Hundreds of rescuers have been deployed to search for people missing in central Texas, after flash floods killed 51 people, including 15 children.
The worst affected area is Kerr County where 43 people havedied and where 27 children remain missing from a Christian youth camp located along the River Guadalupe.
“The work continues, and will continue, until everyone is found,” promised Larry Leitha, the sheriff of Kerr County.
People have also been confirmed dead in other parts of the state, including Travis County and Tom Green County.
Multiple flash flood warnings remain in place over the weekend in central Texas.
About 850 people have been rescued so far.
At a news conference on Saturday afternoon, Texas Governor Greg Abbott said he had signed an expanded disaster declaration to boost search efforts.
He said officials would be relentless in ensuring they locate “every single person who’s been a victim of this event”, adding that “we will stop when the job is completed”.
It remains a search and rescue mission, officials said, not a recovery effort.
They said rescuers were going up and down the Guadalupe River to try to find people who may have been swept away by the floods.
US President Donald Trump said his administration was working closely with local authorities to respond to the emergency.
Watch: Texans face flood aftermath
Forecasters have warned that central Texas may see more flooding this weekend.
The National Weather Service (NWS) said the area could see 2 to 5in (5cm to 12cm) of rain on Saturday.
Up to 10in of rain was possible in some areas badly affected by Friday’s deluge.
Much of the rescue has focused on a large all-girls’ Christian summer camp called Camp Mystic, located along the banks of the Guadalupe River.
Texas Lieutenant Governor Dan Patrick told the BBC’s Radio 4 PM programme many of 27 missing girls were “under the age of 12”.
Pictures from the camp show it in disarray, with blankets, mattresses, teddy bears and other belongings caked in mud.
Many were asleep when the river rose more than 26ft (8m) in less than an hour in the early hours of Friday.
In an email to parents of the roughly 750 campers, Camp Mystic said that if they had not been contacted directly, their child had been accounted for.

More details of those who died have started to emerge – some were as young as eight. It has also been confirmed sisters Blair and Brooke Harber, who were 13 and 11, are among the dead.
A special Mass will be held at Notre Dame Catholic Church on Sunday for those who died or are missing, and their families.

Scores of campers holidaying during the Independence Day weekend, were also unaccounted for.
Lorena Guillen, whose home and restaurant were destroyed, had 28 holidaymakers’ cars staying on her land near the river. She told the BBC News Channel that she heard screams from a family of five.
“They were getting washed away,” Guillen said. “They were clinging on trees to be rescued. But the rescuers couldn’t get to them.”
‘It could have been me’
Rachel Reed drove five hours from Dallas to pick up her daughter. She told the BBC that members of her Church and children’s school district were among the girls dead and missing.
“The families of those campers are living every parent’s worst nightmare,” she said. “Of course, it could have been me.”
Others started returning to the flooded areas.
Jonathan and Brittany Rojas visited their relatives’ home – where only the foundation remained.
They told the BBC that the mother and a baby of the family remained missing. A teenage son, Leo, survived after he became snared in barbed wire.
Another resident, Anthony, found his apartment full of mud and debris. His belongings were not salvageable, except a box holding childhood photos and his baby blanket.
“I lost everything I own,” he told the BBC. “Now I’m trying to figure things out.”

Four girls missing from a summer camp were found dead as a desperate search for dozens of other campers continues after devastating floods hit Texas, killing at least 51.
At least 15 children were killed as a result of what Texas GOP Congressman Chip Roy called a “once-in-a-century flood.” More than 850 people from around the region have been rescued or evacuated, officials said Saturday.
Two girls — 13-year-old Blair and 11-year-old Brooke — were among those killed by the floods, their father told CNN on Saturday night. Harber said Blair “was a gifted student and had a generous, kind heart,” and described Brooke as “like a light in any room, people gravitated to her and she made them laugh and enjoy the moment.”
There are also 27 girls still missing from Camp Mystic, an all-girls Christian summer camp along the Guadalupe River that was ravaged by the floods, officials said. At least four girls who attended Camp Mystic have been confirmed dead, according to reports, marking a tragic end to a day-long search.
The unexpected flash flooding struck on Friday after torrential rain along the Guadalupe River. The destructive force of the fast-rising waters just before dawn on Friday washed out homes and swept away vehicles.
