When it initially touched down, it produced sporadic tree damage near the intersection of County Road E-60 to L-14, in Monona County. The twister moved northeast and hit a farmstead, downed power lines and destroyed a grain bin.

It continued northeast through the Loess Hills, producing varying degrees of tree damage, before crossing County Road E-54 and 277th Street, where it destroyed more trees and a few outbuildings. The twister continued its trek northeast across 258th Street, where it hit another farmstead, tearing-off part of the roof off of a house, destroyed some outbuildings and several more trees.

Before it dissipated, the tornado crossed another road and knocked down power lines. No injuries were reported. Officials say the EF-1 twister produced peak winds of up to 90-miles per hour. An EF-1 tornado typically has wind speeds ranging from 86- to 110-mph.
