Several more inches of rain were expected through the weekend in already soaked Texas and Oklahoma.
The death toll continues to rise in flood-ravaged Texas and Oklahoma and as receding floodwaters revealed mounting destruction, rains continue to threaten even more flooding on Wednesday.
In hard-hit Houston, some of that destruction came Tuesday in the form of a waste water treatment plant so inundated with waters from an overflowing nearby bayou that more than 100,000 gallons of raw sewage spilled out into surrounding floodwaters.
Flash flood warnings were expected through the weekend in Texas, as a storm system that has settled along several southern states brings several more inches of rain.
Hundreds of people were ordered to evacuate flood-threatened areas of Texas on Wednesday as storms bringing torrential rains battered the state, where at least 15 people have been killed in weather-related incidents this week, including six in Houston.
People were told to stay away from more than 200 homes in Parker County where the Brazos River was poised to spill its banks about 30 miles west of Fort Worth on Wednesday night, county officials said.
