EF1 tornado in Jefferson Davis Parish, Louisiana

The same supercell that spawned the tornado near Lake Arthur produced a large, long track multiple vortex tornado that touched down south of Highway 90 just east of Farm Supply Road to the southeast of Roanoke. The tornado moved to the north-northeast and crossed Highway 90 around 2 miles east of Roanoke, it produced a half-mile wide damage path along the highway. In this area, a farmhouse received minor damage to the roof, a barn was moderately damaged, and a metal silo was destroyed. In addition, a few trees and several large tree limbs were blown down, and several wooden transmission power poles were snapped in half.

Continuing northward, the tornado then passed across Interstate 10, blowing an 18-wheeler and several cars into the median of the highway, and knocking down a few trees. The driver of the 18-wheeler was injured and required hospitalization, and the eastbound lanes of the interstate were closed for several hours. An NWS employee located 1 mile east of the tornado took photographs and video as it crossed the interstate. Further to the north, several trees were blown down along Aaron Road and Dave Williams Road, and the metal roof of a home on Koll Road was blown off. After crossing Grand Marais Road just west of Elton Drive, the tornado damaged the carport of a home and severely damaged a barn.

The tornado then began moving north-northwestward, blowing down a few trees along Bryan Road and Ardoin Road, before crossing Highway 102 about 2 miles west of Hathaway where it blew down more trees. Curving more northward, the tornado then began moving along Highway 395, where it blew down trees along both sides of the highway and caused minor damage to the roof of one home on Bucklin Road. Continuing northward through the community of China, the tornado finally dissipated to the north of China Cemetary Road, just west of Highway 395.

A line of strong to severe thunderstorms developed along a cold front and moved eastward across southwest Louisiana during the late morning and afternoon hours. Ahead of the line, numerous supercells developed across the northern Gulf of Mexico and moved northward across the area. Two of the supercells spawned a total of 6 tornadoes, while several reports of damaging winds were received with the line of storms. All of these storms combined to produce widespread heavy rainfall and flash flooding across the entire area.
