A tornado near Anadarko, Oklahoma, in 1999Tornadoes 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 Edmonton tornado of 1987, an event also known as Black Friday to Edmontonians, was a powerful and devastating tornado that ripped through the eastern parts of Edmonton, Alberta, Canada and parts of neighbouring Strathcona County on the afternoon of Friday, July 31, 1987. It was one of seven other tornadoes in central Alberta the same day.
The tornado peaked at F4 on the Fujita scale and remained on the ground for an hour, cutting a swath of destruction 30.8 km (19.1 mi) in length and up to 1.3 km (0.81 mi) wide in some places. It killed 27 people, and injured more than 300, destroyed more than 300 homes, and caused more than C$332.27 million (equivalent to $762 million in 2023) in property damage at four major disaster sites. The loss of life, injuries and destruction of property made it the worst natural disaster in Alberta's recent history and the second deadliest in Canada's history, after the Regina Cyclone.

This page documents the tornadoes and tornado outbreaks of 1996, 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, however by the 1990s tornado statistics were coming closer to the numbers we see today.

Although historically the U.S.stateofConnecticut 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...)
