Tornadoes are fairly uncommon in the US region of New England. Fewer tornadoes are recorded here than anywhere else east of the Rocky Mountains. [1] However, these deadly and destructive storms do occur; on average, about eight tornadoes are reported in the region each year. Almost 200 people have been killed by these storms in recorded history, and two of the ten most destructive tornadoes in US history occurred in this region.

Tornadoes are a violent weather phenomenon that occur most often in the United States, to the east of the Rocky Mountains. However, they most often occur in the Southern and Central United States, and are comparatively rare in New England. However, no region is immune to tornadoes if the weather conditions are right. [3]
While tornadoes have been recorded in almost every county in New England, there is a region just east of the Berkshires with a much higher concentration of tornado occurrences. This area is analogous to the Tornado Alley of the Great Plains, but on a much smaller scale. [1] [2]
On average (1950–2008), more than two tornadoes per year strike the state of Massachusetts alone, with New England as a whole recording more than 8. [1] [2] Most tornadoes reported in the region are "weak", rated EF0 or EF1 on the Enhanced Fujita scale (the Fujita scale prior to 2007). Around 30% are "significant" tornadoes (rated EF2 or greater), and only 1% are violent (rated EF4 or EF5, the highest damage rating). Weak tornadoes occur in all areas of New England, but EF3 or greater tornadoes have been reported only in New England's practical "Tornado Alley" of Massachusetts, Connecticut, and southern New Hampshire. [2]
Peak tornado activity in New England occurs during the summer months of June, July and August. Tornadoes typically strike between 3 and 9 pm local time, and move at a forward speed of around 30 miles per hour (48 km/h). [4]
There have been 34 killer tornadoes in New England's recorded history: [2] [5]
Only two tornadoes in the history of New England have killed more than 10 people: the 1953 Worcester Tornado and the 1878 Wallingford tornado. The Worcester Tornado killed as many as 94 people in Worcester, Massachusetts, on June 9, 1953, and the Wallingford Tornado killed as many as 34 in Wallingford, Connecticut, on August 8, 1878. These two tornadoes, both estimated to be of F4 intensity on the Fujita scale, killed more people than the rest of the tornadoes in the region's recorded history combined. Since most New England tornadoes are weak and short-lived, it is understandable why tornadoes causing fatalities are a rare occurrence.
Of the costliest tornadoes in US history (adjusted for inflation), two occurred in New England: The 1979 Windsor Locks, Connecticut tornado, which caused $200 million in damage ($840 million in 2024 US$), and the 1953 Worcester tornado, which caused $52 million in damage ($592 million in 2024 US$). [23] The Worcester tornado damaged or destroyed thousands of homes over a wide swath of central Massachusetts; the Windsor Locks tornado by contrast had a relatively small damage path, but it caused significant damage to parts of Bradley International Airport, including the New England Air Museum, where dozens of expensive and historic aircraft were damaged or destroyed, leading to the large damage figure. [24]
On April 10–12, 1965, a historic severe weather event affected the Midwestern and Southeastern United States. The tornado outbreak produced 55 confirmed tornadoes in one day and 16 hours. The worst part of the outbreak occurred during the afternoon hours of April 11 into the overnight hours going into April 12. The second-largest tornado outbreak on record at the time, this deadly series of tornadoes, which became known as the 1965 Palm Sunday tornado outbreak, inflicted a swath of destruction from Cedar County, Iowa, to Cuyahoga County, Ohio, and a swath 450 miles long (724 km) from Kent County, Michigan, to Montgomery County, Indiana. The main part of the outbreak lasted 16 hours and 35 minutes and is among the most intense outbreaks, in terms of tornado strength, ever recorded, including at least four "double/twin funnel" tornadoes. In all, the outbreak killed 266 people, injured 3,662 others, and caused $1.217 billion in damage. In 2023, tornado expert Thomas P. Grazulis created the outbreak intensity score (OIS) as a way to rank various tornado outbreaks. The 1965 Palm Sunday tornado outbreak received an OIS of 238, making it the fourth worst tornado outbreak in recorded history.
An extremely devastating and deadly tornado outbreak sequence impacted the Midwestern and Northeastern United States at the beginning of June 1953. It included two tornadoes that caused at least 90 deaths each—an F5 tornado occurring in Flint, Michigan, on June 8 and an F4 tornado in Worcester, Massachusetts, on June 9. These tornadoes are among the deadliest in United States history and were caused by the same storm system that moved eastward across the nation.
