Apparent tornado brushes through Tupelo, Mississippi

(CNN) - An apparent tornado swept through parts of Tupelo, Mississippi, on Thursday, damaging trees and power lines, and overturning a 18-wheel truck, a law enforcement official told CNN.

"Just a little earlier this morning, we began to get reports of damage starting from the west side of Tupelo," said Chief Deputy John Hall, of the Lee County Sheriff's Department. The storm moved across the city to the north by the Mall at Barnes Crossing, he said.

Near there, on U.S. Highway 45, an 18-wheel truck was overturned, he said. There were no reports of injuries.
