Tornadoes are violently rotating columns of air that are in contact with the Earth and either a cumulonimbus or a cumulus cloud. Tornadoes are often referred to as twisters, whirlwinds, or cyclones. While most tornadoes attain winds of less than 110 miles per hour (180 km/h), are about 250 feet (80 m) across, and travel a few miles (several kilometers), the wind speeds in the most intense tornadoes can reach 300 miles per hour (480 km/h), are more than two miles (3 km) in diameter, and stay on the ground for dozens of miles (more than 100 km). Various types of tornadoes include the multiple vortex tornado, landspout, and waterspout. Other tornado-like phenomena that exist in nature include the gustnado, dust devil, fire whirl, and steam devil. Most tornadoes occur in North America (in the United States and Canada), concentrated in a region nicknamed the Tornado Alley. Tornadoes also occur in South America, South Africa, Europe, Asia, and Oceania.
The tornado outbreak of October 17–19, 2007 was a widespread tornado outbreak that took place across much of the eastern half of North America starting on October 17, 2007, and continuing into the early hours of October 19. The outbreak was also responsible for five deaths; three in Michigan and two in Missouri, plus many injuries (including some from non-tornadic events). At least 64 tornadoes were confirmed including 16 on October 17 across six states including Texas, Oklahoma, Arkansas, Louisiana, Mississippi and Missouri with wind damage reported in Oklahoma, Kansas, Illinois, Iowa, Arkansas and Mississippi. On October 18, at least 48 tornadoes were confirmed across eight states including Florida, Alabama, Mississippi, Tennessee, Kentucky, Illinois, Indiana and Michigan, plus widespread straight line wind damage. Until 2010, this event held the record for largest tornado outbreak ever recorded in the month of October according to NOAA. (Full article...)

This page documents the tornadoes and tornado outbreaks of 1985, 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. (Full article...)
A significant tornado outbreak, along with a derecho, affected much of the Midwestern and Southeastern United States from April 1 to 3, 2024. The National Weather Service issued dozens of severe thunderstorm and tornado warnings across those regions during the event. The outbreak first began over portions of the Great Plains and Midwest on April 1, with widespread large hail and damaging winds and a few tornadoes being reported. The outbreak then spread to the Midwest and Ohio Valley on April 2, where the derecho occurred. This was followed by supercell development later in the afternoon. Severe storms also affected parts of the Mid-Atlantic on April 3 as well. A total of 32 million people were estimated to be under watches or warnings, and over 700,000 people were estimated to be without power. Twenty-five people were injured; and five people were killed, all of them by non-tornadic events; three of which happened when downed trees fell onto vehicles in Pennsylvania and New York. The storm system was also responsible for causing flooding in parts of the Northeast, and heavy snow over parts of the Midwest and Northern New England.
The Storm Prediction Center first outlined on April 1 an enhanced risk in areas from north Texas to eastern Illinois, encompassing much of the central United States. In the afternoon hours of the same day, supercell thunderstorms began to develop across northern Texas, moving northeastward and producing large hail. As the event progressed, many tornadic supercells produced brief and weak tornadoes along with high wind gusts; a gust of 90 mph (140 km/h) was recorded in West Virginia, classifying the squall line as a derecho.
The National Weather Service declared the tornado outbreak "historic", stating that not only did it set a daily record for West Virginia, but also broke the yearly record, in one day. Ten tornadoes occurred in West Virginia; which also set a state record for the most tornadoes confirmed in a single day. The previous record was seven; set on both April 4, 1974 and June 2, 1998.

On the evening of March 31, 2023, a tornado struck the Apollo Theatre in Belvidere, Illinois, United States, which caused the ceiling of the theater to suffer a critical structural failure and collapse onto a sold-out concert. The show, headlined by the death metal band Morbid Angel, began despite advance knowledge of expected and imminent severe weather. After a half-hour storm break was instituted during the opening performance of the band Crypta, the tornado struck the theater. Winds of 90–100 miles per hour (140–160 km/h) caused the failure of the lower roof structure, with large amounts of debris falling into the venue, primarily onto concertgoers. Multiple people were buried by debris caused by the collapse. Concertgoers aided in removing debris from on top of others, before the arrival of the Belvidere Fire Department, who evacuated the building and handled search and rescue operations alongside emergency management agencies from three neighboring counties. One concertgoer was pronounced dead at the scene and 27 were taken to hospitals by ambulance, out of 48 that suffered non-fatal injuries.
The venue had been selected for the concert in November of the previous year, following the theater's remodeling as a concert venue. Severe weather was expected on the evening of March 31 in what became a historic tornado outbreak, but multiple people remained in the stage area after warnings for imminent severe weather were received. Following the collapse, the lack of safety protocols despite warning became the subject of multiple lawsuits. The Apollo Theatre was condemned the next day, suffering major damage to not only the roof over the stage but also the street-facing facade and the upper roof structure, of which the latter two were found on the street after the tornado. The venue reopened that September after multiple months of remodeling efforts and a brief fire on the reconstructed roof. (Full article...)
The scope of WikiProject Severe weather is to write articles about severe weather, namely thunderstorms and tornadoes. Their talk page is located here.
WikiProject Weather is the main hub for all articles that are weather-related. WikiProject Weather strives to improve articles in a variety of weather topics, including Tropical Cyclones, Severe Weather, General meteorology, Non-tropical Storms, Climate, Floods, Droughts and wildfires, Meteorological instruments and data, Meteorological Biographies, and Space Weather. If you would like to help, please visit the project talk page.
WikiProject Meteorology is a collaborative effort by dozens of Wikipedians to improve the quality of meteorology- and weather-related articles. If you would like to help, visit the project talk page, and see what needs doing. The project is currently being merged into WikiProject Weather.
WikiProject Tropical cyclones is a daughter project of WikiProject meteorology. The dozens of semi-active members and several full-time members focus on improving Wikipedia's coverage of tropical cyclones.
Wikipedia is a fully collaborative effort by volunteers. So if you see something you think you can improve, be bold and get to editing! We appreciate any help you can provide!
