Damage was also reported in Kennedale and Arlington, Texas. The mayor of the latter city signed a disaster declaration to help cope with the destruction.
Tarrant County spokesman Mark Flake said about 40 homes in Arlington sustained moderate damage. The Cowboys football stadium emerged virtually unscathed, according to its general manager.
In Kennedale, a large water main broke and several people were injured, said city spokeswoman Amethyst Cirmo, though she could not immediately confirm how many. The city's police chief, however, said there were no reports of deaths or injuries thus far. A community center was opened to residents displaced by the storm.
Dallas County Sheriff Lupe Valdez said the area was hit by "a series of tornadoes" that inflicted heavy damage on some of the southern suburbs.
"Our officers are going to several locations right now," Valdez said. She said deputies were en route to some of the hardest hit areas to prevent looting, amid reports "that some of that has already started."
"We have our hands full. There are already a lot of situations where we have to go out and help," she said.
But all told, damage from the storm could have been much worse, said Dallas Mayor Mike Rawlings.
"The big headline is that we dodged a big bullet," he said. "We're saddened by the damage the system did, but we've got nobody that's dead and no significant injures. It really is a miracle."
A tornado watch remained in effect for parts of northeast Texas through Tuesday night.
