The remnants of Tropical Storm Bill, now a tropical depression, churned through the saturated state of Texas on Wednesday, knocking out power to at least 25,000 people and flooding roads around Dallas and Houston.
The storm made landfall just before midnight at Matagorda Island, north of Corpus Christi, and was soon downgraded to a depression.
Flash flood watches were posted across the eastern half of the state. The city of Ganado, outside Houston, picked up 11.8 inches of rain, and El Campo got 11.6 inches, The Weather Channel reported.
In and around Dallas, authorities closed at least eight roads because of flooding, and more than 600 flights were canceled into and out of Dallas-Fort Worth International Airport.
Flooding was also reported in Houston, where part of Interstate 59 was closed because of standing water, and Fort Worth.
The storm, with a signature counter-clockwise rotation, was headed north into Oklahoma. Southern cities and towns in that state had picked up 2 inches of rain by early afternoon and were expecting more.
In Texas, authorities kept an eye on rivers and worried about the coming days. The flood risk is high because of record rain that pounded the state last month.
The Brazos River, outside Houston, was at 32 feet on Wednesday and could swell past its flood stage to 50 feet by Sunday. The Red River, which divides Texas and Oklahoma, was at 25 feet but could swell to 37 feet in coming days.
