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{{#tag:ref|The Fujita scale was devised under the aegis of scientist T. Theodore Fujita in the early 1970s. Prior to the advent of the scale in 1971, tornadoes in the United States were officially unrated.{{cite book|last1=Grazulis|first1=Thomas P.|authorlink1=Thomas P.

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 Waco tornado was not the only deadly and damaging tornado in the outbreak sequence. On the same day as the Waco disaster, a high-end F4 tornado struck the Texas city of San Angelo, causing catastrophic damage, killing 13 people, and injuring more than 150. The tornado swept away numerous homes and damaged a school, but students inside escaped without serious injuries. On May 9, a long-tracked F3 tornado destroyed a large swath of Hebron, Nebraska and killed five people in the area. The following day, May 10, featured numerous, often long-tracked and intense tornado families across the states of Iowa, Minnesota, and Wisconsin. Two families on nearly parallel paths traveled more than {{Convert|100|mi}} each and killed a combined total of six people, mostly in Wisconsin. At least one of the tornado families reached F4 intensity in Wisconsin. Two other F4 tornadoes also struck Iowa. Additionally, a relatively moderate tornado of F2 intensity caused significant loss of life in a shack in Minnesota, killing six people. Although 33 tornadoes were officially registered from May 9–11, others likely occurred but either went undetected or were not officially documented.
Background
After two days of intense tornado activity, May 11, 1953, produced a rich, unstable air mass that moved northward over Texas from the Gulf of Mexico. As of 9:30 a.m. CST (15:30 UTC), thunderstorm activity from the overnight hours persisted, generating residual outflow boundaries. Already, anomalously warm surface temperatures reached the mid-70s °F (mid-20s °C) as far north as a line stretching from Dallas to Austin. Dew points were correspondingly high as well, climbing into the lower 70s °F. (lower 20s °C) As a dry line crossed the warm sector in the afternoon, a layer of cool surface temperatures left by the outflow boundaries locally enhanced low-level wind shear, acting as a mechanism to enable supercell and tornado formation. Winds backed along the outflow boundaries, perhaps aiding the formation of large and violent tornadoes.{{cite web|title=Remembering the May 11, 1953, Waco tornado, the deadliest tornado in Texas since 1900 |url=http://www.srh.noaa.gov/fwd/?n=wacotormay1953 |website=National Weather Service Weather Forecast Office Dallas/Fort Worth, TX |publisher=National Weather Service |access-date=19 May 2016 |archive-url=https://web.archive.org/web/20160611024841/http://www.srh.noaa.gov/fwd/?n=wacotormay1953 |archive-date=11 June 2016 |date=6 October 2011 |url-status=live }} Due to conducive conditions for severe weather, the U.S. Weather Bureau (later the National Weather Service) Weather Forecast Office in New Orleans issued a tornado alert covering sections of Central and West Texas.{{cite web|last1=Sawyer |first1=Amanda |url=http://wacohistory.org/items/show/53 |title=Waco Tornado |website=Waco History |publisher=Baylor University |access-date=25 May 2016 |archiveurl=https://web.archive.org/web/20160611020157/http://wacohistory.org/items/show/53 |archivedate=11 June 2016 |url-status=live }}{{cite journal|last1=Coleman|first1=Timothy A.|last2=Knupp|first2=Kevin R.|last3=Spann|first3=James|last4=Elliott|first4=J.

According to Thomas P. Grazulis, the tornado may have entered Nebraska, ending just north of the Kansas–Nebraska border, but its path in Nebraska was overlooked as media mostly covered the Belvidere event. Total losses reached $45,000. One injury may have occurred but was officially unconfirmed. |

After forming west-northwest of San Angelo, the tornado headed east-southeast and struck the north side of the city. There, the tornado caused catastrophic damage to a third of the city. In all, 288 homes were destroyed and about 200 sustained at least some damage. Many of the homes were swept away in a 15-square-block section of the city, and peak damage approached F5 intensity. Additionally, 19 businesses were hit, including the Rocket Drive-In theater, and 172 vehicles were wrecked. The storm struck a school about 15 minutes before students were scheduled for dismissal. The building, which had two stories, lost its roof and many walls, but students sheltered safely in interior hallways, and only 12 were injured, none critically, though the school sustained $100,000 losses (1953 USD). Total contemporary damages reached $3.4 million, and 159 injuries occurred.{{cite web|title=The Lakeview Tornado: May 11, 1953 |url=http://www.srh.noaa.gov/sjt/?n=lakeview_tornado |website=National Weather Service Weather Forecast Office San Angelo, TX |publisher=National Weather Service |access-date=19 May 2016 |archive-url=https://web.archive.org/web/20160611035218/http://www.srh.noaa.gov/sjt/?n=lakeview_tornado |archive-date=11 June 2016 |date=9 May 2013 |url-status=live }} |

