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.

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 can remember this day like it was yesterday. It was so scary, I live in Milford, which is about 65 miles away. 


 


Anybody watching the news in New England would have been seeing the tornado cross the Conneticut River on live tv, it was pretty nuts. 


News reports started out saying that a funnel cloud was sighted in Westfield, and then a small tornado crossed the river and dissapated, but it was just obstructed form the camera. The NWS expired the tornado warning just a few minutes later, although at this time downtown sprigfield was being crippled by the powerful tornado, which eventually came out being a strong F3, although some of the damage could have been an F4. After more reports of the tornado in Springfield and Wilbraham came in, the warning was reissued and the news crews were all over the storm, the tornado then went into Monson and did extreme damage, almost 80 buildings were destroyed in Monson. It then went into  Brimfield, and reached it's maximum width of half a mile, deforesting any of the trees in it's path, one person was killed in Brimfield in an RV park. The last of the pictures and videos were from Brimfield. By this time the warnings were still out, but the news crews reported that the tornado had dissipated somewhere in monson, saying that tornadoes in Massacusetts are "short lived" and don't go far. The tornado then tracked through Sturbridge, Southbridge, and finally dissipating in Charlton. The storm then headed in my direction, but no other tornadoes were in this same supercell. News crews then went back into springfield, showing partially collapsed multi-story brick apartments on Main street, but another thunderstorm came out of nowhere, and the crews went bak to hiding. At the end of the day, the news reported "at least seven tornadoes in Western and central Mass." and at least 4 deaths, and that dozens more were expected. It was later found that there were three deaths, the fourth was unrelated to the storm. Two people died in west springfield, one being crushed by a tree in their car, and another when their house collapsed. The third was in Brimfield, as I already mentioned. It was also disovered that there were only four tornadoes in Massacusetts, this F3 which tracked about 39 miles from Westfield to Charlton, an F1 tornado in Wilbraham, which was from the later thunderstorm, an F0 in Brimfield, also from the later thunderstorm, and another F0 in Fiskdale (a neighborhood in Sturbridge). Two more tornadoes occured in Maine, about two hours before this tornado. http://en.wikipedia.org/wiki/2011_New_England_tornado_outbreak
