Residents in San Antonio were recovering after a month's worth of rain swamped parts of the city, trapping drivers, triggering treacherous water rescues, and leaving more than a dozen people dead.

The San Antonio Fire Department told CBS News on Saturday that 13 people have been found dead after flooding on highways in Texas.

At least six inches of rain fell in a three-hour period on Thursday, leading to more than a dozen vehicles being washed into a creek. A candlelight vigil was scheduled for Wednesday evening for the victims by the nonprofit San Antonio Aware and Prepared.
