UVALDE, Texas (AP) — Rescuers saved dozens of stranded drivers and people trapped in homes from catastrophic flooding in Texas while many more fled to higher ground Thursday across a region still recovering from devastating floods just a year ago.

So far, at least one person has died, said Gov. Greg Abbott, who added that it appeared that many of summer camps hit hard last year were not facing any danger. “Our number one focus is saving lives,” he said.

After days of pounding rain, the National Weather Service said a “large and deadly flood wave” was barreling down the same river wrecked by flash floods last summer when two dozen children and counselors were killed at Camp Mystic.

Forecasters urgently warned “Move to higher ground now!” as rivers rose hour by hour, turning them into fast-moving seas of white water. Several tornado warnings were also issued.

The Texas Hill Country floods over the July Fourth holiday last year killed more than 100 people.

The governor said there was “one loss of life” so far but did not specify where or when. More than 1,300 personnel were responding and have rescued well over 70 people, he said Thursday.

The unfolding crisis brought back haunting memories of last summer's unimaginable floods for many.

“It’s crazy happening two times in one year,” said Josiah Rodriguez, who woke to the sound of heavy rain around 2 a.m. Thursday in Kerrville. He navigated flooded roads to help evacuate relatives.

“Last year there was no warning of it,” he said. “It just kind of happened overnight and it took everyone by surprise. This year, a lot more alerts have gone into place, a lot more safety measures.”

Residents said they were caught off guard a year ago and didn’t receive any warning when floods overtopped the Guadalupe River. Some local leaders were criticized for not acting quickly.

The storms and flooding this time threatened multiple counties close to the border with Mexico and in the Texas Hill Country near San Antonio. City officials in Kerrville urged people to shelter at the highest levels of their homes.

Images along a creek in Kerr County showed propane tanks that had been pushed onto a bridge and a mess of tangled trees.

Uvalde residents isolated by floodwaters

Floodwaters overran the city of Uvalde overnight, cutting off outside access. The Leona River, normally dry most of the year, filled streets with water.

“People really can’t get anywhere” said Carmen Rodriguez, who was nervously watching water engulf her neighborhood Thursday morning as a helicopter roared overhead. “We have a place to go, but all the streets are closed.”

Phones buzzed with warnings throughout the night warning of flash floods in the morning. Rodriguez said it seemed that authorities were well prepared. By Wednesday, Uvalde police had ordered some mandatory evacuations, with first responders notifying people directly.

Uvalde officials sent out rescue boats and found multiple people trapped in vehicles overnight, said Juli Alvarado, a spokesperson for Uvalde police.

“There’s no way into the city at this point,” she said.

Texas Game Wardens rescued more than 40 people and evacuated about a dozen others, mostly in the Uvalde County area, according to a Texas Parks and Wildlife Department spokesperson.

Flooding could reach last year's deadly high

The floodwaters were expected to reach a crest similar to last year's flood, the weather service said.

Gauges in some spots along the Guadalupe River showed it rose by more than 30 feet (9 meters) in just hours overnight. One gauge outside Kerrville showed the river had risen 32 feet (9.7 meters) in four hours.

Close to Camp Mystic, which remains shut, the Guadalupe River near Hunt reached about 20.5 feet (6.3 meters), according to a U.S. Geological Survey gauge, which is just under the level expected to inundate structures and roads.

Flooding hits towns still rebuilding

Volunteer firefighters spent the night helping people evacuate their homes and answering calls about rising water in Ingram, just up river from Hunt, where summer camps dot the shores of the Guadalupe, Ingram Mayor Claud Jordan said Thursday morning.

While the water didn’t rise as high as a year ago, he believes this round of flooding was more widespread and “worse” in his city. “The rural part of Ingram, all the roads are just trashed,” he said.

“There are a bunch of businesses that haven’t reopened from last year. They’re still trying to rebuild from the July 4 floods,” Jordan said. “This doesn’t help.”

A rush to higher ground

Residents at an RV park in Comfort, Texas, near the Guadalupe River moved their trailers as local fire department sirens sounded, manager Duke Earwood said Thursday.

Water rose over the hoods of vehicles parked closest to the river.

While the water started to recede, another surge was expected, Earwood said at the Comfort RV Resort, which has about 200 residents. “People need to know to just kind of stay put for now,” he said.

Markers showed the flooding already matched the level from the big flood last July.

“Too familiar for sure, and too soon,” Earwood said.

Another test for Texas Hill Country after the Camp Mystic disaster

The Texas Hill Country is especially prone to flash floods because the area’s signature limestone is covered by just a thin layer of soil. During heavy rains, water can quickly shoot downhill before quickly filling the narrow river basins.

The weather service said 10 to 20 inches of rain (25 to 50 centimeters) had fallen in the past two days, with 8 inches (20 centimeters) in just two hours early Thursday.

The deluge dumped nearly a foot of rain in some counties and put people in multiple counties under flood watches, with some were expected to remain in effect through Friday evening.

The governor issued disaster declarations for dozens of counties. As of late Wednesday, six million residents in 57 counties were under a National Weather Service flood watch.
