Residents across the south are bracing for more severe weather.

A powerful storm system is moving eastward over Louisiana and Mississippi, damaging homes with powerful winds.

The same system hit the Dallas, Fort Worth area on Tuesday, leaving a devastating path of destruction.

Residents took cover as warning sirens rang out across the city. More than a dozen tornadoes touched down in the Dallas, Fort Worth area.

The National Weather Service called at least two of them "large and extremely dangerous."

One of these tornadoes sent 30,000-pound tractor trailers flying through the air, a view many drivers had as funnel clouds raced toward the highway.

"And the cars, they just shake and all I could say [was], 'Jesus, save me from this storm," one driver said.

In Forney, Texas, a grandmother is being called a heroine. She took cover in a bathtub with her grandson and two other children.

At one point, she clung to her grandson by his feet as the storm tried to rip him away.

Lindsey Enochs' mother says she saved her son.

"She saved his life. She stayed on him and the babies," Enochs said. "She babysits," she explained. "She had three of them in there; she kept them all alive," she said.

Today, as residents survey what's left of their homes, they say they're blessed to be alive.

"It was a miracle," Andy Jones said. "[It] lets you know the Lord knows what He's doing.""

Operation Blessing disaster teams are in the area today. Jody Gettys, director of  OB's disaster relief, said her teams will act as the hands and feet of Jesus Christ.

"So we'll be there whether it's serving a hot meal, helping people clean up their homes, [or] whatever the greatest need is, Operation Blessing will be there to help," Gettys said. 

Thousands of homes are still without power and the Red Cross estimates more than 650 homes are damaged. Miraculously, no deaths or serious injuries have been reported.
