What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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 tornado touched down in Jefferson Parish, southwest of Terrytown. It moved northeast through Jefferson Parish. As it moved northeast through the Westbank, it caused minor tree damage as well as structural damage. This damage consisted of minor roof, siding and fence damage. The tornado continued into Orleans Parish.

The wider storm

An upper level system moved into north-central Texas on March 22nd. Thunderstorms began developing in the unstable warm sector ahead of a cold front moving east into east Texas and western LA. Very strong low and mid level winds ahead of the cold front brought in ample low level moisture with dewpoints reaching into the 70's near the coast. As temperatures at the surface warmed into the 80s and temps aloft dropped, the atmosphere steadily became unstable. Increasing shear combined with the very unstable atmosphere set the stage for 5 tornadoes to develop, one of them was violent, resulting in 2 fatalities.

Began near Terrytown (29.8849, -90.0535).
