1Most severe tornado damage; see Fujita scale 2Time from first tornado to last tornado
A large, weeklong tornado outbreak sequence[nb 2] of 73 tornadoes occurred on May 3–9, 1961, impacting areas from Utah to the East Coast of the United States. Overall, the outbreak sequence caused 23 fatalities, 126 injuries, and $42.205 million in damages (1961 USD).
Meteorological synopsis
Multiple weather systems impacted mostly the Great Plains and Midwest, bringing multiple rounds of severe weather and tornadoes throughout the region starting on May 3 and ending on May 9. Other weather systems also produced tornadoes in Florida and Utah.[4][5]
Twin tornadoes formed north of Dougherty after one tornado split into two. This one, which was smaller than the other, hit the town, destroying three trailers and a barn, ripping a porch off a house, and overturning several cotton trailers. Damage was estimated at $25,000.[4][9]
A rare, strong tornado struck Green River, although only mostly minor damage occurred with losses totaling $2,500. This was the second of only 11 F2/EF2+ tornadoes ever recorded in Utah since 1950. Tornado researcher Thomas P. Grazulis did not classify the tornado as an F2 or stronger.[4][13][14][15][16]
A long-lived, large, multi-vortex tornado tracked mainly over open terrain. A few outbuildings, an abandoned house and schoolhouse, utility lines and fences were destroyed and very large hail up to the size of baseballs damaged crops. The tornado hurled cars off a nearby highway as well. Losses from the tornado totaled $25,000.[4][17][18]
This large tornado blew the roofs off of several farmhouses and swept away outbuildings. As it crossed US 271, a boat and trailer were blown off of a moving vehicle and thrown into the field a considerable distance away. Windows were blown out of homes as well. Despite the damage, no monetary damage value was given. Grazulis did not list the tornado as an F2 or stronger.[4][19][16]
A tornado struck the town of Leedey, destroying outbuildings and unroofing two businesses. 1-inch-diameter (2.5 cm) hail also fell east of town. No damage value was given.[4][20][18]
This strong tornado touched down north of the previous one. There was $2,500 in damage. Grazulis did not list the tornado as an F2 or stronger.[4][21][16]
1 death – This was the first of a complex of three tornadoes that formed over a 30-mile-long (48 km) path. More than 20 farmsteads were severely damaged or destroyed both in and around Geary, including one demolished building where a person was killed. The tornado, which caused $25,000 in damage, may have been up to 800 yards (730 m) wide.[4][22][18]
This was the second of a complex of three tornadoes that formed over a 30-mile-long (48 km) path. A schoolhouse was partly unroofed, and a three-story frame home was destroyed. Nearby farmsteads were also severely damaged or destroyed. The tornado, which caused $25,000 in damage, may have been up to 800 yards (730 m) wide.[4][23][18]

This strong tornado touched down on the Johnny Bravo ranch in rural Pecos County well southeast of Fort Stockton, demolishing the ranch's headquarters, several barns and outbuildings, and three trucks, killing several horses and injuring one (although the injury was not officially counted). It supposedly lifted before touching down again on the Ligon ranch, destroying the ranch house, a windmill, and several outbuildings. Damage was estimated at $250,000. Storm Data list the tornado as happening on May 3 rather than May 4. Grazulis classified the tornado as an F2.[4][25][18]
This tornado damaged several farmsteads and 2-inch-diameter (5.1 cm) hail damaged 70 windows in Piedmont. Losses from the tornado totaled $2,500.[4][26]
A brief, but strong tornado destroyed outbuildings and uprooted trees on a farm, causing $2,500 in damage. Witnesses in Arnett saw the funnel from the tornado southwest of town. Grazulis did not list the tornado as an F2 or stronger.[4][27][16]
A weak, narrow tornado damaged mesquites on the old Metador ranch, causing no monetary damages. Storm Data list the tornado as happening on May 3 rather than May 4.[4][29]
May 5 event
List of confirmed tornadoes – Friday, May 5, 1961[nb 3][nb 4]
16 deaths – This violent, catastrophic tornado first touched down southeast of Talihina, where an outbuilding on a farmstead was destroyed. It then moved through 12 miles (19 km) of forest in rural areas as it crossed over the Winding Stair Mountains, although there is a possibility that the tornado lifted, and a new tornado formed. As it came down Brushy Mountain, it became violent and struck Reichert, obliterating almost everything in its path. It then crossed the Yellow Spring Ridge and Potts Mountain and moved through both Glendale and Howe, completely destroying more buildings and homes before dissipating. In all, at least 70 homes were damaged or destroyed. It caused the most casualties during the outbreak, with 16 deaths and 58 injuries, along with $250,000 in damage.[4][33][18]