This destructive, large and violent, and extremely long-tracked tornado family likely contained at least five distinct tornadoes, spawned by one supercell. The first tornado in the series, though officially unconfirmed, may have formed near Greene in Butler County, Iowa, causing significant destruction on a farmstead. Continuous damage resumed near Chester, severely affecting 11 farms south of the Minnesota–Iowa border, with two injuries in Iowa. The storm then crossed into southern Minnesota, killing one person in a destroyed barn near Wykoff. Near Chatfield, the tornado carried a schoolhouse from its foundation, causing its disintegration. The tornado then hit a few cars halfway between Dover and St. Charles, one of which was carried {{convert|100|ft|m|sigfig=2}}, injuring four occupants and killing the fifth, a child.
In Minnesota, four other people sustained injuries while inside a barn, and three more injuries were in another automobile; in all, 17 injuries were confirmed in the state. Across Fillmore, Olmsted, and Winona counties in Minnesota, over 24 farms received widespread, often severe damage, including the destruction of most buildings in some cases. The tornado downed many power lines and utility poles as well, and there was widespread loss of livestock. Entering Whitewater State Park, the tornado splintered "hundreds" of trees, and buildings in the park were badly damaged. After destroying a steel bridge near Crystal Spring, the tornado apparently dissipated into straight-line winds, though Grazulis suggested that tornado damage may have continued to Cochrane, Wisconsin.
Reports indicated that the storm crossed the Mississippi River into Wisconsin,{{harvnb|Climatological Data|1953|p=135}} where tornado activity definitely resumed northeast of Cochrane and ended near Brownville. As in Minnesota, damage was discontinuous, implying that two or more tornadoes were involved. Between Cochrane and Brownsvulle, the tornado hit roughly 100 farms, at least 20 of which lost buildings, and produced high-end F3 damage to some homes. "Hundreds" of dead livestock littered the landscape. Beyond Brownsville, the tornado(es) likely weakened and reformed into two, perhaps three, others, starting with spotty damage near Gilman. A farmhouse was swept from its foundation, and fragments of the home were lofted for {{Convert|7|mi|spell=in}}. The tornado was reportedly exceptionally large and violent while southeast of Catawba, shortly before dissipation. Five injuries occurred in Wisconsin, though the actual total may have been 12.
Maximum damage intensity was F3 in Iowa and Minnesota and F4 in Wisconsin. The swath of damage between St. Charles and Whitewater State Park, Minnesota, across Olmsted and Winona counties, may have been from a separate thunderstorm, as Grazulis does not count it as part of the same tornado family.

This was the second of two long-tracked tornado families in Wisconsin on May 10. It first formed on the outskirts of River Falls and tracked to the north-northeast. Here, the tornado demolished a summer house, which collapsed onto occupants, injuring four who had been picnicking but had sought safety during the storm. Initially, multiple tornadoes were likely present, as damage was discontinuous until the tornado(es) passed east of New Richmond. At that point, a continuous swath of significant damage began and continued to near Amery. The first fatality, an elderly female, occurred in St. Croix County when her home was leveled, injuring three other people inside. Farther on, in Polk County, two additional deaths took place: one from flying debris, another in a destroyed barn. In Burnett County, the tornado felled a tree, which hit a dairy building, causing a final death. Beyond Amery, scattered, poorly documented destruction occurred for the remainder of the path. A separate tornado likely formed near Minong and dissipated near Gordon, destroying cabins and other small residences. Six injuries occurred across Washburn and Douglas counties, one of which was severe. There were 11 injuries near Amery and 27 along the entire path. Reports from local staff of the American Red Cross indicated that the tornado family destroyed or damaged 113 homes and affected 215 other structures. Collapsing barns killed livestock inside, though the precise number was undetermined. Numerous trees were downed along the path, and utilities were disrupted. The tornado(es) mostly impacted sparsely populated areas. While officially rated F2, the tornado was assigned an F4 rating by Grazulis, based on damage to homes near Amery.

