A tornado developed near 130th and J Avenue in Page County Iowa, producing damage
to outbuildings and trees as it tracked toward the east and northeast. Large sheds
were destroyed, and some homes began to sustain damage near the Page Montgomery
county line and O Avenue intersection. The tornado continued to intensify as it
moved northeast and became quite wide as it moved northwest and north of Villisca.
A large communications tower was toppled west of Villisca, and multiple farms were
badly damaged northwest of Villisca. EF-2 damage was observed at a farmhouse near
240th Street and T Avenue, and also at a home near Highway 71 and 235th Street. A
campground was hit at Hacklebarney Woods, as well as multiple homes along V Avenue
and Vine Avenue. Campers were tossed and significant tree damage occurred in this
area, but most permanent structures remained standing. The tornado neared its
maximum width at this location, and the damage pattern was evident in having a
broad area of EF-1 type damage with embedded areas of more intense damage to trees and
buildings, likely indicating a multiple vortex tornado. The tornado crossed into Adams
county north of 210th Street.
