On April 9, 1919, a tornado outbreak occurred in the Southern Great Plains of the US, producing numerous strong tornadoes and killing at least 92 people, mainly in portions of North and East Texas. The entire outbreak occurred overnight and produced at least seven intense, deadly tornadoes, the deadliest of which was a long-tracked, extremely violent F4 in East Texas that killed 24 people and injured 100 others. A separate F4 long-tracker in the same region killed 17 others and injured 60 more. A deadly F3 also claimed nine or more lives in southern Oklahoma, and a long-lived F3 in East Texas crossed into Arkansas, killing eight. Several of the tornadoes in this outbreak may have been families of two or more twisters.[nb 1][nb 2][nb 3]

Notes

[edit]
  1. ^ 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. ^ 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of the scale in 1971, tornadoes in the United States were officially unrated.[2][3] While the Fujita scale has been superseded by the Enhanced Fujita scale in the U.S. since February 1, 2007,[4] Canada used the old scale until April 1, 2013;[5] nations elsewhere, like the United Kingdom, apply other classifications such as the TORRO scale.[6]
  3. ^ 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.[7] Most countries only recorded tornadoes that produced severe damage or loss of life.[8] 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.[9]
  4. ^ 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.
  5. ^ Prior to 1994, only the average widths of tornado paths were officially listed.[10]
