These are some notable tornadoes, tornado outbreaks, and tornado outbreak sequences that have occurred around the globe.
- Exact death and injury counts are not possible; especially for large events and events before 1955.
- Prior to 1950 in the United States, only significant tornadoes are listed for the number of tornadoes in outbreaks.
- Due to increasing detection, particularly in the U.S., numbers of counted tornadoes have increased markedly in recent decades although the number of actual tornadoes and counted significant tornadoes has not. In older events, the number of tornadoes officially counted is likely underestimated.
Hurricane Agnes was the costliest hurricane to hit the United States at the time, causing an estimated $2.1 billion in damage. The hurricane's death toll was 128. The effects of Agnes were widespread, from the Caribbean to Canada, with much of the east coast of the United States affected. Damage was heaviest in Pennsylvania, where Agnes was the state's wettest tropical cyclone. Due to the significant effects, the name Agnes was retired in the spring of 1973.
Hurricane Rita was the most intense tropical cyclone on record in the Gulf of Mexico and the fourth-most intense Atlantic hurricane ever recorded. Part of the record-breaking 2005 Atlantic hurricane season, which included three of the top ten most intense Atlantic hurricanes in terms of barometric pressure ever recorded, Rita was the seventeenth named storm, tenth hurricane, and fifth major hurricane of the 2005 season. It was also the earliest-forming 17th named storm in the Atlantic until Tropical Storm Rene in 2020. Rita formed near The Bahamas from a tropical wave on September 18, 2005 that originally developed off the coast of West Africa. It moved westward, and after passing through the Florida Straits, Rita entered an environment of abnormally warm waters. Moving west-northwest, it rapidly intensified to reach peak winds of 180 mph (285 km/h), achieving Category 5 status on September 21. However, it weakened to a Category 3 hurricane before making landfall in Johnson's Bayou, Louisiana, between Sabine Pass, Texas and Holly Beach, Louisiana, with winds of 115 mph (185 km/h). Rapidly weakening over land, Rita degenerated into a large low-pressure area over the lower Mississippi Valley by September 26th.
Hurricane Cindy was a tropical cyclone that briefly reached minimal hurricane strength in the Gulf of Mexico during July in the 2005 Atlantic hurricane season and made landfall in Louisiana. It was the third named storm and first hurricane of the season. Cindy was originally thought to have been a tropical storm at peak strength, but was upgraded to a Category 1 hurricane in the post-season analysis. Cindy formed on July 3 just east of the Yucatán Peninsula in the Caribbean Sea. The depression soon made landfall on the peninsula and weakened before reemerging in the Gulf of Mexico on July 4. The storm strengthened as it moved north becoming a hurricane just before making landfall near Grand Isle, Louisiana, on July 5. The storm weakened as it moved overland and became extratropical on July 7.
Tropical Storm Bill was a tropical storm that affected the Gulf Coast of the United States in the summer of 2003. The second storm of the 2003 Atlantic hurricane season, Bill developed from a tropical wave on June 29 to the north of the Yucatán Peninsula. It slowly organized as it moved northward, and reached a peak of 60 miles per hour (97 km/h) shortly before making landfall in south-central Louisiana. Bill quickly weakened over land, and as it accelerated to the northeast, moisture from the storm, combined with cold air from an approaching cold front, produced an outbreak of 34 tornadoes. Bill became extratropical on July 2, and was absorbed by the cold front later that day.
Hurricane Bob was the first of six hurricanes to strike the United States during the 1985 Atlantic hurricane season. The second tropical storm and first hurricane of the year, Bob developed from a tropical wave on July 21 in the eastern Gulf of Mexico. Bob began moving east, making landfall southwestern Florida as a weak tropical storm. The storm then turned to the north and quickly intensified to hurricane status on July 24. The next day, it made landfall near Beaufort, South Carolina, becoming one of a record-tying six hurricanes to hit the United States during a single season. Bob quickly weakened over land, and was absorbed by a frontal trough over eastern West Virginia on July 26.
The 2003 South Dakota tornado outbreak, known locally as "Tornado Tuesday", was a tornado outbreak that occurred in the southeastern and east central part of South Dakota in the United States on June 24, 2003. At the time, this outbreak tied a United States record for the most tornado touchdowns in a single day for one state, with 67. The event was part of a larger outbreak that produced 125 tornadoes. However this record was surpassed by a tornado outbreak in Kansas on May 23, 2008, when 73 tornadoes hit the state, including two that started in Oklahoma. It was also the largest tornado outbreak ever recorded in the astronomical summer period that was not related to a tropical cyclone.
The Hurricane Ivan tornado outbreak was a three-day tornado outbreak that was associated with the passage of Hurricane Ivan across the Southern United States starting on September 15, 2004, across the Gulf Coast states of Alabama and Florida as well as southern Georgia before ending in the Middle Atlantic Coast on September 18.