This brief but intense tornado unroofed two large buildings and uprooted many large trees, causing $25,000 in damage. The funnel cloud of the tornado was spotted on the northwest side of town before it touched down. Grazulis did not list the tornado as an F2 or stronger.[4][34][16]

List of confirmed tornadoes – Sunday, May 7, 1961[nb 3][nb 4]
3 deaths – A tornado formed on the south side of Bruno and passed east of town as it meandered northeast. It moved over rugged, rural terrain for a while before growing tremendously as it approached Yellville. It intensified before crossing over Crooked Creek into the western side of the town, causing major damage to the area. It then reached its maximum width as it tore through Summit at F3 intensity, inflicting widespread extensive damage to homes, buildings, and trees. All the casualties from the storm occurred here. Timber along the path was also damaged by the tornado. After moving out of Summit, the tornado quickly narrowed and weakened and dissipated in a rural area north of town. It all, the tornado destroyed 30 buildings and damaged 50 others along its path. Three people were killed, nine (possibly 12) others were injured, and losses totaled $2.5 million in damage. Heavy rainfall from the storm also damaged crops and roadways as well.[4][54][37]
A skipping tornado developed west of the Faulkner school and moved northeastward, damaging buildings on several farms each time it touched down. Losses totaled $25,000. Grazulis did not list the tornado as an F2 or stronger.[4][55][16]

This violent, multi-vortex tornado first touched down north-northwest of Basehor, Kansas on the south side of Fairmount. It moved east-northeast and quickly intensified as neared the Missouri River, turning east-southeast and then east north of Wolcott. About 40-50 homes were damaged and a car was thrown 300 feet (91 m) over a 50 feet (15 m) grove of trees before landing upside down on railroad tracks, injuring the three women inside. Nine other injuries occurred over this part of the track as well. The tornado then crossed the Missouri River into Missouri, striking the town Waldron before striking Weatherby Lake and Barry, where more damage occurred. The tornado continued to cause damage as it moved through the extreme northern part Kansas City as well as the north side of Liberty before dissipating.

Storm Data also list the tornado as having occurred on May 8 rather than May 9.[4][103]
A strong tornado skipped east-northeast, heavily damaging multiple vacation resorts in five or six areas, including three of them that were almost completely destroyed. The tornado dissipated over the Neversink Reservoir southwest of Neversink. The tornado caused $2.5 million in damage, and damaged 50 structures, and four (possibly only three) people suffered minor injuries, which were mainly from shock.[4][104][37]
A westward-moving waterspout crossing over Tampa Bay made landfall on the north side of St. Petersburg, causing severe damage to multiple buildings. Two homes were unroofed, including one where the TV antenna was bent and dropped on a car. A high school was also unroofed before the tornado dissipated after tracking only .5 miles (0.80 km) with a maximum width of 50 yards (46 m). Although there were no casualties, the tornado left behind $25,000 in damage.[4][31][32]
A large, long-tracked F3 tornado–which was likely a tornado family–first touched down on the north shore of Witmer Lake in LaGrange County, Indiana. It moved due east and immediately became strong as it moved into Witmer Manor and Webers Landing. A total of 22 cottages were destroyed or badly damaged while 30 others sustained minor damage. All five injuries from the tornado occurred here before the tornado passed north of Wolcottville. From there, the tornado weakened and skipped along a non-continuous damage path. Scores of homes and barns were damaged as the tornado passed over Blackman Lake, Northern South Milford, Woodland Park, Big Long Lake, Shady Nook, Gravel Beach, Timberhurst, and Taylor Lake. Damages in LaGrange County totaled $2.5 million.
The tornado then crossed into Steuben County, continuing to skip and damage homes and barns as it moved through Turkey Creek and passed north of Hudson and Ashley. As it approached Forest Park north of Hamilton it touched down solidly again and intensified. It then struck Forest Park before crossing Hamilton Lake and striking Oakwood and Circle Park. Two cottages were destroyed, several more were unroofed, and a car with four occupants was thrown in Hamilton Lake, although none of these events resulted in any casualties. It then moved back into rural areas before crossing into Ohio. Damages in Steuben County reached $2.5 million.
In Williams County, Ohio, the tornado turned northeastward, passing through the northwest side of Edon. Damage here was severe as multiple farmhouses and barns were demolished or extensively damaged. After passing Edon, the tornado quickly weakened and dissipated. Losses in Ohio totaled $25,000.
