(CNN) — Flooding has left one person dead and another missing in San Antonio, Texas, authorities said Saturday.
The fatality occurred when a woman was swept from her vehicle, fire department spokesman Christian Bove told CNN. Her body was found along a creek, he said.
Bove said the department has been involved in at least 100 rescues since the flooding started.
"Our phone hasn't stopped ringing from early this morning," he added.
Torrential rains overnight continued into the morning, triggering flash flood warnings across South Texas.
On Saturday afternoon, San Antonio and Austin were under flash flood warnings and flood watches and warnings, CNN meteorologists said.
San Antonio International Airport received 9.57 inches of rain during Saturday morning alone, the meteorologists said.
Flood levels on the San Antonio River reached a new record Saturday at Loop 410 when water rose to 34.2 feet at 10 a.m. (11 a.m. ET) Saturday, said the National Weather Service in Austin/San Antonio. The previous record was 32.57 feet on October 17, 1998, the service said.
In an interview with CNN affiliate KENS, San Antonio resident Mary Alice Galicia described how water enveloped her house.
"It was underwater 20 minutes ago," she said. "I came over here. I own the property and my daughter said that she couldn't get to her car. Her car's all flooded. The property -- the water's all swarming through the whole house. I just came over to check to see what I could do, but there's nothing that I can do right now."
Galicia doesn't have flood insurance because she "never imagined this would happen," she said.
"But it's not stopping. I thought it was gonna stop," she said about the water damage.
