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 tornado touched down in the morning near NE Sixteenth Rd. in northeastern Jefferson Davis County where a few trees were uprooted. The tornado continued northeast at an estimated EF-0 intensity across Clem School Rd. where numerous trees were damaged or uprooted and some tin panels were removed from an outbuilding roof. The tornado intensified as it approached the Simpson County line, where a more concentrated area of uprooted trees and small snapped trees supported an intensity of EF-1, with peak winds estimated up to 90 mph. Continuing into southeastern Simpson County, the tornado crossed Scott Harrington Rd. and Newhope Rd. where trees were downed, some roofing material of a home was damaged, and a carport and outbuilding were. The tornado weakened as it crossed Berry Lott Rd., with large branches down and some shingles removed from a home. The tornado traveled a short distance further northeast and dissipated. Maximum estimated winds in Simpson Cunty were 90 mph. The total path length across the two counties was 6.53.

The wider storm

Severe thunderstorms moved across Mississippi during the evening and overnight hours of the 13th into the 14th, with flash flooding across areas of the Delta and several tornadoes. Severe storm coverage diminished during the night, but storms became severe again during the afternoon of the 14th as a cold front interacted with a warm and unstable air mass in the region. Tornadoes on the 14th were generally along and south of the Interstate 20 corridor with severe storms continuing into the evening.

Began near Jaynesville (31.7740, -89.7638).
