Over the weekend the New York Times, citing a union official, reported that the nearby NWS office in San Antonio lacked a senior hydrologist, staff forecaster, and meteorologist.

It also reported that officials were concerned about the flood risk but rejected installing a warning system, saying it was too costly.

The disaster at the Camp Mystic summer camp has captured the nation's attention, with at least 27 children and counselors killed and others still missing.

The camp, a private Christian site founded in 1926, was accommodating more than 750 children when the floods struck after heavy rainfall.

"Our hearts are broken alongside our families that are enduring this unimaginable tragedy. We are praying for them constantly," the camp said in a statement.

"We have been in communication with local and state authorities who are tirelessly deploying extensive resources to search for our missing girls," the statement added.

The heavy flooding on Friday morning took many people by surprise, as holidaymakers camped out in rural areas by rivers over the July 4 long weekend.

Local officials say more than 850 people were rescued unharmed from the area near the summer camp, while eight people were injured. Some had to climb trees to save themselves from being swept away by the floods.
