The tornado outbreak sequence of May 2004 was a series of tornado outbreaks that affected much of southern Ontario, the Central and Southern United States from east of the Rockies to the Mid-Atlantic States from May 21 to May 31, 2004. Particularly hard hit were the central Plains from Missouri to Iowa and the Ohio Valley. The Central Plains were hit by two significant outbreaks on May 22 and May 24, the first outbreak of which produced a very large and violent tornado in Hallam, Nebraska. The Ohio Valley was affected by one of the largest tornado outbreaks ever during the Memorial Day weekend on May 29–30.
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.
The Daulatpur–Saturia tornado occurred in Manikganj District, Bangladesh on 26 April 1989. There is great uncertainty about the death toll, but official estimates from the World Meteorological Organization indicate that it was devastating and that it killed approximately 1,300 people, which would make it the deadliest tornado in history. In 2022, this tornado's status as the deadliest tornado in history was challenged, claiming it did not kill more than 922 people. The tornado affected the cities of Daulatpur and Saturia the most, moving east through Daulatpur and eventually northeast into Saturia. Previously, the area that the tornado hit had been in a state of drought for six months.
This page documents notable tornadoes and tornado outbreaks worldwide in 2003. 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, and Australia. Tornadic events are often accompanied with other forms of severe weather, including strong thunderstorms, strong winds, and hail.
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.
The 1989 North Indian Ocean cyclone season was a below-average season in annual cycle of tropical cyclone formation. Despite this, the season had the second highest Accumulated Cyclone Energy in the basin on record behind only 2019 and 2023. The season has no official bounds but cyclones tend to form between April and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. There are two main seas in the North Indian Ocean—the Bay of Bengal to the east of the Indian subcontinent and the Arabian Sea to the west of India. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center (JTWC) releases unofficial advisories. An average of five tropical cyclones form in the North Indian Ocean every season with peaks in May and November. Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD.
Severe Cyclonic Storm Aila was the second named tropical cyclone of the 2009 North Indian Ocean cyclone season. Warned by both the Regional Specialized Meteorological Center (RMSC) and Joint Typhoon Warning Center (JTWC), Aila formed over a disturbance over the Bay of Bengal on May 23, 2009 and started to intensify and organize reaching sustained wind speeds of 110 kmh (70 mph). It was the worst natural disaster to affect Bangladesh since Cyclone Sidr in November 2007. A relatively strong tropical cyclone, it caused extensive damage in India and Bangladesh.
This page documents the tornadoes and tornado outbreaks of 1989, 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.
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 2011 Super Outbreak was the largest, costliest, and one of the deadliest tornado outbreaks ever recorded, taking place in the Southern, Midwestern, and Northeastern United States from April 25 to 28, 2011, leaving catastrophic destruction in its wake. Over 175 tornadoes struck Alabama, Mississippi, and Tennessee, which were the most severely damaged states. Other destructive tornadoes occurred in Arkansas, Georgia, Kentucky, Louisiana, New York, and Virginia, with storms also affecting other states in the Southern and Eastern United States. In total, 360 tornadoes were confirmed by NOAA's National Weather Service (NWS) and Government of Canada's Environment Canada in 21 states from Texas to New York to southern Canada. Widespread and destructive tornadoes occurred on each day of the outbreak. April 27 was the most active day, with a record 216 tornadoes touching down that day from midnight to midnight CDT. Four of the tornadoes were rated EF5, which is the highest ranking on the Enhanced Fujita scale; typically these tornadoes are recorded no more than once a year.
From May 21 to May 26, 2011, one of the largest tornado outbreaks on record affected the Midwestern and Southern regions of the United States. A six-day tornado outbreak sequence, most of the tornadoes developed in a corridor from Lake Superior southwest to central Texas, while isolated tornadoes occurred in other areas. An especially destructive EF5 tornado destroyed one-third of Joplin, Missouri, resulting in 158 deaths and over 1,000 injuries. The Joplin tornado was the deadliest in the United States since April 9, 1947, when an intense tornado killed 181 in the Woodward, Oklahoma, area. Tornado-related deaths also occurred in Arkansas, Kansas, Minnesota, and Oklahoma. Overall, the tornado outbreak resulted in 186 deaths, 8 of those non-tornadic, making it second only to the 2011 Super Outbreak as the deadliest since 1974. It was the second costliest tornado outbreak in United States history behind that same April 2011 outbreak, with insured damage estimated at $4–7 billion.
