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

NWS officials reported the tornado touched down and lifted numerous times along the path. This tornado was produced by the same parent supercell that produced several tornadoes in the Indianapolis WFO CWA. Most of the damage occurred as it passed through Hartford City. A building at Ag Best, a fertilizer plant, was torn apart. Vehicles were also damaged at this business. The 4-H building suffered damage to its south and east sides. Numerous reports of trees and power lines were noted along the track, with trees falling down across from Southside school in Hartford City.
