornadoes.
On April 23–25, 1908, a destructive tornado outbreak affected portions of the Midwestern and Southern United States, including the Great Plains. The outbreak produced at least 31 tornadoes in 13 states, with a total of at least 324 tornado-related deaths. Of these deaths, most were caused by three long-tracked, violent tornadoes—each rated F4 on the Fujita scale and considered to be a tornado family—that occurred on April 24. Most of the deaths were in rural areas, often consisted of African Americans, and consequently may have been undercounted. One of the tornadoes killed 143 people along its path, 73 of them in the U.S. state of Mississippi, making the tornado the third deadliest in Mississippi history, following the 1936 Tupelo F5, with 216 deaths, and the 1840 Natchez tornado, with 317 deaths.
On Monday, April 8, 1957, a widespread tornado outbreak struck the Southeastern United States, particularly the Carolinas, and was responsible for seven deaths and 203 injuries across the region. Most of the activity occurred on either side of the Piedmont, including portions of the Cumberland Plateau. At least 18 tornadoes occurred, including several long-tracked tornado families, one of which included a violent tornado that was retrospectively rated F4 on the Fujita scale. Besides tornadoes, the outbreak also generated other severe weather phenomena such as large hail.
On August 28, 1884, a tornado outbreak, including a family of least five strong tornadoes, affected portions of the Dakota Territory within present-day South Dakota. Among them was one of the first known tornadoes to have been photographed, an estimated F4 on the Fujita scale, that occurred near Howard and exhibited multiple vortices. Another violent tornado also occurred near Alexandria, and three other tornadoes were also reported. A sixth tornado also occurred in present-day Davison County. In all, the tornadoes killed at least seven people and injured at least two others. Contemporary records and survivors' recollections indicate that the storms were F3 or F4 on the Fujita scale, but cannot currently be verified, as official records begin in 1950.
On March 21–22, 1932, a deadly tornado outbreak struck the Midwestern and Southern United States. At least 38 tornadoes—including 27 deadly tornadoes and several long-lived tornado families—struck the Deep South, killing more than 330 people and injuring 2,141. Tornadoes affected areas from Mississippi north to Illinois and east to South Carolina, but Alabama was hardest hit, with 268 fatalities; the outbreak is considered to be the deadliest ever in Alabama, and among the worst ever in the United States, trailing only the Tri-State tornado outbreak in 1925, with 747 fatalities, and the Tupelo–Gainesville outbreak in 1936, with 454 fatalities. The 1932 outbreak is believed to have produced 10 violent tornadoes, eight of which occurred in Alabama alone.
On March 16–17, 1942, a deadly late-winter tornado outbreak struck a large area of the Central and Southern United States. The tornado outbreak killed 149 people and injured at least 1,312. At least five states reported violent tornadoes, from Illinois and Indiana south to Mississippi, beginning with an F4 tornado in the morning in Illinois. Intense activity spread south to the Gulf Coast and north to the Michigan–Indiana border as the day went on. Seven violent tornadoes were reported, one of which was a powerful F5 in Illinois. A long-tracked F4 tornado family in Mississippi claimed 63 lives as well, becoming the deadliest tornado of the outbreak. Another long-lived F4 in Tennessee killed 15 more people, and a series of intense tornadoes caused 23 other deaths in Kentucky. The outbreak also produced 18 tornadoes that caused at least one death, one of the highest such totals for a single outbreak.
On Tuesday, February 23, 1965, a small, localized tornado outbreak affected the southern Florida peninsula. At least four confirmed tornadoes touched down between 10 a.m.–1 p.m. EST (15:00–18:00 UTC); the strongest tornado moved through the Fort Lauderdale area and produced F3 damage on the Fujita scale, injuring six people. In addition, a F1 tornado also moved through northern Broward and southern Palm Beach counties. Two tornadoes also affected Lee County, producing F2 and F1 damage, respectively.
