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 sequence of June 3–11, 2008 was a series of tornado outbreaks affecting most of central and eastern North America from June 3–11, 2008. 192 tornadoes were confirmed, along with widespread straight–line wind wind damage. Seven people were killed from a direct result of tornadoes; four in Iowa, two in Kansas, and one in Indiana. Eleven additional people were killed across five states by other weather events including lightning, flash flooding, and straight-line winds. Severe flooding was also reported in much of Indiana, Wisconsin, Minnesota and Iowa as a result of the same thunderstorms, while high heat and humidity affected much of eastern North America; particularly along the eastern seaboard of the United States from New York City to the Carolinas.

This page documents all tornadoes confirmed by various weather forecast offices of the National Weather Service in the United States during November to December 2018. Based on the 1991–2010 averaging period, 58 tornadoes occur across the United States throughout November while 24 more occur in December.

November saw multiple large outbreaks, the first of which was an extension of an outbreak that began at the end of October while the last one extended into December. December also featured an unusually strong tornado in the state of Washington. November and December finished significantly above average with 88 and 66 tornadoes respectively. However, both months did not have any violent tornadoes, leaving the United States without any tornadoes of such intensity for all of 2018. (Full article...)

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.

There were 1,395 tornadoes reported in the United States in 2003, of which 1,374 were confirmed. 2003 is currently the seventh-most active year for tornadoes in the United States since reliable record-keeping began in 1950. (Full article...)

2024 tornado activity

Map of tornado warnings and confirmed tornadoes from the outbreak

From April 26–28, 2024, a very large, deadly and destructive tornado outbreak occurred across the Midwestern, Southern, and High Plains regions of the United States, primarily on April 26 and 27. The Storm Prediction Center (SPC) first issued an enhanced risk for the Plains on April 26, as a broad upper-trough moved eastwards, with tornadic activity erupted in the states of Iowa and Kansas that evening. A moderate risk was issued by the SPC on April 27 for areas further south in Oklahoma, where a deadly nocturnal event unfolded with many supercell thunderstorms and tornadoes tracking over towns multiple times. Millions were put under a particularly dangerous situation (PDS) tornado watch on April 27, and several PDS tornado warnings were issued that night as strong tornadoes touched down. The outbreak served as the beginning of a broader 16-day period of constant severe weather and tornado activity across the United States that would continue until May 10.

Damaging tornadoes occurred across many states over the two days of the outbreak. On April 26, a tornado in Lancaster County, Nebraska, injured three people, which touched down in the northeastern outskirts of Lincoln, Nebraska. At least six fatalities were attributed to the tornadoes, with more than 156 people injured. At least twenty eight tornadoes were confirmed, with ten in Iowa and one each in Nebraska and Texas. Significant damage was also reported in Elkhorn and near Bennington, Nebraska, from an EF3 wedge tornado that prompted a tornado emergency. Another long-tracked tornado in Iowa that impacted Shelby County, Iowa, prompted two tornado emergencies as well. On April 27, several tornadoes occurred in Texas, Oklahoma, and Kansas. Overnight, a significant tornado passed near Holdenville, Oklahoma, causing at least two fatalities and four injuries. A tornado impacted Sulphur, Oklahoma, as well, causing at least 30 injuries.

The outbreak was the largest since a similarly large and deadly outbreak the year prior, although this one was spread out over a slightly larger time period and was not as deadly. Six people died as a result of this outbreak, and over 150 others were injured. With a grand total of 145 tornadoes over a two-day period, the tornado outbreak gained 87 points on the outbreak intensity score. (Full article...)

Tornado anniversaries

May 22

  • 1987 – A short-lived but devastating F4 tornado destroyed 85% of Saragosa, Texas, killing 30 people, including 22 in building where a Head Start graduation was about to take place. Many of the dead were parents or grandparents who died shielding the children from debris.
  • 2004 – An F4 tornado caused major damage in and near Wilber and Hallam, Nebraska, killing one person and injuring 28. At one point the tornado was 2.5 miles (4.0 km) wide, making it, at the time, the widest tornado ever recorded. This record was later surpassed by the 2.6-mile (4.2 km)-wide 2013 El Reno tornado.
  • 2011 – A catastrophic EF5 tornado devastated the southern portions of Joplin, Missouri, killing 158 people and injuring 1,150. It was the deadliest tornado to hit the United States since 1947 and the costliest in U.S. history with $2.8 billion in damage.

  • 1973 – A highly-visible F4 tornado hit Union City, Oklahoma, killing two people. This was one of the intensely studied tornadoes in scientific history. For the first time, Doppler weather radar detected the circulation of the tornado before it touched down, a significant advancement in tornado forecasting. This was also the first time that scientists had documented the entire life cycle of a tornado in detail.
  • 2011 – An extremely intense EF5 tornado passed near El Reno and Piedmont, Oklahoma, killing nine people and injuring 181. Mobile Doppler radar recorded wind speeds of up to 295 miles per hour (475 km/h). A tanker truck was thrown a mile (1.6 km) and a 1.9-million-pound (860,000 kg) oil rig was rolled three times. Two high-end EF4 tornadoes passed near Blanchard and Washington, Oklahoma. The Blanchard tornado may also have reached EF5 intensity.

Although historically the U.S. state of Connecticut is not typically known to fall casualty to tornadoes, more than 100 of these powerful storms have affected the state in modern history, resulting in at least 48 deaths, 780 injuries, and more than $500 million in damage. This list of tornadoes in the state is likely incomplete, as official records date back only to 1950 for tornadoes in the United States.

As with most of the northeastern United States, the number of tornadoes peaks in the summer months, normally in July or August. Hartford County has had the most tornadoes in the state, although since 1950 Litchfield County has reported the most tornadoes. Several areas have been struck more than once, and Waterbury has been struck by no less than four tornadoes since 1955. (Full article...)
