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.

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.
