The flooding poses significant risks to both urban and rural areas. Roads, highways, and low-water crossings may become impassable, disrupting travel and potentially stranding vehicles. Urban areas like Austin and San Antonio face risks of overwhelmed drainage systems, while smaller waterways and creeks are rising rapidly, increasing the likelihood of flash flooding. Rural areas may experience overbank flooding, affecting farms and ranches. The NWS warns that conditions can change quickly, and nighttime flooding is particularly hazardous due to reduced visibility.
