Torrential rains have brought more flooding to the Houston area as emergency officials urge motorists to stay home until the water recedes.
About 6 inches of rain fell across much of Harris County, including Houston, and more swamped suburbs west of the city.
Authorities warned motorists of more than a dozen areas of high water along highways. Fire officials said they've conducted about two-dozen water rescues Tuesday, mostly pulling drivers from their stranded cars.
Houston officials launched emergency operations early Tuesday following the heavy rain that began a day earlier. The National Weather Service has issued flash-flood warnings for the region.
The same storm system brought widespread flooding to San Antonio and other areas Monday.
