The strongest tornado in Washington history had origins west of Ruston, before shifting east, destroying 2 homes on the west side of town, and causing a pileup on North Pearl Street. It then continued down pearl street, damaging more homes and a 7-Eleven. The tornado remained thin, but rapidly strengthened as it approached north 30th street, where it turned northeast and crossed the North End Reservoir. Homes on North Shirley Street were left with only interior walls remaining. The tornado rapidly weakened and dissipated at 12:50 PM near the St. Joseph Medical Center. One person was killed in the tornado, and 15 were injured.