A deadly series of at least 33 tornadoes hit at least 10 different U.S. states on May 9–11, 1953. Tornadoes appeared daily from Minnesota in the north to Texas in the south. The strongest and deadliest tornado was a powerful F5 tornado that struck Waco, Texas on May 11, causing 114 of the 144 deaths in the outbreak. Alongside the 1902 Goliad tornado, it was the deadliest tornado in Texas history and is the 11th deadliest tornado in U.S. history. The tornado's winds demolished more than 600 houses, 1,000 other structures, and over 2,000 vehicles. 597 injuries occurred, and many survivors had to wait more than 14 hours for rescue. The destruction dispelled a myth that the geography of the region spared Waco from tornadoes, and along with other deadly tornadoes in 1953, the Waco disaster was a catalyst for advances in understanding the link between tornadoes and radar-detected hook echoes. It also generated support for improved civil defense systems, the formation of weather radar networks, and improved communications between stakeholders such as meteorologists, local officials, and the public.
The Windsor Locks, Connecticut tornado struck the towns of Windsor, Windsor Locks, and Suffield, Connecticut, and Feeding Hills, Massachusetts, on Wednesday, October 3, 1979. The short-lived but intense tornado struck without warning and caused three deaths and 500 injuries along its 11.3-mile (18.2 km) track. It received a rating of F4 on the Fujita scale, one of only three F4 tornadoes in Connecticut's history.
From May 4–10, 1933, a tornado outbreak sequence produced at least 33 tornadoes. Among them was the Beaty Swamp tornado, a violent F4 that struck shortly after midnight CST on May 11, 1933, in Overton County, Tennessee, killing 35 people, injuring 150 others, and devastating the unincorporated communities of Beaty Swamp and Bethsaida. The storm was the second-deadliest tornado in the history of Middle Tennessee, even though it struck a sparsely populated, rural area. The community of Beaty Swamp ceased to exist and does not appear on any current maps. The only landmark that alludes to the former community is Beaty Swamp Road, which intersects Highway 111 in the northeast corner of Overton County. The severe weather event that generated the tornado also produced others, including long-tracked, intense tornadoes or tornado families that devastated portions of Alabama, South Carolina, and Kentucky, killing a combined total of 76 people.
A violent severe weather outbreak struck the Southeast on April 4–5, 1977. A total of 22 tornadoes touched down with the strongest ones occurring in Mississippi, Alabama, and Georgia. The strongest was a catastrophic F5 tornado that struck the northern Birmingham, Alabama, suburbs during the afternoon of Monday, April 4. In addition to this tornado, several other tornadoes were reported from the same system in the Midwest, Alabama, Georgia, Mississippi and North Carolina. One tornado in Floyd County, Georgia, killed one person, and another fatality was reported east of Birmingham in St. Clair County. In the end, the entire outbreak directly caused 24 deaths and 158 injuries. The storm system also caused the crash of Southern Airways Flight 242, which killed 72 and injured 22.
On April 23–25, 1908, a destructive tornado outbreak affected portions of the Midwestern and Southern United States, including the Great Plains. The outbreak produced at least 31 tornadoes in 13 states, with a total of at least 324 tornado-related deaths. Of these deaths, most were caused by three long-tracked, violent tornadoes—each rated F4 on the Fujita scale and considered to be a tornado family—that occurred on April 24. Most of the deaths were in rural areas, often consisted of African Americans, and consequently may have been undercounted. One of the tornadoes killed 143 people along its path, 73 of them in the U.S. state of Mississippi, making the tornado the third deadliest in Mississippi history, following the 1936 Tupelo F5, with 216 deaths, and the 1840 Natchez tornado, with 317 deaths.
On Monday, April 8, 1957, a widespread tornado outbreak struck the Southeastern United States, particularly the Carolinas, and was responsible for seven deaths and 203 injuries across the region. Most of the activity occurred on either side of the Piedmont, including portions of the Cumberland Plateau. At least 18 tornadoes occurred, including several long-tracked tornado families, one of which included a violent tornado that was retrospectively rated F4 on the Fujita scale. Besides tornadoes, the outbreak also generated other severe weather phenomena such as large hail.
On March 16–17, 1942, a deadly late-winter tornado outbreak struck a large area of the Central and Southern United States, killing 149 people and injuring at least 1,312. At least five states reported violent tornadoes, from Illinois and Indiana south to Mississippi, beginning with an F4 tornado in the morning in Illinois. Intense activity spread south to the Gulf Coast and north to the Michigan–Indiana border as the day went on. Seven violent tornadoes were reported, one of which was a powerful F5 in Illinois. A long-tracked F4 tornado family in Mississippi claimed 63 lives as well, becoming the deadliest event of the outbreak. Another long-lived F4 in Tennessee killed 15 more people, and a series of intense tornadoes caused 24 other deaths in Kentucky. The outbreak also produced 18 tornadoes that caused at least one death—ranking eighth on a list of similar events since 1880 by tornado researcher Thomas P. Grazulis.
