Note: This approximate tornado path has been generated from data provided by the NCDC.

The Tornado History Project generates approximate paths through separate historical archives provided by the Storm Prediction Center (SPC) and the National Climatic Data Center (NCDC). Paths generated from the NCDC data are typically more detailed, but neither archive gives exact path information. There are several reasons that paths may be inaccurate:

  • Tornado touchdown and liftoff coordinates were recorded with only 2 digits of decimal precision (i.e. [33.72, -86.15] vs [33.71689, -86.15463]). As a consequence, the observed points on the map may be slightly off from actual. Note that beginning in 2009, up to 4 digits of decimal precision are given.
  • Coordinates have not historically been calculated via GPS (Global Positioning System). Thus, tornado touchdown and liftoff coordinates should be considered as estimates only.
  • Tornadoes may not have been in contact with the ground for the entire path as depicted on the map. Storm damage in any location depicted under the "path" should not be inferred.
  • Although paths are drawn as straight lines between any two sets of coordinates, the tornado may have "zigzagged" in some way.
  • Although paths are drawn as uniform thin lines on the map, it is likely that the tornado changed size over its lifetime. Damage in any location depicted under (or not under) the "path" should not be inferred.

Even with the above in mind, the data is the best available. If you see a path that is depicted incorrectly, please post a comment in the tornado forum indicating why you belive the path to be incorrect.

Paths generated from NCDC data are typically more detailed due to the way coordinates are listed in each archive:

  • SPC database - A maximum of 2 coordinates (touchdown and liftoff) is given for each tornado, or each state segment of a tornado if it is a multi-state tornado. Thus the vast majority of paths are depicted as simple straight lines.
  • NCDC database - Some tornadoes have mutliple sets of coordinates within any state, generally corresponding to entry and exit points by county. Thus, since more coordinates have been used to draw the path, the depicted path should be more accurate. Having said that, most tornadoes do not have additional path data in the NCDC archive. When they do, paths are drawn from the NCDC data.

The following statistics and definitions are derived from the Storm Prediction Center (SPC) historical tornado archive. The Tornado History Project can not guarantee the accuracy of the underlying data within the SPC historical tornado archive. However, the data as presented here is guaranteed to match the SPC data, except where noted.

Some definitions will not be given since they are obvious (i.e. "Date", "Time", etc...)
Special Note: This site uses a unique index number to identify each tornado. This index number is not a part of the official historical tornado archive.

E (Error) (tornado search table only) - A yellow box indicates that the tornado record contains a suspected error. A red box indicates that the tornado record contains an error and has been modified from the official source. Hover over the box for the error text.
Map/Forum (tornado search table only) - Clickable icons for further content related to a tornado.
State - The state or states affected by a tornado.
Fujita - The Fujita scale is an attempt to classify damage from a tornado. F0 being the least damaging, F5 the most. For 2007 and beyond, the Enhanced Fujita (EF) is given.
Fat. - The number of fatalities attributed to the tornado.
Inj. - The number of injuries attributed to the tornado.
Width - Width in yards. It is unclear if this indicates a maximum width or mean width.
Length - Length of tornado path in miles. Note the entire track length is not necessarily all on the ground (some tornadoes "hop and skip".)
Damage - Prior to 1996, this is a range by dollar amount. For 1996 and later, actual damage estimates are in millions.
Crop Loss - Added in 2007. Given in millions of dollars.
Lat/Lon - Contains two sets of coordinates:

  • Touchdown Latitude/Longitude - For single state tornadoes, and the overall record for multi-state tornadoes, the approximate touchdown location in decimal degrees. For the state specific records of multi-state tornadoes, entry point into the state in decimal degrees.
  • Liftoff Latitude/Longitude - For single state tornadoes, and the overall record for multi-state tornadoes, the approximate liftoff location in decimal degrees. For the state specific records of multi-state tornadoes, the exit or lift-off point from the state in decimal degrees.

St. #. - The state tornado number assigned to the tornado for that specific state for that specific year. Generally, state tornado numbers were assigned in the order the tornado occurred, but that is not always the case.
SPC # - The tornado number as assigned by the SPC. Tornado numbers are not unique and reset each year. Generally, tornado numbers were assigned in the order the tornado occurred, but that is not always the case.

Well, i have a little to add mainly that i was in this one . I was about 5 years old but i remember it plain as day. We lived in Sapulpa. I recall it was in the evening we were looking at TV i don't remember what day it was mayby it was sunday I want to say that the wizard of oz was showing but im not quite sure. I guess they had been anouncing flashes on the Tv about severe weather ,but to make a long story short it ripped Sapulpa apart as i heard . i know it tore up our community. not to mention that it blew our house off the foundation and we were still in it at the time.I remember it got real quiet, then it start hailing like crazy. seem like it quit hailing and then all hail broke loose it sound like a heard of trains coming through tell you the truth it sound like it went right through our yard from the west and it was so pitch white you couldn't see anything and the west side windows blew out.and you could hear the walls cracking and coming apart.I guess the angels was with us because that was all it did to our house. I think we got under the bed.I , my mom, and my brother. After it kind of died down it had turn dark.So we left the house and went up to our neighbors house a couple of houses up from us and stayed there all night.It was really frightening. If any one has any pictures of this event could you share them with me . thank you . or

This event was related to a significant tornado outbreak in Oklahoma, Arkansas, and southwestern Missouri. The majority of the activity occurred in central/eastern Oklahoma and Arkansas. There was a high ratio of significant (F2-F5) events on this date. Surface based lifted index (LI) values were exceptionally unstable (-7 to -9). A 500 mb jet maximum produced wind speeds in excess of 72 knots. The massive F5 event was described as a "huge, white" tornado that resembled the shape of a barrel (Grazulis, 1993). Thomas P. Grazulis cites a continuous path length of 70 miles, although the official database lists a 71 mile track. The tornado passed two miles east of Prague, but the database depicts a direct strike. The tornado destroyed fourteen farm sites between the towns of Prague and Paden. More than 100 homes were obliterated in the northern and western sections of Sapulpa, where the most severe destruction occurred. The homes incurred F5 damage. Homes were also swept away from their foundations south of Bristow. Three fatalities occurred in this vicinity. The funnel fortuitously lifted prior to passing over Tulsa. It was observed over the city, where it did not reach the ground. This funnel primarily affected rural areas; the only substantial populated area was Sapulpa. Three deaths were reported. The tornado purportedly destroyed most of the vegetation in the Cross Timbers region. The reports also indicated that the tornado removed ~6 inches of topsoil from the hills.