According to an old legend—attributed without corroboration to the Huaco, a local Native American tribe—tornadoes, or at least severe ones, could not touch down in Waco, a city located in a geological depression. Supposedly due to the bluffs around the Brazos River, tornadoes and other severe weather were relatively rare and mild in the city.{{cite magazine |date=May 2013 |title=Looking Back at the Waco Tornado of 1953 and the Lessons Learned... |url=http://www.txdps.state.tx.us/dem/temo/archives/2013/Vol60No5/articles/article2.htm |url-status=dead |magazine=Texas Emergency Management Online |publisher=Texas Department of Public Safety |volume=60 |issue=5 |archive-url=https://web.archive.org/web/20160521140327/http://www.txdps.state.tx.us/dem/temo/archives/2013/Vol60No5/articles/article2.htm |archive-date=21 May 2016 |access-date=25 May 2016 }} The 1953 storm, however, disproved the myth when it tracked directly through downtown Waco as an F5 tornado.
The tornado first formed around 4:10 p.m. CST (22:10 UTC) about {{Convert|3|mi|4=0|spell=in}} north-northwest of the Lorena community. It quickly began damaging structures, destroying a home near Lorena as it tracked north-northeastward. The tornado produced F5 damage outside of the city of Waco.
As it neared Waco, operators of weather radar at Texas A&M University detected a hook echo in association with the parent supercell. This was one of the first times that radar linked tornadogenesis with hook-echo signatures. However, because heavy rain obscured the tornado, it was largely invisible to people in its path. The high-precipitation nature of the parent storm may have heightened the death toll in Waco by delaying appropriate action. The storm also generated baseball-sized hail in its path. The tornado passed close to Hewitt before entering downtown Waco.
As the thunderstorm began pounding the city with rain, many people on the streets crowded into local buildings for shelter, yet few of the buildings in downtown Waco were constructed sturdily enough to withstand the winds, so they collapsed almost immediately. Thirty people died in the R. T. Dennis building alone. Newer buildings with steel reinforcement, including the 22-story Amicable office building (now called the ALICO Building), weathered the storm. The Dr Pepper bottling plant, today the Dr Pepper Museum, also remained standing but sustained damage. Bricks from the collapsed structures piled up in the street to a depth of {{convert|5|ft|m|abbr=out|spell=in}}. Some survivors were trapped under rubble for 14 or more hours; numerous bodies remained buried beneath piles of rubble and for many days were unaccounted for.{{harvnb|Grazulis|1993|p=971}} After devastating downtown Waco, the tornado continued to the north-northeast and dissipated about {{Convert|5|mi|4=0|spell=in}} west of Axtell. While the tornado destroyed homes outside the city, media largely focused on destruction in downtown Waco.
In all, 114 deaths occurred in the Waco area, with 597 injured and over $41 million (1953 USD) in property damage. The tornado destroyed 196 businesses and factories.{{cite news|last1=Young|first1=John|title=The ALICO Building: A Long, Tall Texan|work=Waco Tribune-Herald|date=January 10, 1985}} 150 homes were wrecked. Over 2,000 cars sustained at least some damage.

Following the Waco tornado, attempts to organize disaster relief were stymied by poor organization. Local residents had not expected the tornado and had assumed that the area's geography safeguarded Waco from tornadoes. Initially, the tornado also severed communications between downtown Waco and outlying areas, so assistance was slow to arrive. The chaotic relief efforts eventually spurred greater coordination between civilians and local governments, leading to the development of civil defense. Notably, the Waco event was one of the first instances that proved the effectiveness of radar in tracking tornadogenesis; coincidentally, another such case occurred later in the same year. A retrospective study of the tornado that struck Worcester, Massachusetts, on June 9 revealed that, as at Waco, local radar detected the hook echo that signified the tornado. Researchers concluded that improved communications, coupled with the formation of radar coverage, could lead to accurate tornado warnings, thereby reducing loss of life in future storms. This task proved especially important following the devastating loss of life at Waco and Worcester, along with the June 8 catastrophe at Flint, Michigan, in the same year.{{cite web|last1=Corfidi |first1=Stephen |title=A Brief History of the Storm Prediction Center |url=http://www.spc.noaa.gov/history/early.html |website=NOAA/NWS Storm Prediction Center |publisher=Storm Prediction Center |access-date=27 May 2016 |archive-url=https://web.archive.org/web/20160624003328/http://www.spc.noaa.gov/history/early.html |archive-date=24 June 2016 |date=13 February 2010 |url-status=live }} The state of Texas supported the implementation of 20 radar facilities, each with a {{Convert|200|mi|4=-wide|adj=mid}} radius, that proved successful in reducing death tolls in later tornadoes.{{harvnb|Grazulis|2001|p=90}} The system was known as the Texas Radar Tornado Warning Network and also included communications between weather officials, storm spotters, and local officials. Thus the Waco tornado helped catalyze development of a nationwide severe weather warning system.
The Waco tornado remains the eleventh deadliest tornado on record in the United States and is tied with the 1902 Goliad tornado as the deadliest in Texas history.{{cite web|last1=Edwards |first1=Roger|title=The 25 Deadliest U.S. Tornadoes|url=http://www.spc.noaa.gov/faq/tornado/killers.html|website=The Online Tornado FAQ|publisher=Storm Prediction Center|access-date=27 May 2016|date=29 March 2016}}
