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 Demopolis tornado touched down approximately 3 miles southwest of the city of Demopolis, just west of Maria Avenue and south of U.S. Highway 80. The tornado then tracked north northeast and crossed U.S. Highway 80. Several large trees were knocked down and the fallen trees produced varying degrees of damage to homes. Additional large trees were knocked down and subsequently destroyed several mobile homes. One apartment complex sustained significant roof damage. A few mobile homes were rolled over. The tornado continued north northeast across the western part of Demopolis snapping trees along the path. One warehouse had an entire wall collapse. Several floats being prepared for the holiday parade were thrown some distance and damaged on Lake Demopolis. The tornado lifted around just east of U.S. Highway 43 at Lake Demopolis.