The 2011 Joplin tornado was a large and devastating multiple-vortex tornado that struck Joplin, Missouri, United States, on the evening of Sunday, May 22, 2011. Part of a larger late-May tornado outbreak, the EF5 tornado began just west of Joplin and intensified very quickly, reaching a maximum width of nearly one mile (1.6 km) during its path through the southern part of the city. The tornado tracked eastward through Joplin, and then continued across Interstate 44 into rural portions of Jasper and Newton counties, weakening before it dissipated.
The 2012 Leap Day tornado outbreak was a significant and deadly tornado outbreak on February 28 and February 29, 2012, leap day. It caused severe damage in several regions, especially the Great Plains and Ohio Valley regions. It also resulted in several tornadoes in the Central Plains, a rarity for the time of year. The most destructive and deadly tornado was a violent early-morning EF4 that hit Harrisburg, Illinois, killing 8 people. In total, 15 people died in the outbreak. Just two days later, a larger and deadlier outbreak devastated the Ohio Valley and Southern United States.
This page documents the tornadoes and tornado outbreaks of 2013. Strong and 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 2004 Myanmar cyclone was considered the worst to strike the country since 1968. The second tropical cyclone of the 2004 North Indian Ocean cyclone season, it formed as a depression on May 16 in the central Bay of Bengal. With low wind shear and a surge in the monsoon trough, the storm intensified while meandering over open waters. The storm eventually began a steady northeastward motion due to a ridge to the north over India. While approaching land, an eye developed in the center of the storm, indicative of a strong cyclone. On May 19, the cyclone made landfall along northwestern Myanmar near Sittwe, with maximum sustained winds estimated at 165 km/h (105 mph) by the India Meteorological Department. The storm rapidly weakened over land, although its remnants spread rainfall into northern Thailand and Yunnan province in China.
This page documents notable tornadoes and tornado outbreaks worldwide in 2016. Strong and 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 develop occasionally in southern Canada during the Northern Hemisphere's summer and somewhat regularly at other times of the year across Europe, Asia, and Australia. Tornadic events are often accompanied with other forms of severe weather, including strong thunderstorms, strong winds, and hail. There were 1,059 tornadoes reported in the United States in 2016, of which 974 were confirmed. Worldwide, 133 fatalities were reported: 100 in China, 18 in the United States, five in Uruguay, four in Brazil and two in Italy, Russia and Indonesia each.
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.
On March 31, 2019, a powerful "rainstorm" swept across two districts of southern Nepal killing at least 28 and injuring more than 1,100 people. It was later identified as the first confirmed case of a tornado in Nepal. Lacking advanced technologies to predict or record a tornado, the scientists instead based their findings on forensic evidence, including witness accounts. The government has insisted that technological upgrades are being instituted to improve the country's virtually non-existent weather-warning system.
The 1994 Bangladesh cyclone was a powerful tropical cyclone in the Bay of Bengal. The cyclone closely followed the path, strength, and time of year of a deadly cyclone in 1991 that killed more than 138,000 people. The 1994 cyclone formed on April 29 as a depression, which organized and intensified significantly over the subsequent few days. On May 2, the cyclone attained winds of 215 km/h (135 mph), according to the India Meteorological Department (IMD). That day, the storm made landfall in southeastern Bangladesh, and rapidly weakened over land, before dissipating on May 3.
On the night of 27 January 2019, at 20:20 CST, an unusually violent and destructive tornado ripped through the Cuban capital Havana. The EF4 tornado toppled trees and utility poles, destroyed cars and sent debris flying as it passed through the city. According to the Cuban Institute of Meteorology, the tornado was produced by a cold front that struck the nation's north coast, but "there were no indications of the anticipated existence of any cloud that fulfilled the characteristics of a classic supercell, nor a minisupercell, and that would explain the development of the intense tornado". At least eight people died and more than 190 were injured.
