A TV reporter helped to rescue a man who drove his car into a flooded underpass in Houston.
In the incident captured on video today, KTRK reporter Steve Campion yells, "Dude, you've got to get out of the car!" The man opens the passenger door and crawls out into the water as the reporter yells: "Leave the car! Swim!"
The driver swims toward Campion, who wades out into the waist-deep water and extends his hand.
As the car slowly sinks under water, the driver tells Campion that he's OK and that he didn't think the water was so deep.
More than 470 flights have been canceled in Houston after storms dumped about 16 inches of rain on the area.
