JACKSON, Miss. (AP) — The National Weather Service has confirmed that at least four tornadoes were part of the storm system that raked northern and central Mississippi on Wednesday night and Thursday morning.

The biggest of the four storms was a twister that traveled 16 miles from Scott into Newton counties east of Jackson. With a half-mile-wide damage path, it was rated EF-3 on the Fujita scale, with peak winds estimated at 140 mph. That storm blew down trees as well as three electrical transmission towers. One person was injured when a tree fell through a roof.

Authorities said Thursday that at least seven people were injured when a line of storms pushed across the state.

Severe roof damage to the Greenville-Weston High School campuses closed Greenville schools at least until Monday.