The Wallingford Tornado was a violent tornado that struck the town of Wallingford, Connecticut, on Friday, August 9, 1878. The tornado, unofficially rated F4 by tornado expert Thomas P. Grazulis, destroyed most of the town, killing about 34 people—estimated totals varied—and injuring at least 70, many severely. This was the deadliest tornado ever to strike the state of Connecticut, and the second deadliest ever in New England, after the Worcester tornado of 1953.
The Four-State Tornado Swarm was a destructive outbreak of tornadoes in New England on August 15, 1787. At least five separate tornadoes caused major damage in the states of Connecticut, Rhode Island, Massachusetts, and New Hampshire. Two people were killed by a tornado in Wethersfield, Connecticut, and many were injured throughout New England. This event is considered to be the first true tornado outbreak on record.
The 1953 Worcester tornado was an extremely powerful and destructive tornado that struck the city of Worcester, Massachusetts and surrounding areas on Tuesday, June 9, 1953, the final day of the Flint–Worcester tornado outbreak sequence. It stayed on the ground for 48 miles (77 km) and 78 minutes. The tornado injured 1,288 people and killed 94, making it one of the deadliest tornadoes in U.S. history and the deadliest tornado to ever strike New England. A total of 4,000 buildings were damaged or destroyed and, per National Weather Service estimates, 10,000 people were left homeless. The tornado caused $52.193 million which, at the time, was the costliest tornado ever recorded.
On April 19–21, 1920, a multi-day severe weather event affected the Southeastern United States. The most intense portion of the outbreak occurred on the morning of April 20. At least seven tornadoes affected the American U.S. states of Mississippi, Alabama, and Tennessee, six of them rated violent F4s on the Fujita scale. The tornado outbreak killed at least 243 people.
The March 1875 Southeast tornado outbreak was a deadly tornado outbreak that affected portions of the Southern United States from March 19–20, 1875. At least 19 tornadoes were recorded, including seven that were destructive enough to be rated F4 by Thomas P. Grazulis. The worst damage and most of the deaths occurred in Georgia. Most of the damage appears to have been the result of two tornado families that moved along parallel paths 12 to 15 mi apart through parts of Georgia and South Carolina. These families each consisted of numerous long-tracked, intense tornadoes. The deadliest tornado of the outbreak was an estimated F4 that killed 28–42 people in and near Sparta, Georgia, and Edgefield, South Carolina, on March 20. A separate F4 that followed a similar trajectory may have killed as many as 30. In all, this outbreak killed at least 96 people, injured at least 377, and caused at least $650,000 in losses.
This page documents notable tornadoes and tornado outbreaks worldwide in 1973, but mostly features events in the United States. According to tornado researcher Thomas P. Grazulis, documentation of tornadoes outside the United States was historically less exhaustive, owing to the lack of monitors in many nations and, in some cases, to internal political controls on public information. Most countries only recorded tornadoes that produced severe damage or loss of life. Consequently, available documentation in 1973 mainly covered the United States. On average, most recorded tornadoes, including the vast majority of significant—F2 or stronger—tornadoes, form in the U.S., although as many as 500 may take place internationally. Some locations, like Bangladesh, are as prone to violent tornadoes as the U.S., meaning F4 or greater events on the Fujita scale.
On April 18–20, 1880, a tornado outbreak impacted the Midwestern United States, producing numerous strong tornadoes, killing at least 166 people, and injuring more than 516 others. The outbreak generated five violent tornadoes, including three long-tracked F4 tornadoes in Missouri that killed at least 144 people. Two of the tornadoes followed parallel paths and occurred simultaneously near Springfield, one of which devastated the town of Marshfield, causing 92 fatalities there. Other deadly, intense tornadoes occurred in the Great Lakes region and in Arkansas, including another F4 tornado that destroyed a third of El Paso, Arkansas, killing four or more people.
Several destructive tornadoes struck the Southeastern United States, primarily along and east of the Lower Mississippi Valley, on February 13, 1952. Multiple intense tornadoes touched down throughout the day, three of which were killers. The deadliest and most destructive tornado of the outbreak was a violent F4 that touched down in south-central Tennessee, killing three people and injuring 44 others. A similarly destructive tornado—albeit of weaker, F2 intensity—formed from the same storm as the preceding F4 and became the second costliest of the outbreak. Another intense tornado affected the Mississippi embayment near Manila, Arkansas, injuring five people, and a pair of deadly F3s in Alabama claimed a combined two lives. In all, the outbreak killed five people and injured 102 others.
This page documents the tornadoes and tornado outbreaks of 1946, primarily in the United States. Most recorded 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.
