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.
This page documents notable tornadoes and tornado outbreaks worldwide in 2006. Strong and destructive tornadoes form most frequently in the United States, Bangladesh, and Eastern India, but they can occur almost anywhere under the right conditions. Tornadoes also develop occasionally in southern Canada during the Northern Hemisphere's summer and somewhat regularly at other times of the year across Europe, Asia, Argentina, Brazil and Australia. Tornadic events are often accompanied with other forms of severe weather, including strong thunderstorms, strong winds, and hail.

Tropical Storm Hermine was the eighth tropical cyclone and named storm of the 1998 Atlantic hurricane season. Hermine developed from a tropical wave that emerged from the west coast of Africa on September 5. The wave moved westward across the Atlantic Ocean, and on entering the northwest Caribbean interacted with other weather systems. The resultant system was declared a tropical depression on September 17 in the central Gulf of Mexico. The storm meandered north slowly, and after being upgraded to a tropical storm made landfall on Louisiana, where it quickly deteriorated into a tropical depression again on September 20.
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.
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.
Tropical Storm Candy produced minor impact in the state of Texas during the 1968 Atlantic hurricane season. The third tropical cyclone of the annual season, it developed from a tropical disturbance in the southwestern Gulf of Mexico on June 22. Gradual strengthening occurred, with the depression becoming Tropical Storm Candy on the following day. The storm reached its peak intensity of 70 mph (110 km/h) later that day and made landfall Port Aransas, Texas on June 23. Candy weakened into a tropical depression only hours after moving inland. However, the system remained a designated cyclone until June 26, at which time it completed extratropical transition over the state of Michigan.
This page documents the tornadoes and tornado outbreaks of 2010. The majority of tornadoes form in the U.S., but they can occur almost anywhere under the right conditions. A lesser number occur outside the U.S., most notably in parts of neighboring southern Canada during the Northern Hemisphere's summer season, but are also known in South America, Europe, Asia, and Australia.
Tropical Storm Hermine was a near-hurricane strength tropical cyclone that brought widespread flooding from Guatemala northwards to Oklahoma in early September 2010. Though it was named in the western Gulf of Mexico, Hermine developed directly from the remnant low-pressure area associated with the short-lived Tropical Depression Eleven-E in the East Pacific. Throughout its lifespan, the storm caused 52 direct deaths and roughly US$740 million in damage to crops and infrastructure, primarily in Guatemala. The precursor tropical depression formed on September 3 in the Gulf of Tehuantepec and neared tropical storm intensity before making landfall near Salina Cruz, Mexico, on the next day. Though the depression quickly weakened to a remnant low, the disturbance crossed the Isthmus of Tehuantepec and tracked north into the warm waters of the Gulf of Mexico, where it reorganized into a tropical cyclone once again on September 5. There, the system quickly strengthened into a tropical storm and received the name Hermine before moving ashore near Matamoros, Mexico on September 7 as a high-end tropical storm. Over the next few days, Hermine weakened as it moved over the U.S. Southern Plains, eventually dissipating over Kansas on September 10.
The October 2010 North American storm complex is the name given to a historic extratropical cyclone that impacted North America. The massive storm complex caused a wide range of weather events including a major serial derecho stretching from the Gulf Coast to the Great Lakes, a widespread tornado outbreak across the Southeast United States and Midwest and a blizzard across portions of the Canadian Prairies and the Dakotas. The cyclone's lowest minimum pressure of 955.2 mb (28.21 inHg) made it the second most intense non-tropical system recorded in the continental United States (CONUS). The lowest confirmed pressure for a non-tropical system in the continental United States was set by a January 1913 Atlantic coast storm.
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.
Tropical Storm Debra was the second of two tropical storms to hit the United States in the 1978 Atlantic hurricane season. The fourth named storm of the season, Debra developed from the interaction between a high-altitude cold low and a lower tropical wave in the Gulf of Mexico. Forming on August 25, it was upgraded to Tropical Storm Debra based on data from a Hurricane Hunter aircraft. As Debra approached the coast, it attained peak winds of 60 mph (95 km/h). The storm made landfall on the coast of Louisiana, east of the Texas border. Two deaths were caused by the storm. Debra weakened as it moved inland and ultimately dissipated on August 29 over Arkansas.
Hurricane Hermine was the first hurricane to make landfall in Florida since Hurricane Wilma in 2005, and the first to develop in the Gulf of Mexico since Hurricane Ingrid in 2013. The ninth tropical depression, eighth named storm, and fourth hurricane of the 2016 Atlantic hurricane season, Hermine developed in the Florida Straits on August 28 from a long-tracked tropical wave. The precursor system dropped heavy rainfall in portions of the Caribbean, especially the Dominican Republic and Cuba. In the former, the storm damaged more than 200 homes and displaced over 1,000 people. Although some areas of Cuba recorded more than 12 in (300 mm) of rain, the precipitation was generally beneficial due to a severe drought. After being designated on August 29, Hermine shifted northeastwards due to a trough over Georgia and steadily intensified into an 80 mph (130 km/h) Category 1 hurricane just before making landfall in the Florida Panhandle during September 2. After moving inland, Hermine quickly weakened and transitioned into an extratropical cyclone on September 3 near the Outer Banks of North Carolina. The remnant system meandered offshore the Northeastern United States before dissipating over southeastern Massachusetts on September 8.
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.
