Authorities said an unnamed 20-year-old driver died when his car hit a tree felled by the storms Thursday near Shreveport.
At least three tornadoes touched down in northwest Louisiana.
The storms blew the signature steeple off a church in downtown Shreveport. The falling tower hit a car and the 57-year-old driver, Michael Williams, had to be pulled out by rescuers. He suffered broken bones.
The storms brought heavy rain and at least two tornadoes in Arkansas, but there were no reports of injuries in that state. Roads were flooded in parts of southwest Arkansas.
