A line of severe weather that moved from Texas across southern Louisiana and into Mississippi brought severe rain and lightning as it swept through the region.
A tornado that touched down in western Louisiana damaged more than a dozen homes in a part of the state still struggling to recover from repeated weather disasters, officials said.
The National Weather Service said in a preliminary report posted on Twitter that an EF-2 tornado caused "significant structural damage" to about a dozen homes when it touched down around midday. Several other homes also received minor damage. Two people were injured; one woman was hurt when a window was blown into her home and a man was cut on his leg by flying debris, the weather service said.