A deadly tornado outbreak affected much of the central and Southern United States from April 29–May 1, 1909. Affecting particularly the Mississippi and Tennessee Valleys, it killed over 150 people, 60 of them in the U.S. state of Tennessee alone. The deadliest and longest-tracked tornado of the outbreak was a violent F4 tornado family that tracked across portions of western Tennessee on April 29, claiming at least 29 lives. Another deadly F4 tornado struck portions of northern Alabama and southern Tennessee early the next day, killing the same number. Other F4s in southern Missouri and southern Illinois on April 29 killed a combined 16 people. Deadly F3s in Georgia and Tennessee from April 30–May 1 killed a total of at least 53 people as well.
The Four-State Tornado Swarm was a destructive outbreak of tornadoes in New England on August 15, 1787. At least five separate tornadoes caused major damage in the states of Connecticut, Rhode Island, Massachusetts, and New Hampshire. Two people were killed by a tornado in Wethersfield, Connecticut, and many were injured throughout New England. This event is considered to be the first true tornado outbreak on record.
On April 29–30, 1924, an outbreak of at least 28 tornadoes—26 of which were significant, meaning F2 or stronger—affected the Southern United States. The tornadoes left 114 dead and at least 1,166 injured, mostly in the Carolinas, with 76 deaths in South Carolina alone, along with 16 in Georgia and 13 in Alabama. Killer tornadoes touched down from Oklahoma and Arkansas to Virginia. The deadliest tornado of the outbreak was a long-lived tornado family that produced F4 damage in rural portions of South Carolina, killing 53 people and injuring at least 534. The tornado is the deadliest ever recorded in South Carolina and is one of the longest-tracked observed in the state, having traveled 105 miles (169 km); some sources list a total path length of 135 mi (217 km), including the segment in Florence County, but this is now believed to have been a separate, F3 tornado.
The March 1875 Southeast tornado outbreak was a deadly tornado outbreak that affected portions of the Southern United States from March 19–20, 1875. At least 19 tornadoes were recorded, including seven that were destructive enough to be rated F4 by Thomas P. Grazulis. The worst damage and most of the deaths occurred in Georgia. Most of the damage appears to have been the result of two tornado families that moved along parallel paths 12 to 15 mi apart through parts of Georgia and South Carolina. These families each consisted of numerous long-tracked, intense tornadoes. The deadliest tornado of the outbreak was an estimated F4 that killed 28–42 people in and near Sparta, Georgia, and Edgefield, South Carolina, on March 20. A separate F4 that followed a similar trajectory may have killed as many as 30. In all, this outbreak killed at least 96 people, injured at least 377, and caused at least $650,000 in losses.
From April 27–29, 1912, a major tornado outbreak generated at least six violent tornadoes in Oklahoma, with near-constant activity until early the next day. At least 15 cities were affected, 40 people died, and 120 others were injured. Tornado researcher Thomas P. Grazulis considered this outbreak to be among the worst on record in the state of Oklahoma, as measured by fatalities and violent tornadoes. At least five strong tornadoes affected Washita County, Oklahoma, during this outbreak.
On April 18–20, 1880, a tornado outbreak impacted the Midwestern United States, producing numerous strong tornadoes, killing at least 166 people, and injuring more than 516 others. The outbreak generated five violent tornadoes, including three long-tracked F4 tornadoes in Missouri that killed at least 144 people. Two of the tornadoes followed parallel paths and occurred simultaneously near Springfield, one of which devastated the town of Marshfield, causing 92 fatalities there. Other deadly, intense tornadoes occurred in the Great Lakes region and in Arkansas, including another F4 tornado that destroyed a third of El Paso, Arkansas, killing four or more people.
On April 9, 1919, a tornado outbreak occurred in the Southern Great Plains of the US, producing numerous strong tornadoes and killing at least 92 people, mainly in portions of North and East Texas. The entire outbreak occurred overnight and produced at least seven intense, deadly tornadoes, the deadliest of which was a long-tracked, extremely violent F4 in East Texas that killed 24 people and injured 100 others. A separate F4 long-tracker in the same region killed 17 others and injured 60 more. A deadly F3 also claimed nine or more lives in southern Oklahoma, and a long-lived F3 in East Texas crossed into Arkansas, killing eight. Several of the tornadoes in this outbreak may have been families of two or more twisters.
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.
