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.

The track on this map is not correct as the first touchdown occured close to the intersection of Kenowa SW and Jacob Street SW (42.875, -85.781) where it damaged several homes. From there the path went toward the intersection of 36th Street and Burlingame (42.899, -85.705) where the roof of a Shell gas station was removed and the school across the street was damaged. Next stop was Darling Freight and K-marts near the intersection of 28th St and Buchanan (42.914, -85.675). From there the tornado skipped a little till hitting the church on Alger and Madison (42.919, -85.657). Basically the path shown has a more southern start and a slightly southern finish from what has been shown. I do not know where the data came from but I was in the storm and witnessed the damage

rtunas is correct. I was riding in my family's auto when the siren's went off. We had heard on the radio (CB) that the tornado had been spotted @ 44th and wilson, so my father tried to head to my grand parents home in wyoming. As we headed south on Clyde Park Avenue, we intercepted the storm just south of the Wyoming Water tower (it is no longer in that area) on Clyde Park. Our station wagon was stopped (as we were praying for Jesus's deliverance and protection), facing south. A few seconds later we were turned 90 degrees facing east. We were between Coltrain and Cricklewood. We had storm debris (2x4 x36", and shingles), under the hood of the of our 1967 Buick Wagon and all the windows had sand blast damage to them. The house on the north side of Cricklewood had part of its roof removed as I recall. The tornado skipped around it seemed. The Darling Freight terminal was damaged and the K-mart at 28th and Buchanan had roof damage, also. Also the Church @ Alger and Madison had the center of it destroyed. That is just 100 feet south of Alger on Madison. When we spotted the tornado it was white in color and was just about tree height. That was about 7:08 pm. I was 14 years old and wanted to become a weatherman. That day, however, changed my spiritual life and I became a child of the King, Jesus. He still saves today.

I remember this tornado. I was 11 years old; it must have hit unexpectedly because I was separated from my parents, playing with freinds, I think it was the Potters who lived across the street from my house, 3621 Taft Ave. All of a sudden, I was told there was a tornado and wisked away to the Potter's basement. I remember it was dark as night almost - pouring rain and maybe hail. We stood upright against the west wall of their basement; I heard the roaring train sound of the tornado. I was terrified. I remember other noises; crashing noises. I was scared for my mom and dad; wondering if they were okay at my house across the street. I thought my sister was with me, but she remembers differently.


We came out of the Potters and I quickly found mom, dad, and my sister. I remember walking down the street the next day seeing more serious damage down the street (Taft) south, twoards the school at the end of Taft where it turns into Hubble. I remember seeing a twig stuck in the wall of a garage; and a garage ripped apart. The tornado must have touched down somewhere near there. I also remember driving down 28th street a few days later near US131 seeing the roof ripped off from the Darling Freight building. This was the most terrifying natural event of my life (so far)
