From May 22–31, 1973, a destructive tornado outbreak sequence affected the Southern, Midwestern, and Eastern United States.[nb 2][nb 3][nb 4] The severe weather event was the largest and the deadliest outbreak sequence in 1973 with at least 145 confirmed tornadoes causing 24 deaths, 820 injuries, and approximately $280.6 million (1973 USD) in damages. The deadliest tornado of the entire event was a large, violent, long-tracked tornado that crossed the state of Alabama on May 27, killing seven and injuring about 200 people. The tornado, which tracked for almost 140 miles (230 km), was rated F4 on the Fujita scale and largely destroyed the small town of Brent. A day earlier, on May 26, another long-lived F4 tornado in Arkansas caused the highest single-tornado injury total in the outbreak sequence, with 289 people injured. The tornado caused severe damage to the city of Jonesboro and killed three people. Two days before that, a well-documented F4 tornado obliterated Union City, Oklahoma, killing two and injuring four. Other notable, deadly tornadoes struck Kansas and Oklahoma on May 26, including an F1 in Kansas that killed three and a violent F4 that killed five in Muskogee County, Oklahoma. The outbreak on May 27 was reportedly the most severe to affect the U.S. state of Alabama since March 21, 1932.[13]

Center Point, Alabama

[edit]
Center Point, Alabama
F3 tornado
Max. rating1F3 tornado
Fatalities1 fatality, 44 injuries
1Most severe tornado damage; see Fujita scale

A long-tracked tornado family produced severe damage to Center Point, damaging more than 300 residences. Of these, 32 homes of frame construction were leveled, along with 48 trailers. All of the injuries and the fatality were in Center Point.[81] At least 44 people (possibly 76)[13][81] sustained injuries. One person perished in a home that sagged onto the basement, injuring family members sheltered inside.[81] Besides homes, the tornado badly damaged or razed 35 businesses and leveled several structures on farms.[13] A separate tornado, spawned by the parent storm, may have tracked farther to the northeast, ending just east of Gadsden, resulting in a total path length of 50 mi (80.5 km).[81]

Notes

[edit]
  1. ^ All losses are in 1973 USD unless otherwise noted.
  2. ^ 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.[1][2][3][4][5]
  3. ^ 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.[6][7] While the Fujita scale has been superseded by the Enhanced Fujita scale in the U.S. since February 1, 2007,[8] Canada utilized the old scale until April 1, 2013;[9] nations elsewhere, like the United Kingdom, apply other classifications such as the TORRO scale.[10]
  4. ^ Historically, the number of tornadoes globally and in the United States was and is likely underrepresented: research by Grazulis on annual tornado activity suggests that, as of 2001, only 53% of yearly U.S. tornadoes were officially recorded. 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.[3] Most countries only recorded tornadoes that produced severe damage or loss of life.[11] Significant low biases in U.S. tornado counts likely occurred through the early 1990s, when advanced NEXRAD was first installed and the National Weather Service began comprehensively verifying tornado occurrences.[12]
  5. ^ a b c d e f g h i j All dates are based on the local time zone where the tornado touched down; however, all times are in Coordinated Universal Time and dates are split at midnight CST/CDT for consistency.
  6. ^ a b c d e f g h i j Prior to 1994, only the average widths of tornado paths were officially listed.[15]
