On April 10–12, 1965, a historic severe weather event affected the Midwestern and Southeastern United States. The tornado outbreak produced 55 confirmed tornadoes in one day and 16 hours. The worst part of the outbreak occurred during the afternoon hours of April 11 into the overnight hours going into April 12. The second-largest tornado outbreak on record at the time, this deadly series of tornadoes, which became known as the 1965 Palm Sunday tornado outbreak, inflicted a swath of destruction from Cedar County, Iowa, to Cuyahoga County, Ohio, and a swath 450 miles long (724 km) from Kent County, Michigan, to Montgomery County, Indiana. The main part of the outbreak lasted 16 hours and 35 minutes and is among the most intense outbreaks, in terms of tornado strength, ever recorded, including at least four "double/twin funnel" tornadoes. In all, the outbreak killed 266 people, injured 3,662 others, and caused $1.217 billion in damage.
On April 5–6, 1936, an outbreak of 14 tornadoes struck the Southeastern United States, killing at least 454 people and injuring at least 2,500 others. Over 200 people died in Georgia alone, making it the deadliest disaster ever recorded in the state.
From April 9–11, 1947, a significant tornado outbreak produced catastrophic effects over portions of the southern Great Plains, in the contiguous United States. The outbreak generated at least 12, and possibly 17 or more, tornadoes, many of which were significant. On Wednesday, April 9, a series of related tornadoes spawned by a single supercell, dubbed the Glazier–Higgins–Woodward tornadoes, swept through the U.S. states of Texas, Oklahoma, and Kansas. Most of the damage and all the deaths are still blamed on one large tornado, known as the Glazier–Higgins–Woodward tornado, that traveled 98 mi (158 km) from Texas to Oklahoma, beginning over the South Plains. This event, up to nearly 2 mi (3.2 km) in width, was often compared to the Tri-State tornado, because it was originally thought to have left a 198-to-221-mile-long path, was similarly large and intense for much of its path, and was also retroactively rated F5 on the modern-day Fujita scale, but it is now believed to have been part of a 125-to-170-mile-long family of nine or 10 tornadoes.
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 August 6, 1969, a destructive tornado outbreak affected portions of the Upper Midwest—principally north-central Minnesota—on August 6, 1969. The severe weather event generated 14 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 33-mile-long (53 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 March 28, 1920, a large outbreak of at least 37 tornadoes, 31 of which were significant, took place across the Midwestern and Southern United States. The tornadoes left at least 153 dead and at least 1,215 injured. Many communities and farmers alike were caught off-guard as the storms moved to the northeast at speeds that reached over 60 mph (97 km/h). Most of the fatalities occurred in Georgia (37), Ohio (28), and Indiana (21), while the other states had lesser totals. Little is known about many of the specific tornadoes that occurred, and the list below is only partial.
A violent severe weather outbreak struck the Southeast on April 4–5, 1977. A total of 22 tornadoes touched down with the strongest ones occurring in Mississippi, Alabama, and Georgia. The strongest was a catastrophic F5 tornado that struck the northern Birmingham, Alabama, suburbs during the afternoon of Monday, April 4. In addition to this tornado, several other tornadoes were reported from the same system in the Midwest, Alabama, Georgia, Mississippi and North Carolina. One tornado in Floyd County, Georgia, killed one person, and another fatality was reported east of Birmingham in St. Clair County. In the end, the entire outbreak directly caused 24 deaths and 158 injuries. The storm system also caused the crash of Southern Airways Flight 242, which killed 72 and injured 22.
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 51—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 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 751 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 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.
On April 19–21, 1920, a multi-day severe weather event affected the Southeastern United States. The most intense portion of the outbreak occurred on the morning of April 20. At least seven tornadoes affected the American U.S. states of Mississippi, Alabama, and Tennessee, six of them rated violent F4s on the Fujita scale. The tornado outbreak killed at least 243 people.
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.
A widespread, destructive, and deadly tornado outbreak sequence affected the Southeastern United States from April 28 to May 2, 1953, producing 24 tornadoes, including five violent F4 tornadoes. The deadliest event of the sequence was an F4 tornado family that ravaged Robins Air Force Base in Warner Robins, Georgia, on April 30, killing at least 18 people and injuring 300 or more others. On May 1, a pair of F4 tornadoes also struck Alabama, causing a combined nine deaths and 15 injuries. Additionally, another violent tornado struck rural Tennessee after midnight on May 2, killing four people and injuring eight. Additionally, two intense tornadoes impacted Greater San Antonio, Texas, on April 28, killing three people and injuring 20 altogether. In all, 36 people were killed, 361 others were injured, and total damages reached $26.713 million (1953 USD). There were additional casualties from non-tornadic events as well, including a washout which caused a train derailment that injured 10.
On November 7–8, 1957, a significant tornado outbreak affected portions of the Southern United States, particularly the Golden Triangle of Southeast Texas and parts of Acadiana in Louisiana. The severe weather event inflicted 12 deaths and more than 200 injuries, especially in the vicinity of Beaumont and Port Arthur, Texas. The most intense tornado of the outbreak, retrospectively rated F4 on the Fujita scale, struck the town of Orange, Texas, killing one person, injuring 81 others, and causing $11⁄2 million in losses. The deadliest tornado of the outbreak was an F3 that killed four people northwest of Carencro, Louisiana. The costliest tornado of the outbreak, also rated F3, caused $2.3 million in losses in the town of Groves, Texas, killing a few people there. Other intense tornadoes occurred as far east as Mississippi and North Carolina. In all, at least 28 tornadoes were confirmed, yet others were likely present as well.
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.
Several destructive tornadoes struck the Southeastern United States, primarily along and east of the Lower Mississippi Valley, on February 13, 1952. Multiple intense tornadoes touched down throughout the day, three of which were killers. The deadliest and most destructive tornado of the outbreak was a violent F4 that touched down in south-central Tennessee, killing three people and injuring 44 others. A similarly destructive tornado—albeit of weaker, F2 intensity—formed from the same storm as the preceding F4 and became the second costliest of the outbreak. Another intense tornado affected the Mississippi embayment near Manila, Arkansas, injuring five people, and a pair of deadly F3s in Alabama claimed a combined two lives. In all, the outbreak killed five people and injured 102 others.
This page documents the tornadoes and tornado outbreaks of 1948, 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 1946, 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.
The following is a list of weather events that occurred on Earth in the year 1946. There were several natural disasters around the world from various types of weather, including blizzards, cold waves, droughts, heat waves, wildfires, floods, tornadoes, and tropical cyclones.