Tropical Storm Arthur was the first tropical cyclone and named storm of the annual Atlantic hurricane season that caused minimal flooding in the Carolinas in mid-June 1996. Arthur originated from an area of increased convection east of the Bahamas on June 16. Gradually, the system increased in organization, and was designated as a tropical depression on June 17. The depression tracked north-northwest and became Tropical Storm Arthur while just offshore the Southeastern United States on June 19. Later that day, Arthur peaked with maximum sustained winds of 45 mph (75 km/h), but weakened slightly before making landfall in North Carolina early the following day. After striking North Carolina, Arthur tracked out to sea and weakened further to a tropical depression. By June 21, Arthur transitioned into an extratropical cyclone. Overall, impact from Arthur was minimal, limited to light rainfall and moderate surf in North and South Carolina, as well as a tornado in Florida. Total damage amounted to $1 million (1996 USD), but no fatalities were reported.
The Hurricane Frances tornado outbreak was a widespread tornado outbreak associated with Hurricane Frances that came ashore on eastern Florida on September 4–5, 2004. Outer bands from the hurricane and its remnants, when it moved across the Appalachian Mountains, produced one of the largest tornado outbreaks ever spawned by a tropical cyclone in the United States in terms of number of tornadoes confirmed since records were kept in 1950. In addition, it was the largest tornado outbreak in South Carolina history, with nearly half of the tornadoes in that state.
Tropical Storm Becky was the second tropical cyclone and named storm of the 1970 Atlantic hurricane season. Becky formed from a tropical depression that was designated on July 19. The next day it organized over the Yucatán Channel and became Tropical Storm Becky. Initially thought to have attained minimal hurricane status, Becky reached peak winds of 65 mph (100 km/h), but the storm began to deteriorate shortly thereafter. The storm made landfall on the Florida Panhandle on July 22, and rapidly weakened over land. Overall, damage was related to heavy rainfall that caused flooding in Tallahassee, Florida; 104 families suffered flood-related losses. About $500,000 in damage was attributed to the storm. Further north, the heavy rainfall swelled rivers. Becky may have been partially responsible for spawning tornadoes that destroyed or damaged several houses.
On June 18–19, 1972, Hurricane Agnes generated the third-deadliest tropical cyclone-related tornado outbreak in the United States since 1900, as well as the deadliest such tornado outbreak on record in Florida. The outbreak lasted about 38 hours and produced at least 19 confirmed tornadoes, though some studies suggested nearly a dozen more. Two of the tornadoes killed a total of seven people and were not classified as tornadoes by the National Weather Service until 2018. In Florida alone, the outbreak inflicted at least 135 injuries and destroyed 15 homes, while 119 homes received damage. Statewide, 217 trailers were destroyed and 196 trailers incurred damage. Additionally, six businesses were destroyed, while six others were damaged.
This page documents the tornadoes and tornado outbreaks of 2011. Extremely destructive tornadoes form most frequently in the United States, Bangladesh, Brazil and Eastern India, but they can occur almost anywhere under the right conditions. Tornadoes also appear regularly in neighboring southern Canada during the Northern Hemisphere's summer season, and somewhat regularly in Europe, Asia, and Australia.
The Hurricane Rita tornado outbreak was a significant tropical cyclone-produced tornado outbreak and severe weather event that resulted from the remnants of Hurricane Rita in late-September 2005. The event was the fourth-largest tornado outbreak caused by a tropical cyclone in recorded history. After the hurricane made landfall on the extreme southwestern coast of Louisiana on September 24, the tropical cyclone's strong rainbands affected much of the West South Central and East South Central States, producing heavy rainfall in addition to numerous tornadoes. Tornadic activity was distributed roughly evenly from September 24–25, though activity shifted slightly eastward on September 25. The severe activity ended by September 26, by which time the remnants of Hurricane Rita were absorbed by a frontal boundary.
Tropical Storm Nestor was a large but short-lived and disorganized tropical storm which caused widespread tornadoes and heavy rain in the Southeastern United States during mid-October 2019. The sixteenth depression and fourteenth named storm of the erratic 2019 Atlantic hurricane season, Nestor originated from a broad area of low pressure over the Western Caribbean. It emerged in the Gulf of Mexico and began to organize slightly, becoming Potential Tropical Cyclone Sixteen due to its threat to the Southeastern United States. It gained a sufficient enough of a circulation to be designated Tropical Storm Nestor near the Florida Panhandle early on October 18, crawling to the northeast, and then finally transitioning into an extratropical cyclone due to strong shear from a nearby upper-level low before making landfall on the Florida Panhandle on October 19.
