“It looked like we were driving into a dump site, or a burned out slum, or what I would imagine a bombed out city would have looked like after World War II.” – These are the words of Steve Ulmen.  He was 22 and a senior member of the Mankato Civil Air Patrol squadron when an F5 hit Tracy, MN on June 13, 1968.  He was dispatched to Tracy on a search and rescue mission.  (Minn Post).

Eleven tornadoes were confirmed on June 13, 1968.  5 were in the state of Minnesota.  All rated F0…but one.  This devastating tornado struck just after 7pm.  It traveled close to 13 miles (Per Storm Data Publication).  There were 9 fatalities.  The exact number of injuries is not clear.  There were at least 125.  110+ homes had major damage.  13 farms and 10 businesses were destroyed.  Per the Minneapolis Star (June 14, 1968), the force of this tornado lifted a boxcar from the tracks and moved it 1 1/2 blocks into a residential section.

The path is too far west.  The tornado went through downtown Tracy.  Also it ended in Redwood County, that is not indicated here.    

Note:  Exact tornado path may not be straight and/or continuous.

Here are the official coordinates for the path from NCDC – this is broken down in segments by county:

Murray County:  

Start:  44.17 / -95.75   –  End: 44.20 / -95.70

Lyon County:

Start:  44.20 / -95.70   –   End:   44.27 / -95.58

Redwood County:

Start:  44.27 / -95.58   –   End:  44.30 / -95.60

This plot looks good actually until the final segment.  There are NO indications that this tornado made a sudden jog to the northwest.  

Tornado Path - Adjusted

Based on the narratives of the path in the Storm Data Narrative and by Thomas Grazulis in Significant Tornadoes, we adjusted the track map to include the starting lat/lon from SPC and NCDC and ending it in Redwood County (44.27 / -95.58).  Even this plot seems too far west because Tracy should be in the crosshairs of the tornado.

Path Length:

  • SPC/NCDC have a 9.1 mile path length.
  • Grazulis and Storm Data have a length at 13 miles.

Max Width:

  • Grazulis has a width of 600 yards.
  • Remaining sources list the width at 150 yards.


  • SPC/NCDC list 150 injuries.
  • Storm Data/Grazulis have 125 injuries.


  • Storm Data only lists Lyon County.
  • Remaining sources have the tornado path going trough Murray, Lyon and Redwood.  
  • When NCDC breaks down the path length in each county, it lists 2.3 miles in Murray County, 6.8 miles in Lyon County and 0 miles in Redwood County for a total of 9.1 miles.  If you look at the map section above, NCDC coordinates do bring the path into Redwood County for several miles not zero.
