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.

What the National Weather Service wrote

The tornado developed near Mary's Lake and moved across corn and bean fields before striking a farmstead just northwest of County Roads 10 and 27. Nearly empty grain bins were dented, sheds demolished, and a 32 foot camper was destroyed. A house lost its garage, part of its roof, and was pushed off its foundation. A large vehicle was also pushed a couple of hundred feet. Shortly after hitting the farmstead, it veered southeast into some fields, where it dissipated.

Began near Echols (43.9167, -94.6500).
