"We've got two tornadoes, one in Dallas and one in Arlington. I just watched it plow through a tractor trailer parking lot like it was Godzilla in a temper tantrum."
That's how NPR's Wade Goodwyn just described the images being shown on local television in Texas.
The images from WFAA, the local ABC affiliate in the Dallas-Fort Worth Metroplex, show tractor trailers flailing across the air in the middle of a dark debris ball.
Wade tells our Newscast unit that while in the tornado alley these kinds of occurrences are usual, people in the area still have a genuine respect for the power of tornadoes.
Quoting the weather service, the AP says there are already reports of "considerable damage."
We'll have more as this story develops.
