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

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.

I was 13 years old and this tornado passed just to the west of my farm. The mapped path is shown about 200 yards north west of my uncle's farm and his place took on good deal of damage. Their home lost a large bay window and the roofs of many outbuildings. During the event he was pinned down in one of his sheds holding his dog Nick in one oarm and had his other tighly around a tractor axle. After the tornado was over I remember it being dark out and my cousin was drving over to see if his parents, my aunt and uncle, were alright. We saw his truck stop as every utility pole on 600N where the tornado crossed was down. He had to drive thru pasture to get is parents.

The next day, a Sunday, we missed church to start celan up and many folks had heard our area was hit so about noon farmers and others began showing up to pitch in with clean up. One interesting item was the amount of gawkers that came out from town to follow the damage path. A couple "oddities". That some night a tornado hit Petersburg, IN about 160 miles SW of my home. In the debris at my uncle's were checks from a Petersburg family we located and they confirmed their house was hit. Now this particular tornado started in Lawrence County some 120 or so NE of Petersburg but it must have been the same cell as the Petersburg torando that night. Another oddity is that the family directly to the west of our farm less than 3/4 mile have been hit twice by F4 tornadoes. They were hit in the April 1974 outbreak of which one came thru our county and this 1990 tornado. They have a house now that you all should see, very reinforced, a house within a house, kind of.

All I remember from the event as it was happening was that as radio gave the location of the siting, my father and I stepped onto our back steps facing west with trees and buildings blocking vision to the SW. It was breezy and lighting but not fiercely. In the distance I heard what my father displaced as a jet going overhead. At that point the tornado was proabably a mile SW of the farm. It was not but a minute that the wind just came in force and dad and I yelled for my brother and mother to get to the basement. I remember what seemed to be another two minutes of a sustained wind with no breaks then a feeling that a "wave" hit our house, a "sway" feeling if you have been in a tall building. Once that passed we went up to see what we could. We lost fences and barn roofing but no known structure damage. Then the night proceeded as I stated above. 1990 drove home my passion of tornado research. I would like to increase my involvment in storm reaserch some day when I am done with my "day job" :) If I were to go back to school today I might have treated going into meteorology seriously, instead I am a government offcial in Indiana...but still hard to stay put when the storm warnings are out. LOVE THE SITE!!!
