A violent tornado moved through parts of Portage and Waupaca Counties in Wisconsin on September 26, 1951.  It was 1 of 3 tornadoes confirmed on this date and 1 of 2 given a rating of F4.  Most of the time, the tornado was in Waupaca County.  Per Thomas Grazulis, three farms were swept away 3 miles north of the town of Waupaca.  He mentions the tornado at this point was near F5 intensity.  Tragically, 5 members of the Rasmussen family were killed at their farm home north of Waupaca.  Mrs. Frances Melliet was also killed near Lebanon.  Here is a newspaper article from The Daily Telegram describing what happened.

A family of five was killed near Waupaca; while a 40 year old woman was killed near New London when a farm home was flattened.

From Thomas Grazulis in Significant Tornadoes

  • Moved ENE from 9 miles SSW of Amherst, passing 6 miles SE of that town.
  • Then moved 3 miles north of Waupaca, south of Manawa, to 7 miles north of New London.
  • Dissipated west of Bear Creek.
  • 3 farms swept away 3 miles north of Waupaca.  Mentions tornado was near F5 intensity here.
  • “All five members of the Rasmussen family were killed as they were cleaning chickens on the porch of their home on the opposite side of the house from the tornado’s approach.”
  • Other fatality was at Lebanon Township, near Sugar Bush.

The path in red is an attempt to show Grazulis’ path from Significant Tornadoes.  He moves the tornado ENE from 9 miles SSW of Amherst  passing 6 miles SE of the town then 3 miles North of Waupaca, south of Manawa, to 7 miles North of New London.  I measured distances out as he has listed and placed a dot.  Not sure how far south of Manawa the tornado traveled.  I have circled Bear Creek.  There is a Bear Creek in Waupaca County and Outagamie County.  Grazulis has the tornado dissipating west of Bear Creek, I am just not sure which one.  Perhaps that ending point near Sugar Bush should be placed a bit further north and west of the Outagamie Bear Creek?  Obviously I am sleuthing here and that plot is not exact but it is interesting to compare.

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