1 dead, more than 100 rescued in US floods TORRENTIAL rains have caused major flooding the San Antonio area leaving a person dead with more than 100 people rescued. A woman was swept out of her vehicle by floodwaters and her lifeless body was found beside a stream on Saturday. Rescue workers were searching for someone who was missing after being trapped in another car, city Fire Department spokesman Christian Bove said. "Our phone hasn't stopped ringing from early this morning," Bove said in a statement on CNN network, adding that his department has taken part in about 100 rescues since the downpours began on Friday night. According to weather reports, San Antonio and Austin were alerted on Friday to the cresting rivers and the risk of flooding. The San Antonio River reached record levels on Saturday of over 10.5 metres, while in October 1998 it reached just 9.75 metres, the US National Weather Service said. Numerous roads in several counties were closed on Saturday. San Antonio Mayor Julian Castro urged residents not to drive. The San Antonio River about 30km southeast of the city, near Elmendorf, was expected to peak at 18.6 metres by Sunday morning, well above the flood stage of 10.5 metres. The most devastating floods ever recorded in Texas occurred in 1998, the result of heavy rains and a column of humid air brought on by Hurricane Madeline, which lashed the west coast of Mexico. At that time a total of 11 people died in San Antonio, with material damage estimated at some $US750 million ($A773.44 million), according to a city report.
