Texas Gov. Greg Abbott signed an expanded emergency declaration that added Texas counties impacted by the disastrous flooding. The new declaration now includes Bexar, Burnet, Caldwell, Guadalupe, Travis and Williamson counties, Abbott said at a press conference Saturday afternoon.

"We will be relentless and going after and ensuring that we locate every single person who's been a victim of this flooding event. We're not going to stop today or tomorrow. We will stop when the job is completed," Abbott said.

Abbott also signed a request for a federal emergency declaration.

"Know that President Trump is absolutely heartbroken by what has happened here in Texas, and the loss of life is absolutely devastating to him and Melania," Homeland Security Secretary Kristi Noem said at the press conference.

Areas of heavy rain and the threat of dangerous flash flooding continues to impact parts of central Texas Saturday afternoon as the area recovers from Friday morning’s deadly flash flooding along the Guadalupe River.

For the second night in a row, another significant and dangerous flash flood event unfolded in the region. This time, about 100 miles northeast from yesterday’s catastrophic event.

A Flash Flood Emergency continues for much of Burnet County, Texas, as well as western parts of Williamson and Travis Counties until 4 p.m. CT.

Up to a foot of rain has fallen in this area triggering major flash flooding. There have been reports of numerous road closures in the area, according to the National Weather Service.

The flash flood threat will finally diminish Saturday night with all Flood Watches expiring between 7 to 10 p.m. CT, depending on location.

Kerr County Judge Rob Kelly was pressed by a reporter as to why evacuations didn't take place Thursday, but the judge said, "We didn't know this flood was coming." Officials said the county does not have a warning system on the river.

"We have floods all the time. This is the most dangerous river valley in the United States, and we deal with floods on a regular basis. When it rains, we get water. We had no reason to believe that this was going to be anything like what's happened here, none whatsoever," he said.

Rain continued to hit the region Saturday, prompting flash flood emergency warnings for much of Burnet County and western parts of Williamson County and Travis County.

President Donald Trump said his administration is working with state and local officials in Texas in response to the flooding that occurred on Friday, he said in a post on social media.

Trump also said that Secretary of Homeland Security Kristi Noem will arrive in Texas on Saturday in response to the flooding.

"Melania and I are praying for all of the families impacted by this horrible tragedy. Our Brave First Responders are on site doing what they do best," Trump said.
