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

A NWS storm survey found damage consistent with an EF1 tornado east-southeast of Thibodaux. The tornado touched down just south of Louisiana Highway 1 along Reith Lane, snapping live oak hardwoods nearly 2 feet in diameter. Two well constructed storage buildings had major roof damage. These buildings had remained intact with metal roofs since the 1920s. Another well constructed storage building in the same vicinity had major wall and roof damage, with a carport above it being lifted and destroyed. Large sections of the roof of a home in the same lot had damage from the storage building debris. The tornado tracked north-northeastward, crossing Highway 1 and Bayou Lafourche, moving a multi-ton storage container several inches from its original location. The tornado continued north-northeast, taking out 3 large hardwood oak branches 16 inches in diameter before it lifted. Estimated peak wind 95 mph, path length 0.27 miles, path width 100 yards.
