Authorities say a powerful storm peeled the roofs from buildings, toppled some trucks and blew down Oak trees and limbs in the Mobile area, leading to some road closures.

Mobile County Emergency Management Agency Director Ronnie Adair tells The Associated Press that the storm struck around or shortly before 5 a.m. Thursday.

Adair said there are several buildings in the Mobile area with roof damage after high winds peeled them off buildings. He said there were no immediate reports of any major injuries.

Adair said that some parked vehicles such as delivery trucks were overturned.

He said it wasn't known whether the damage was caused by a tornado, and that would be assessed later during daylight hours.

A tornado watch, scheduled to be in effect until noon Thursday, covered 28 Alabama counties
