This is the second damaging tornado from the cyclic supercell on May 11, 2000 in Blackhawk county, Iowa. This tornado formed to the southeast of the decaying original tornado and ended up damaging part of the town of Dunkerton. Unfortunately, Dunkerton had been damaged in 1999 by floods, and now was to suffer again only a year later. The tornado traveled in a northeast direction and clipped the western side of town causing up to F3 damage to some buildings.
