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 is a continuation of the Shelby County EF-1 tornado that touched down just west of Toledo Bend Reservoir shortly before midnight on April 24th. This tornado moved across Toledo Bend Reservoir as a waterspout, and back onshore in Northwest Sabine Parish as a tornado, where it crossed Highway 191 just south of Highway 174 before turning more easterly crossing Golden Road, snapping and uprooting numerous trees along its path. The tornado tracked through the town of Converse where several trees were snapped and uprooted before crossing Highway 171 and Highway 174, and led to additional tree damage on Harrison Road, Cooper Lane, and Bolivar Road before moving into Southeast Desoto Parish. The maximum estimated winds from this tornado as it moved throughout Northwest Sabine Parish was 105 mph.

Approximately five homes reported major damage, while fifteen other homes suffered minor damage from the tornado. A church also suffered damage from this tornado as well.

The wider storm

A strong closed upper level low pressure system advanced east across Central Texas during the evening hours of April 24th, which helped to mix a warm front north into portions of Deep East Texas and Northcentral Louisiana. As a result, warm, moist, and unstable air began to build north along and south of the front, as steepening lapse rates aloft spread east along the axis of increasing large scale forcing ahead of the low. This resulted in an increase in scattered to numerous showers and thunderstorms near and south of the warm front from the late evening hours of the 24th through the early morning hours of the 25th across East Texas and North Louisiana. Coupled with the strong wind shear present across the expanding warm sector, several supercell thunderstorms developed, with one supercell spawning six separate tornadoes from San Augustine Texas northeast to Eastern Union Parish Louisiana, directly impacting the cities of San Augustine Texas and Ruston Louisiana along its 150+ mile track across the NWS Shreveport County Warning Area. In fact, this supercell spawned another tornado across Northwest Morehouse and Southern Ashley County Arkansas, to complete its nearly 180 mile track before dissipating. Other isolated supercells developed near and south of the warm front which spawned tornadoes across Northern Caddo Parish and Central La Salle Parish in Northern Louisiana, with other severe thunderstorms producing damaging winds across portions of Northcentral Louisiana as well, before the storms exited the region around daybreak on the 25th.

Began near Toledo Bend Res Nort (31.7072, -93.8130).
