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 tornado began just to the southwest of Sudbeck Road and downed hardwood trees in this area. It then continued northeast, snapping tree limbs and uprooting a few trees along its path in the northern part of Holmes County. The tornado then crossed into Carroll County and dissipated along Highway 37. The total path length for this tornado was 9.16 miles and the maximum estimated wind speed was 90mph. The maximum width was 400 yards, which occurred in Holmes County.

The wider storm

During the early morning hours of April 30th, a squall line of severe thunderstorms developed across central Louisiana and pushed eastward across the ArkLaMiss. The line intensified as it approached the Mississippi River and caused wind damage and tornadoes. As the convective system evolved into Mississippi, numerous tornadoes developed along the advancing line, with the most prolific damage occurring along the track of a large meso-scale convective vortex (MCV). This feature tracked roughly from Claiborne County through western Hinds/Madison, eastern Yazoo, eastern Holmes, southeastern Carroll, Montgomery, and northwestern Webster counties. This corridor is where the most significant damage occurred, as well as one fatality. Flash flooding, hail, and other wind damage occurred as these storms moved through.

Began near Bowling Green (33.1769, -89.9856).
