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

This tornado developed and downed several trees along Fred Ellzey Road, and caused moderate damage to the roof of a large home north of the road. The tornado moved northeast, snapping several trees and heavily damaging an outbuilding as it crossed West Creek Road. The tornado then snapped a few trees and damaged the roof of an outbuilding just before crossing Highway 84 where it dissipated. Maximum wind speed was estimated at 95 mph.

The wider storm

During the early morning hours of November 16, a supercell thunderstorm tracked across the south-central and southeastern portions of Mississippi producing three tornadoes. Actually, this particular cell was responsible for two other tornadoes, one in southeast Louisiana and another in west-central Alabama. This activity occurred as an upper level disturbance moved over the region and combined with increasing wind shear and instability. Initially the storm activity associated with this disturbance was rather weak. However, after 3 am, there was a resurgence in activity, and storms intensified across southeast Louisiana, and southern and southeast Mississippi. The storm that produced all the damage developed in a location where instability and high wind shear were maximized. The result was a cyclic supercell that produced several tornadoes. Across the NWS Jackson service area, three tornadoes impacted four counties: Marion, Jefferson Davis, Jones, and Jasper. Two of the tornadoes were rated EF1 and the other rated EF2. Nearly two dozen structures were damaged or destroyed by these tornadoes and 15 people were injured.

Began near Hebron (31.6608, -89.3275).
