What F1 means. This tornado was rated on Fujita’s original scale, used until 2007. F1 meant moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken; the scale paired it with winds of 73–112 mph, figures later judged too high, especially toward the top of the scale, and revised downward in the Enhanced Fujita scale. Ratings then, as now, came from the damage.

Near this intersection, a grain bin was heavily damaged and an empty semi trailer truck was blown into a pond. Numerous trees and power lines were downed along the path. Tree damage clearly denoted the path length and width along the track. An eyewitness near the intersection of Y and H highways witnessed the tornado formation and rushed to one of the damaged homes. Thew two minor injuries were to residents of two mobile homes damaged 3 miles NW of Fillmore.
