Nearly a quarter of Texas' population lives in areas covered by a federal disaster declaration as a result of Tropical Storm Harvey.
Gov. Greg Abbott says 18 counties are now covered by the disaster declaration approved by President Donald Trump. There are nearly 7 million people in those counties, including the nation's fourth-largest city of Houston. Texas has a population of 27.8 million.
Sinkhole opens on Texas highway amid heavy rains
Police say a sinkhole has opened on a Texas highway about 25 miles (40 kilometers) southwest of Houston as Tropical Storm Harvey dumps more rain on the region.
Rosenberg police on Sunday tweeted a photo of the gaping hole that spread across more than half of a two-lane highway — Farm-to-Market 762.
Water could be seen filling the sinkhole as pieces of highway asphalt hung from the edge of the damaged roadway.
Rosenberg police did not immediately provide additional details on the sinkhole, other than urging drivers to avoid the area. Police cars blocked off the highway.
