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. In 2023, tornado expert Thomas P. Grazulis created the outbreak intensity score (OIS) as a way to rank various tornado outbreaks. The 1965 Palm Sunday tornado outbreak received an OIS of 238, making it the fourth worst tornado outbreak in recorded history.
This article lists various tornado records. The most "extreme" tornado in recorded history was the Tri-State tornado, which spread through parts of Missouri, Illinois, and Indiana on March 18, 1925. It is considered an F5 on the Fujita Scale, holds records for longest path length at 219 miles (352 km) and longest duration at about 3+1⁄2 hours, and held the fastest forward speed for a significant tornado at 73 mph (117 km/h) anywhere on Earth until 2021. In addition, it is the deadliest single tornado in United States history with 695 fatalities. It was also the second costliest tornado in history at the time, and when costs are normalized for wealth and inflation, it still ranks third today.
The Bulahdelah Tornado was an intense tornado which occurred near the town of Bulahdelah (100 kilometres north-northeast of Newcastle, New South Wales, Australia on 1 January 1970, and is thought to be the most destructive tornado ever documented in Australia, however, no official rating has been made public.
Severe storms in Australia refers to the storms, including cyclones, which have caused severe damage in Australia.
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.
Tornadoes have been recorded on all continents except Antarctica. They are most common in the middle latitudes where conditions are often favorable for convective storm development. The United States has the most tornadoes of any country, as well as the strongest and most violent tornadoes. A large portion of these tornadoes form in an area of the central United States popularly known as Tornado Alley. Canada experiences the second most tornadoes. Ontario and the prairie provinces see the highest frequency. Other areas of the world that have frequent tornadoes include significant portions of Europe, South Africa, Philippines, Bangladesh, parts of Argentina, Uruguay, and southern and southeastern Brazil, northern Mexico, eastern and western Australia, New Zealand, and far eastern Asia.
A series of destructive severe thunderstorms struck southeastern Queensland, Australia, on 29 November 1992. The storms produced strong winds, flash flooding and large hailstones in the region, including the capital city of Brisbane. The storms also spawned two of the most powerful tornadoes recorded in Australia, including the only Australian tornado to be given an official 'F4' classification on the Fujita scale and the last violent tornado in Australia until 21 March 2013.
The 1984 Soviet Union tornado outbreak, also known as the 1984 Ivanovo tornado outbreak, occurred on June 9, that struck the Ivanovo and Yaroslavl regions north of Moscow, an area over 400,000 km2. At least two of the eleven known tornadoes were violent events, equal to F4 or higher in intensity on the Fujita scale. It was one of only three disastrous tornado outbreaks in modern Russian history, and the third-deadliest tornado outbreak in European history.
This page documents the tornadoes and tornado outbreaks of 1999, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally, particularly in parts of neighboring southern Canada during the Northern Hemisphere's summer season, as well as Europe. One particular event, the Bridge Creek-Moore, Oklahoma F5 tornado, produced the highest wind speed ever recorded on Earth, which was 301 ± 20 mph (484 ± 32 km/h).
Bullyard is a small rural town and locality in Bundaberg Region, Queensland, Australia. In the 2021 census, the locality of Bullyard had a population of 206 people.
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.
This page documents the tornadoes and tornado outbreaks of 1970, 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.
Bucca is a rural locality in the Bundaberg Region, Queensland, Australia. In the 2021 census, Bucca had a population of 1,063 people.
A localized but devastating series of severe thunderstorms affected the Great Lakes region during May 20-21, 1953. The strongest of these storms produced three intense, long-tracked tornadoes in Iowa, Michigan, and Ontario. The worst tornado event was a violent F4 tornado that tore through the cities of Port Huron, Michigan, and Sarnia, Ontario, on May 21, damaging or destroying hundreds of structures and causing dozens of casualties. Overall, the tornadoes killed eight people, injured 123 others, and caused at least $17.6 million (1953 USD) in damage. Thunderstorm winds also caused an additional fatality when a tree fell on a house in Waterloo, Iowa.
The first six days of December 1953 produced a destructive and deadly tornado outbreak sequence across the Southern United States. There were 19 confirmed tornadoes, including a violent F4 tornado that hit the northwest side of Alexandria, Louisiana and even more violent F5 tornado that hit Vicksburg, Mississippi. In all, the tornadoes killed 49 people, injured 404 others, and caused $45,709 million in damage. The death toll made this deadliest December tornado outbreak ever recorded and it would not be surpassed until 2021. This was also the last of the series of deadly and catastrophic tornado outbreaks to strike the US in 1953.
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.
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.
