What the National Weather Service wrote
This tornado touched down on the southeast side of Port Gibson, near the Natchez Trace Parkway. As the tornado tracked north-northeast, it snapped hardwood trees and uprooted numerous trees. One tree fell on a house on Smith Street, which caused roof damage. The tornado then tracked toward the northeast, crossing the Natchez Trace Parkway and Highway 18. Here it continued to snap or uproot trees and also caused roof damage to a structure. An extensive area of trees were snapped or blown down just before it crossed the Natchez Trace corridor a second time. After crossing the Natchez Trace Parkway again, it continued to snap and blow down numerous trees. As the tornado tracked northeast, it crossed Old Port Gibson Road, Hankinson Road, and Moulder Road where it continued to snap or uproot numerous trees. The tornado finally lifted near Fisher Ferry Road in southern Warren County. A tornado debris signature was noted on radar during this tornado. The total path length of this tornado was 20.03 miles. The total path width was one half of a mile (880 yards) and the estimated maximum wind speed was 115 mph, both of which occurred in Claiborne 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 Grange Hall (32.1510, -90.8070).
