Bexar County and the San Antonio metro face moderate but real disaster risk, primarily from flash flooding driven by the region's limestone terrain and intense thunderstorms. The Edwards Plateau geography channels runoff rapidly into urban streams, creating dangerous flood conditions with little warning.
