The path drawn at its surveyed width of 300 yards (0.17 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

The tornado began over northeast Cottonport near the intersection of Lana Street and Zion Street where homes sustained substantial roof and carport damage while multiple tree branches were scattered. The path continued along a NE motion over rural lands while cross Couvillion Street. Further tree damage and debris was found in nearby farmland along the tornado path. Later the path crossed MP Cutoff Road near Mill Bayou with damage of large tree trunks seen nearby. Southeast of Hamburg the tornado uprooted more trees south of Coco Lake. Hereafter, the tornado took a ENE motion starting along HWY 451 crossing Sutton Lake. After a 15 mile track the tornado ended near a cemetery along HWY 451 and Big Bend Road where further tree damage and the collapse of an old home was found. Maximum winds were estimated at 105 mph.
