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.

Statistics   Definitions |?|

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 first spotted this funnel cloud from home. It appeared to be over the Deerwood area and headed in a South Easterly direction towards the city of Garrison. 


I was a deputy sheriff so I go into the take home squad and sped to Garrison to warn te public as there were no outdoor warnings at that time. I let dispatch know what I had seen and they notified other deputies and emergency services as well as the local radio stations so that they could warn the public as well. 


Once in Garrison, I drove about warning people to take cover. There was one fishing launch on the lake and I notified them to seek shalter at shore. As the funnel cloud approached to the West of Garrison a pilot called dispatch and notified them that the funnel then was a tornado and that it was on the ground West of Garrison. The pressure caused my ears to pop as the tornado struck Garrison. I could see boards, shingles, tree branches and assorted debries swirling around at a fast rate of speed. 


I saw the debrees in the air as I parked the squad in the Y club parking lot. I watched as it took out trees less than 30 yards from where I was parked and also saw it cause a pull behind camper trailer to explode into pieces. It went across Hwy 169 and knocked the big walleye statue over and set down in the lake. there was hail the size of baseballs falling all around the tornado as it sucked water from the lake. There were huge dents in the squad but fortunatly non of the windows were broken out.


The wind force was such that it actually started to pick up the rear of the squad car and a trailer which was loaded with a big boat and attached to a vehicle next to the squad started to lift off the ground and move from side to side. It was easy to see every piece of dirt being sucked from the tar parking lot and into the tornado. 


The winds calmed as the tornado went off across Mille Lacs lake in a Southeasterly direction.  It was easy to see the tornado all the way across to the other side of the lake.  there were trees down all over in the city of Garrison and signs of damage to assorted buildings. Thankfully there were no injuries partly because the State patrol had stopped traffic a few miles South of Garrison until the tornado had gone a safe distance out into the lake. 


I wish that I had thought to grab my video camera as I left home to head to Gqarrison as it would have been a very impressive video with being so close to the otrnado. All hat I have is the memory in my mind. Rumor had it that when it reahed the East shore of Mille Lacs that there were actually fish falling from the tornado. I was never able to barify that, however.


Just anoher day in the life of a law enforcement officer.LOL
