Two women died Saturday -- one of them after being swept away moments after being inches from her would-be rescuers -- due to raging floodwaters in San Antonio, which braced for yet more drenching rains. At one point Saturday, a storm and subsequent floods had knocked out power to about 12,000 customers and spurred the closure of dozens of streets in the Texas city and the surrounding county, authorities were quoted as saying by CNN. Scores of people had to be evacuated due to floods and other issues, and Fire Chief Charles Hood noted there had been about 250 water-related calls -- in addition to ones for things like medical emergencies, accidents and more -- in the first 15 hours of Saturday. The greatest concern had to do with people getting too close to fast-moving, deceptive and unpredictable floodwaters.
