A tornado moved through the south side of Ottawa on the evening of Monday, April 13. After surveying the damage, the National Weather Service rated it EF2, with peak winds near 125 mph. It was on the ground for 7.3 miles, from about three miles southwest of town to three miles east, and was up to 100 yards wide. KOFO noted it was the first tornado inside city limits since 1880.

The heaviest damage ran along 17th and 15th streets. The Knights Inn at 17th and Main was nearly destroyed, and the former HD Lee plant, Hope House and several nearby businesses lost walls or roofs. Power poles came down along 15th Street out to I-35.

East of town, a house was badly damaged and three people inside had minor injuries. No one was killed.
