Severe storms and tornadoes along the U.S. Gulf Coast killed at least three people and injured 30 on Tuesday, destroying buildings and other structures across several states.
Two people died in Louisiana when a storm hit their mobile home park in St. James Parish, 50 miles (80 kilometers) west of New Orleans, said parish government personnel manager Libby Hotard.
The region was among the worst hit. "Some areas are totally devastated," Hotard told AFP.
A man who lived near the mobile home park told local television station WVUE that he was asleep when he heard a "big rumbling sound and the whole entire house started shaking."
Video broadcast on local television showed mobile homes completely destroyed by the storms.
Emergency services transported 30 injured to local hospitals, Hotard said. Rescuers were conducting search and rescue operations.

There were no reports of other deaths or injuries in the area.
The National Weather Service said a tornado hit southern Mississippi and that officials were tracking reports of other possible tornadoes in the region.
