The path drawn at its surveyed width of 50 yards (0.03 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

There is some uncertainty where this tornado first touched down and dissipated due to a number of farm fields and limited damage. Based on radar information and surrounding evidence, it was determined that it started in a field. The greatest damage occurred near the intersection of School House Lane and Sidney White Rd. A well-structured home had significant roof damage, and a playhouse and shed were completed destroyed. On the University of Louisiana-Monroe radar, a tornadic debris signature was visible near this home. A number of uprooted trees were sporadically down around the edge of the circulation and were probably caused by straight line winds. On Hwy 425, north of Oak Ridge, a few power poles had to be replaced. This is where it was determined that the tornado dissipated. The maximum wind speeds with this tornado were 95 mph.
