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

Damage from the tornado largely consisted of several large pine trees snapped in half and several large oak trees uprooted. Numerous large branches were blown down. A few structures had roof damage and at least one large metal outbuilding had heavy damage.

The wider storm

Widespread heavy rainfall and strong to severe thunderstorms affected much of southeast Louisiana over a two day period. The adverse weather was the result of a series of strong upper level disturbances moving across the lower Mississippi Valley in advance of a strong and slow southward moving cold front.

Began near Folsom (30.6044, -90.2297).
