The death toll from flash floods in the US state of Texas has risen to 91, the White House said Monday.

"Moments ago, the Department of Homeland Security provided an update that 91 innocent souls have now perished," spokeswoman Karoline Leavitt told reporters.

Kerr County Sheriff Larry Leitha said Monday that his county saw 75 deaths due to the floods, including 48 adults and 27 children, with 15 of the adults and nine of the children as yet unidentified.

Ten girls who were attending Camp Mystic and one counselor there are still unaccounted for, according to Leitha.

Earlier in the day, the Christian summer camp announced that 27 campers and counselors had died in the floods.

Additional fatalities were reported across multiple counties, with seven deaths in Travis County, three in Burnet County, two each in Kendall and Williamson counties, and one in Tom Green County, CNN reported.

There is no immediate information available about the one person not included in the 91-person figure announced by Leavitt.

Leavitt: Weather service was well staffed

Leavitt also denied claims that the National Weather Service failed to provide adequate and timely warnings about the flooding.

“They gave out timely flash flood alerts. There were record-breaking lead times in the leadup to this catastrophe. There is ongoing flood monitoring, and these offices were well staffed,” she said.

The New York Times had earlier reported that a number of key positions at the National Weather Service were vacant due to Trump’s budget cuts since taking office, suggesting that these gaps might have hindered a prompt response to the emergency.

UN Secretary-General Antonio Guterres offered condolences for the floods through spokesman Stephane Dujarric. "The Secretary-General is deeply saddened by the tragic loss of life," he said.

"The Secretary-General extends his heartfelt condolences to the families of the victims and expresses his solidarity with all those impacted, the people of Texas and the government of the United States," Dujarric added.

US President Donald Trump said he plans to visit Texas later this week after signing a major disaster declaration for Kerr County to ensure first responders "immediately have the resources they need."

Leavitt said Trump's visit to Texas is "tentatively" planned for Friday. She said they are trying to find the "most appropriate time on the ground," adding: "We don't want to interrupt the recovery efforts."

The flooding began late Thursday and lasted into the early hours of Friday, as heavy rains engulfed the Guadalupe River, pushing it to a crest of more than 39 feet (11.8 meters), surpassing the region's second-largest modern flood, in 1987.
