A line of thunderstorms passing across Warren County Friday night spawned an EF-1 tornado packing 90 mph winds that cut through the southern part of Vicksburg and the county before dissipating on the east side of U.S. 61 South, according to a National Weather Service report.

The report was the result of an examination of the area Saturday by a Weather Service storm survey team.

“It started about 7 miles south/southwest of Delta (La.), and it ended 7 miles south of Delta,” said meteorologist John Moore with the National West Service Office in Jackson. He said no property damage was reported.

According to the report, the twister began just west of the Mississippi River over a heavily wooded area, crossed the river and cut a 75-yard wide path before moving over Glass Road, where it broke logs and branches and few small trees were snapped. It reached its peak intensity as it crossed U.S. 61 South, where it damaged multiple trees before dissipating in a wooded area on the east side of the highway.

The line of storms that produced the tornado was the leading edge of a cold front that also stirred up high winds and dumped more than 2 inches of rain as it moved through the area Friday night and into early Saturday morning.

Warren County Sheriff Martin Pace said the storms produced 17 weather-related problems in the county, with trees falling and blocking roads and taking down power lines, and reports of water and mud on county roads. A tree fell on a house on Newitt Vick Drive during the storm, damaging the building.

At the height of the storm, Entergy reported 1,088 power outages scattered across the county, according to Entergy customer service representative Shelia McKinnis. Problem spots, she said, were in Bovina, along U.S. 61 South, and on Warriors Trail.

She said power was restored to about 647 customers by 10 p.m. Friday. Service was expected to be restored to the remaining customers by Saturday afternoon.

Inside the city, runoff from the heavy rain inundated several streets, and the rains caused some dirt slides on a section of North Washington between the Klondyke and the entrance to the Port of Vicksburg, North Ward Alderman Michael Mayfield said.

The rains also caused problems on North Washington Street, where box culverts along North Washington silted up, causing runoff to backup and flow across the road, leaving mud and debris.
