Thousands of people lost power and access to basic services as Hurricane Harvey caused widespread damage to the Texas coastline and the Southeast.
A major storm surge inundated many areas, and the National Weather Service issued warnings of flooding.
The National Weather Center said there could be up to 2 feet of flooding in some areas.
At least 3,000 people were rescued from homes and other structures in some of the hardest hit areas.
In Corpus Christi, officials said nearly 5,000 residents were rescued as rescuers attempted to pull out at least 1,500 people who were trapped in submerged homes.
More than a thousand people were treated at the scene of the storm, according to a National Weather Commission report.
