This image really got to me...Storm Harvey: Up to 2,000 rescued as Houston hit by 'catastrophic floods'
Up to 2,000 people have been rescued from floods in and around Houston, as Tropical Storm Harvey continues to batter Texas with heavy rains.
There are reports of possible deaths in submerged vehicles, but investigations continue, Chief Darryl Coleman of the Harris County Sheriff's Office said.
Amid catastrophic flooding, the National Weather Service (NWS) warned that conditions were "unprecedented".
Many shelters have been opened, including in a convention centre.
There is a "flash flood emergency" across the Houston Metro area, with travel near impossible, the NWS says.
It earlier noted reports of five deaths, but only one fatality in Houston has been confirmed.
Houston Mayor Sylvester Turner has urged residents not to call emergency services unless their situation is life-threatening and they need to be rescued.
"Don't get on the road. Don't assume this storm is over," he said.
