Severe thunderstorms and flooding rainfall are pounding a large portion of the central and southern United States Monday, including areas still recovering from destructive storms over the weekend.

The storms caused "extensive damage to residential and commercial properties," and knocked down power lines, traffic lights, and trees throughout the area, the fire department said. By Sunday night, more than 17,000 people were without power — down from the nearly 82,000 people left in the dark Sunday morning, according to poweroutage.us.

At least 11 people were injured after tornadoes tore through the Oklahoma City area overnight, emergency officials said on Sunday. In the hours that followed, the DFW area was put on notice for potential severe weather - and the Metroplex is bracing for possible storms tomorrow.
