Strong winds from a fast-moving storm system Friday night and early Saturday morning have left considerable damage in their wake in several parts of Arkansas.

At the University of Central Arkansas in Conway, several buildings incurred roof damage, with part of one roof landing on and crushing a vehicle.

In a social media post late Friday, the university reported roof damage to an all-female freshman dormitory, Carmichael Hall, prompted its evacuation with students being moved to the student center. No injuries were reported.

In Mountain Home in northern Arkansas, authorities evacuated a nursing home after the roof was severely damaged. Police say no injuries were reported.

Across Arkansas, winds snapped tree limbs and utility poles and downed power lines.

A tornado has ripped through a tiny town in the Ozark Mountains of northwestern Arkansas, injuring at least four people.

The twister struck Mountainburg at about 4 p.m. Friday as a line of severe thunderstorms rumbled across eastern Oklahoma and western Arkansas.

Crawford County Emergency Management Director Brad Thomas said there were at least three entrapments as the tornado moved through the town of 624 residents about 20 miles northeast of Fort Smith. He said at least four people were taken to hospitals, but he didn't know their conditions.

Video from the scene showed uprooted trees, overturned cars, damaged buildings and downed power lines.

Several tornado warnings were also reported across Southeast Arkansas, though no significant damage was reported.
