The 2011 Super Outbreak was the largest, costliest, and one of the deadliest tornado outbreaks ever recorded, taking place in the Southern, Midwestern, and Northeastern United States from April 25 to 28, 2011, leaving catastrophic destruction in its wake. Over 175 tornadoes struck Alabama, Mississippi, and Tennessee, which were the most severely damaged states. Other destructive tornadoes occurred in Arkansas, Georgia, Kentucky, Louisiana, New York, and Virginia, with storms also affecting other states in the Southern and Eastern United States. In total, 360 tornadoes were confirmed by NOAA's National Weather Service (NWS) and Government of Canada's Environment Canada in 21 states from Texas to New York to southern Canada. Widespread and destructive tornadoes occurred on each day of the outbreak. April 27 was the most active day, with a record 216 tornadoes touching down that day from midnight to midnight CDT (05:00–05:00 UTC). Four of the tornadoes were rated EF5, which is the highest ranking on the Enhanced Fujita scale; typically these tornadoes are recorded no more than once a year.
In total, 348 people were killed as a result of the outbreak, including 324 tornado-related deaths across six states and 24 fatalities caused by other thunderstorm-related events such as straight-line winds, hail, flash flooding or lightning. In Alabama alone, 238 tornado-related deaths were confirmed by the Storm Prediction Center (SPC) and the state's Emergency Management Agency. April 27's 316 fatalities were the most tornado-related fatalities in the United States in a single day since the "Tri-State" outbreak on March 18, 1925 (when at least 751 people were killed). Nearly 500 preliminary local storm reports were received for tornadoes over four days, including 292 in 16 states on April 27 alone. This event was the costliest tornado outbreak in United States history, with total damage reaching $10.2 billion (equivalent to $14 billion in 2023). In 2023, tornado expert Thomas P. Grazulis created the outbreak intensity score (OIS) as a way to rank various tornado outbreaks. The 2011 Super Outbreak received an OIS of 378, making it the second most intense tornado outbreak in recorded history behind only the 1974 Super Outbreak. (Full article...)Selected tornado list -
This is a list of the deadliest tornadoes in world history. This list includes confirmed individual tornadoes that caused 100 or more direct fatalities.
The deadliest tornadoes by far have occurred in a small area of Bangladesh and East India. In this 8,000-square-mile (21,000 km2) area, 24 of the 42 tornadoes which are known to have killed 100 or more people occurred. This is probably due to the high population density and poor economic status of the area, as well as a lack of early warning system. (Full article...)Selected image -
Selected tornado year -
This page documents the tornadoes and tornado outbreaks of 1967, 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.

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...)List of Featured articles and lists