The tornado was on the ground for at least 38 minutes, traveled 33.4 miles (53.8 km), was 800 yards (730 m) and caused $5.025 million in damage. Five people were injured.[4][45][46][47]
Hand Valley–Clarkridge, Arkansas/Udall–South Fork, Missouri
Hand Valley–Clarkridge, Arkansas/Udall–South Fork, Missouri
This slow-moving, long-tracked, large, multi-vortex F3 tornado first touched down in Hand Valley, Arkansas and moved northeastward over the Crooked Creek and White River. It then passed east of Gassville before moving into Colfax, causing heavy damage. It did more damage as it passed through the west side of Mountain Home before moving back into rural areas. It crossed over Walker Creek, Pigeon Creek, and East Pigeon Creek, before reaching its peak intensity as it tore into Clarkridge. A church, a store, and two homes were destroyed before the tornado moved into Missouri. Throughout Arkansas, the tornado damaged 50 other buildings, injured one, and caused $2.5 million in damage.
The tornado then moved into Missouri and turned northeastward, heavily damaging multiple farm homes and buildings as it crossed over the Norfolk Lake and passed through the south side of Udall. It then moved through mostly rural areas before striking Egypt Grove and Hocomo, causing additional heavy damage, although it was beginning to weaken by this time. The tornado caused some additional damage before dissipating just within the city limits of South Fork. Throughout Missouri, nine people were injured, and damage was estimated at $1 million.
The tornado was on the ground for a least an hour and 15 minutes, tracked 43.8 miles (70.5 km), was 333 yards (304 m) wide, and caused $3.5 million in damage. A total of 10 people were injured. One source list the tornado as being much larger than officially documented with a peak width of 3,000–3,520 yards (2,740–3,220 m) (or 2 miles (3.2 km)) wide. Rainfall from the storm also damaged field crops in Arkansas.[4][57][58][59][60][61]
This long-tracked, large F3 tornado touched down just west of Madisonville and immediately reached its peak intensity as it moved east-northeast into downtown. Multiple buildings and homes were extensively damaged, including a three-story brick building that lost its top two floors and two two-story brick buildings that had extensive damage. Trees and power lines were downed, an airplane was destroyed at the Madisonville Municipal Airport in nearby Anton, and cars were damaged by flying debris. All three injuries from this tornado occurred near or in town and losses totaled $2.5 million alone. From Madisonville, the tornado weakened and turned eastward, causing lesser, but still considerable damage as it hit Northern Millport as well as the towns of Bremen Station and Bremen. From there, it began to skip as it hit the town of Moorman, unroofing the Moorman High School gym and destroying a small home. Damage was also observed in Centertown, Beaver Dam, Mt. Pleasant, Arnold, Dogwalk, and Neafus before the tornado finally dissipating in Peth.
The tornado was on the ground for an hour and five minutes, tracked 58 miles (93 km), and was 880 yards (800 m) (one source says 1,320 yards (1,210 m)) wide. Three people were injured, and losses totaled $15 million. Despite the heavy damage, tornado researcher Thomas P. Grazulis gave the tornado an F2 rating. It is also possible that the tornado started in McLean County while never crossing into Grayson County.[66][67][68][69][70][71]
Non-tornadic impacts
Numerous reports of large hail and wind damage were confirmed throughout the event.[1] The biggest hailstone was recorded as being 3 inches (7.6 cm) in diameter and was recorded twice in both Texas and Oklahoma as well as once in Kansas.[105] On May 6, the strongest winds were recorded in Tupelo, Mississippi, where 105 mph (169 km/h) gusts destroyed a plane and damaged several others at an airport.[4][106] On May 5, severe thunderstorm winds in Nebraska City, Nebraska destroyed an airplane hangar and tossed the plane inside into the trees nearby.[4] In addition to the numerous tornadoes that occurred, one waterspout was confirmed to have taken place near Key West, Florida on May 9.[4] Heavy snow of up to 8 inches (20 cm) fell west of the Continental Divide in Montana with Missoula setting a record for the most snow seen in a 24-hour period with 6.5 inches (17 cm).[4]
2021 Western Kentucky tornado – A long-tracked EF4 tornado that affected areas struck by tornadoes in this outbreak sequence
Notes
^One hailstone reportedly reached 9.99 inches (25.4 cm) in diameter in Indiana, but this is more likely an error in the system.
^An outbreak is generally defined as a group of at least six tornadoes (the number sometimes varies slightly according to local climatology) with no more than a six-hour gap between individual tornadoes. An outbreak sequence, prior to (after) the start of modern records in 1950, is defined as a period of no more than two (one) consecutive days without at least one significant (F2 or stronger) tornado.[3]
