KERRVILLE, Texas (AP) — Multiple deaths have been reported in Texas after heavy rain caused flash flooding, while search teams used boats to conduct rescues Friday as fast-moving water threatened riverfront communities near wildlife habitats and campgrounds.

As much as 10 inches (25 centimeters) of heavy rain fell in just a few hours overnight in central Kerr County, causing flash flooding of the Guadalupe River.

Judge Rob Kelly, the chief elected official in the county, confirmed fatalities from the flooding and dozens of water rescues so far. He said he was advised not to cite specific numbers and said authorities are still working to identify those whose lives were lost.

“Most of them, we don’t know who they are,” Kelly said during a news conference. “One of them was completely naked, he didn’t have any ID on him at all. We’re trying to get the identity of these folks, but we don’t have it yet.”

Officials conducted dozens of rescues, and the emergency response continued as an unknown number or people remained unaccounted for, Kelly said.

A flood watch issued Thursday afternoon estimated isolated amounts up to 7 inches (17 centimeters) of rising water. That shifted to a flood warning for at least 30,000 people overnight.

When asked about the suddenness of the flash flooding overnight, Kelly said “we do not have a warning system” and that “we didn’t know this flood was coming,” even as local reporters pointed to the warnings and pushed him for answers about why more precautions weren’t taken.

“Rest assured, no one knew this kind of flood was coming,” he said. “We have floods all the time. This is the most dangerous river valley in the United States.”

Texas Gov. Greg Abbott said the state was providing resources to Hill Country communities dealing with the flooding, including in Kerrville, Ingram and Hunt.

“I urge Texans to heed guidance from state and local officials and monitor local forecasts to avoid driving into flooded areas,” Abbott said in a statement.

The Guadalupe’s river gauge at the unincorporated community of Hunt, where the river forks, recorded a 22 foot rise (6.7 meters) in just about two hours, according to Bob Fogarty, meteorologist with the National Weather Service’s Austin/San Antonio office. Fogarty said the gauge failed after recording a level of 29 and a half feet (9 meters).

“We think the river’s higher than that,” Fogarty said. “The gauge is completely underwater.”

The riverfront communities include several camps, wildlife habitats and campgrounds. Texas Game Wardens, part of the state parks and wildlife agency, said on Facebook that search and rescue teams are conducting rescues throughout the region and sending more boats to help.

“This is the kind of thing that will catch you unaware,” Fogarty said. “The water’s moving so fast, you’re not going to recognize how bad it is until it’s on top of you.”

New Jersey also sees deaths due to severe weather
Meanwhile, strong thunderstorms were being blamed for at least three deaths in central New Jersey, including two men in Plainfield who died after a tree fell onto a vehicle they were traveling in during the height of a storm there, according to a city Facebook post.

The men were ages 79 and 25, officials said. They were not immediately publicly identified.

“Our hearts are heavy today,” Mayor Adrian O. Mapp said in a statement. “This tragedy is a sobering reminder of the power of nature and the fragility of life.”

The city canceled its planned July Fourth parade, concert and fireworks show. Mapp said the “devastating” storms had left “deep scars and widespread damage” in the community of more than 54,000 people and it was a time to “regroup and focus all of our energy on recovery.”

Continuing power outages and downed trees were reported Friday throughout southern New England, where some communities received large amounts of hail. There were reports of cars skidding off the road in northeastern Connecticut.
