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 EF-1 tornado. The storm touched down just south of Causey Road along Sycamore Avenue in Prairieville, with a tree uprooted. The tornado continued northeast, crossing Causey Road before impacting homes along Galvez Avenue, with large hardwood branches being snapped or broken. As the tornado continued northeast, it crossed several neighborhoods including Malbrough Lane and Agnes Segua Road, with large hardwood tree bases snapped. The tornado gained its peak strength as it crosed Beech Street and Shirleyville Road. Hardwood trees were felled and produced heavy damage to homes in the community. The tornado later caused more damage along Chris Road before crossing Louisiana Highway 933. A barn roof was removed along Jo Boy Road with the tornado lifting before it crossed Bobby Sevario Road. Maximum wind 105 mph, path length 1.71 miles, path width 50 yards.
