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

The National Weather Service conducted a storm survey in Sabine Parish in Louisiana and concluded that damage was the result of an EF1 tornado with possible multiple vortices. The tornado first touched down northeast of Many along Hwy 6 and primarily paralleled HWY 6 to just southwest of Many where it turned right and continued on a more eastward track towards Robeline in Natchitoches Parish. Damage throughout Sabine Parish consisted mostly of uprooted and or snapped trees in the northeast corner of the parish. This tornado continued into Natchitoches Parish. Maximum winds are estimated at 95-105 mph.

The wider storm

A very volatile atmosphere developed during the late afternoon...evening and overnight hours of April 26th across the Four State Region. An area of low pressure moved from the Texas Hill Country into Northeast Texas during the afternoon. Meanwhile, a warm front had moved northward from central Louisiana and was oriented west to east near the Arkansas/Louisiana state line. A dry line had moved just east of the I-35 corridor of North Central Texas and a strong cold front trailed the dry line. Very strong speed and directional shear was noted in the low and mid levels of the atmosphere such that supercells developed. Many of these produced tornadoes across the region. Other storms produced strong straight line wind gusts with bowing segments and large hail.

Began near Ft Jessup (31.6170, -93.4060).
