Authorities say flooding in San Antonio has killed at least two people, and they are searching for a third person who was swept away in a creek.

San Antonio Fire Department spokesman Christian Bove says two women were killed in separate incidents Saturday after becoming trapped in their cars. Emergency crews recovered both of their bodies.

In the suburb of Schertz, authorities are still looking for a teenage boy who was swept away while trying to cross the swollen Cibolo Creek.

Torrential rains swamped San Antonio with flash floods on Saturday. Emergency workers used boats as they rushed to rescue more than 200 residents stranded in cars and homes.

More rain is forecast for overnight.
