FORT WORTH (CBSDFW.COM) – A powerful line of thunderstorms continues to move east across North Texas.

The main threat has been and will be strong winds, up to 70 mph. The wind are powerful enough to do significant damage to trees, roofs, and power lines.

Lightning has and will be quite prolific as well…possibly triggering a few power outages along the way. As of 3:30 p.m. officials at Oncor confirmed to CBS 11 News that some 16,200 North Texas residents are without power.

The CBS 11 Storm Team has received reports of  cars blown off the road near Stephenville as the storms rolled through.

Expect the line of storms to sweep over most of the area during the afternoon and evening.

Cooke County Emergency Management Director Ray Fletcher tells CBS 11 News that six homes, in the Lake Kiowa area – about 10 miles southeast of Gainesville, have roof or structural damage. High winds there caused an 18-wheeler to flip over. The driver was taken to Denton Hospital and is expected to be okay.

There are reports that Wise County has been hit by straight line winds. “Well it’s strong enough to blow a mobile home off its foundation,” said Wise County Fire Marshal Mark Dodd. “It’s strong enough to cause all the damage that’s been reported.”

Near Decatur six recreational vehicles, at the Smith RV Center, were damaged.

There have been no reports of injuries in any North Texas city or town.

As to how flights at DFW Airport are being affected, American Airlines spokesman Ed Martelle spoke with KRLD NewsRadio 1080.

In the wake of the storms there has also been minor flooding is occurring. Everyone should take caution in lower-lying areas and near creeks or streams.

As it stands, the storms are expected to end by the evening hours, but another round of thunderstorms is in the forecast for Thursday, over parts of North Texas.
