UVALDE, Texas (AP) — Some parts of Texas remained under threat for dangerous flash flooding Friday as other areas saw water levels recede enough for cleanup efforts following days of punishing downpours blamed for the deaths of two people.The National Weather Service issued a flash flood emergency in the early morning for the city of Sonora in Sutton County, about 170 miles (274 kilometers) northwest of San Antonio.The local sheriff’s office used a boat to rescue one person and local officials were urging residents in low-lying areas along the Dry Devils River to evacuate as heavy rain fell, although the request was not mandatory, said Chief Deputy Jon Gann.“The water’s up to the top of the banks,” Gann said. “If we get any more, we’re going to be into homes.”Flash flood warnings were issued for several other counties in the Texas Hill Country, where many areas are still reeling from devastating floods a year ago. Flood warnings were in place through the weekend in many locations downstream from hard-hit areas, where rain was tapering off Friday. Some rivers were expected to reach historic levels.Some areas west of San Antonio have seen 2 feet (60 centimeters) or more of rain since the storms began on Tuesday. Rescuers aboard boats and helicopters have saved more than 200 people including stranded drivers and people trapped in homes, Gov. Gregg Abbott said.
