UVALDE, Texas (AP) — First responders in storm-battered Texas again rushed to save people trapped in high waters Friday, as more heavy rain widened the danger from floods that have killed at least two people and left hundreds more in need of rescuing.

A week of punishing downpours dumped more than 2 feet in some areas.

In all, roughly 6 million residents were under a flood watch at various points this week.

The rain was expected to taper off, but another round of showers worsened already swollen rivers and flooded rural communities near the border with Mexico that had largely been spared major damage.

Near Ozona, a small town about 200 miles west of San Antonio, floodwaters spilled over Interstate 10. More than 50 people were rescued by boat from flooded apartments and a water-logged RV park.

A section of a bridge also collapsed over the Nueces River in Uvalde County.

Nearly 1 trillion gallons of water fell on the three hardest-hit counties over three days — enough to fill 1.5 million Olympic-sized swimming pools or supply 11 million homes for a year.
