The Houston area is threatened with even more flooding as another round of storms target Texas this weekend.
Hundreds of people have already been rescued from homes, rooftops and roads due to earlier flooding.
The Harris County Joint Information Center told KPRC-TV that 196 people and 108 animals have been rescued by emergency response agencies in just that one county.
In neighboring Montgomery County, Judge Mark Keough told the Associated Press there had been more high-water rescues than he was able to count.
Evacuation orders were in effect for several areas.
Houston Mayor John Whitmire told citizens that police will be actively protecting the evacuated areas from criminal activity.
"Do not allow your property, possessions to keep you at home," Whitmire said. The National Weather Service warns that the potential exists for heavy rainfall that could result in flash flooding. The storms could bring hail and strong gusts and an additional 1-3 inches of rain.
Parts of Texas have seen a large amount of rain in the past five days, with Cotton Bayou in Chambers County receiving more than 15 inches.
Cedar Bayou in Harris County had more than 12 inches of rain.
Harris County Judge Lina Hidalgo described the predicted surge of water as "catastrophic."
Eighty-nine counties are under a disaster declaration because of flooding.
"As flooding conditions and severe weather continue in multiple regions across Texas it is important to remain weather-aware, follow the guidance of state and local officials, and avoid traveling in dangerous flood conditions," said Texas Gov. Greg Abbott.
No deaths or injuries were initially reported.
A Flood Watch remains in effect through Sunday afternoon.
