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 February 28 – March 2, 2007 was a deadly tornado outbreak across the southern United States that began in Kansas on February 28, 2007. The severe weather spread eastward on March 1 and left a deadly mark across the southern US, particularly in Alabama and Georgia. Twenty deaths were reported; one in Missouri, nine in Georgia, and 10 in Alabama. Scattered severe weather was also reported in North Carolina on March 2, producing the final tornado of the outbreak before the storms moved offshore into the Atlantic Ocean.

In the end, there were 57 tornadoes confirmed during the outbreak, including three EF3 tornadoes reported across three states, as well as three EF4 tornadoes; two in Alabama and one in Kansas, the first such tornadoes since the introduction of the Enhanced Fujita Scale. Total damages were estimated at over $580 million from tornadoes alone, making it the fourth-costliest tornado outbreak in US history (the figure not including damage from other thunderstorm impacts including hail and straight-line winds). Insured losses in the state of Georgia topped $210 million, making this outbreak the costliest in that state's history. Enterprise, Alabama, which was hit the hardest, sustained damages in excess of $307 million. ( Full article...)

Map of all recorded tornadoes in the United States during 1982
This page documents the tornadoes and tornado outbreaks of 1982, 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...)

  • 1880 – Much of the western part of Macon, Mississippi was destroyed by an F4 tornado. Twenty-two people, including several entire families, were killed. Railroad equipment and loaded freight cars were thrown up to 100 yards.
  • 1893 – An F4 tornado up to 1.25 miles (2.01 km) wide moved through Newcastle and Moore, Oklahoma, killing 31 people, including 11 in one home. Many homes of light construction were swept away. This was the first of several devastating storms to strike Moore in its long history of major tornadoes.
  • 1929 – The most significant tornado on record in southeastern Georgia killed at least 40 people as it swept away homes in Emanuel, Candler, and Bulloch Counties. The path of the F4 tornado was, at times a mile (1.6 km) wide.

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...)
