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.

From May 4–6, 2007, a major and damaging tornado outbreak significantly affected portions of the Central United States. The most destructive tornado in the outbreak occurred on the evening of May 4 in western Kansas, where about 95% of the city of Greensburg in Kiowa County was destroyed by an EF5 tornado, the first of the new Enhanced Fujita Scale and such intensity since the 1999 Bridge Creek–Moore tornado. The supercell killed 13 people, including 11 in Greensburg and two from separate tornadoes. At least 60 people were injured in Greensburg alone. It was the strongest tornado of an outbreak which included several other tornadoes reported across Oklahoma, Colorado, Kansas and South Dakota that occurred on the same night.

Although one of the most damaging tornadoes of the outbreak sequence occurred in Greensburg on May 4, 25 tornadoes were confirmed that day. That number exploded to 92 the following day (May 5), with many tornadoes near the affected area from the previous night. Most were in open country, but there were injuries in at least two spots in Kansas, and one death reported near a county lake in Ottawa County. Fifteen more tornadoes were confirmed on May 6 in the region before the outbreak finally ended. (Full article...)

Tracks of all US tornadoes in 1984.

This page documents the tornadoes and tornado outbreaks of 1984, 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...)

2024 tornado activity

The storm system responsible for the outbreak and derecho, as seen on April 2

From April 1 to 3, 2024, a significant tornado outbreak, which also included a derecho, affected much of the Midwestern and Southeastern United States. The National Weather Service issued dozens of severe thunderstorm and tornado warnings across West Virginia, Kentucky, Tennessee, Ohio, Oklahoma, Kansas, Illinois, Indiana, and Missouri during the event. A total of 32 million people were estimated to be under watches or warnings, and over 150,000 people were estimated to be without power. and 15 people were injured. The event was given an outbreak intensity score of 28 points, ranking it as a significant tornado outbreak, and five people were killed by non-tornadic events as well. (Full article...)

A cumulative map of all tornadoes and tornado warnings throughout the outbreak

Accompanying Hurricane Katrina's catastrophic coastal impacts was a moderate tornado outbreak spawned by the cyclone's outer bands. The event spanned August 26–31, 2005, with 57 tornadoes touching down across 8 states. One person died and numerous communities suffered damage of varying degrees from central Mississippi to Pennsylvania, with Georgia sustaining record monetary damage for the month of August. Due to extreme devastation in coastal areas of Louisiana and Mississippi, multiple tornadoes may have been overlooked—overshadowed by the effects of storm surge and large-scale wind—and thus the full extent of the hurricane's tornado outbreak is uncertain. Furthermore, an indeterminate number of waterspouts likely formed throughout the life cycle of Hurricane Katrina.

The outbreak began with an isolated F2 over the Florida Keys on August 26; no tornadoes were recorded the following day as the storm traversed the Gulf of Mexico. Four weak tornadoes were observed on August 28 as the hurricane approached land, each causing little damage. Coincident with Katrina's landfall, activity began in earnest on August 29 with numerous tornadoes touching down across Gulf Coast states. Georgia suffered the greatest impact on this day, with multiple F1 and F2 tornadoes causing significant damage; one person died in Carroll County, marking the first known instance of a tornado-related death in the state during August. A record 18 tornadoes touched down across Georgia on August 29, far exceeding the previous daily record of just 2 tornadoes for the month throughout the state. Activity diminished over the subsequent two days as the former hurricane moved northward. Several more tornadoes touched down across the Mid-Atlantic states before the cessation of the outbreak just after midnight local time on August 31. (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!
