A toddler and her mother were killed when a possible tornado flipped over a mobile home in Louisiana, authorities said on Sunday, as forecasters warned of a dangerous weather system that could bring hail and severe thunderstorms to parts of the U.S. South.

Neville Alexander, 3, and Francine Gotch, 38, were inside the mobile home in Breaux Bridge, outside Lafayette, when the storm slammed into the structure, causing "significant damage," the St. Martin Sheriff's Office said on its Facebook page.

Video posted on the page shows what appeared to be the remnants of a mobile home with its walls and roof collapsed and furniture and other household belongings upended and scattered. Nearby houses and vehicles appeared unscathed.

The National Weather Service issued a rare "high risk" advisory for areas in northern Louisiana and eastern Texas, warning residents about the threat of severe weather. St. Martin Parish is in south-central Louisiana.

The storm system, also a concern for far southern Arkansas, was expected to track into Mississippi into the evening.

"After dark, the threat shifts eastward," John Hart, a meteorologist at the National Weather Service's Storm Prediction Center in Oklahoma, said by phone.

He urged residents in the affected areas to pay close attention to forecasts and tornado warnings, noting that Monday could bring more severe weather conditions into Alabama.

The warning comes after a severe weather system killed at least 21 people in the South earlier this year, many in mobile homes demolished by tornadoes in Georgia and Mississippi.
