NOAA recorded where this tornado touched down but not where it lifted, so it appears as a point. Other tornadoes recorded nearby that day are shown faint.

What F2 means. This tornado was rated on Fujita’s original scale, used until 2007. F2 meant considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted; the scale paired it with winds of 113–157 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.
