In between the first and last tornadoes, twisters rated as F4 storms smashed into the tiny towns of Comfrey and Lake Hanska before terrorizing residents in St. Peter. The damage tally in the south-central Minnesota City included nearly 2000 damaged homes, and about 200 of those houses were completely destroyed. The campus of Gustavus Adolphus College took a direct hit and sustained about $50 million in damage.

Two people lost their lives during the tornado outbreak. A 6-year-old boy in St. Peter and an 85-year-old man living near Lake Hanska were killed.
