Texas flooding updates: Over 130 dead as flash flood threat increases in Texas

A flood watch is in effect through 7 p.m. on Monday for areas in the Texas Hill Country, including Kerr County, Burnet, Austin and San Antonio.

Storms are forecast to be isolated and some areas will likely see nothing, while others may see heavy rain in short periods.

Locally, 2 to 4 inches of rain are possible, with the National Weather Service saying up to 10 inches are possible in the most extreme cases. Near-term models are not indicating a repeat of rains that led to the July 4 or July 5 deadly floods.

More rain is possible on Wednesday, with the rest of the week remaining dry for Hill Country.

At least 80 people have died in Texas as a result of the catastrophic flooding in the state. The death toll continues to rise as officials in affected areas conduct search and rescue operations.

By far the greatest number of fatalities occurred in Kerr County, where at least 68 people are believed to be dead, according to officials.

Deaths were also reported in Travis County, Williamson County, Burnet County and Tom Green County.

Officials in Kerr County, Texas, said in an update on Sunday that search and rescue operations are continuing as additional rain impacts already flood-hit areas.

"There was additional rain in the upper Guadalupe basin this afternoon, leading to a rise in Johnson Creek," the Kerr County Sheriff's Office wrote in a post on Facebook.

The agency said the additional rainfall may lead to a rise of one to two feet downstream when it enters the Guadalupe River in Ingram.

"Please be aware if you are near the Guadalupe River or Johnson Creek," the sheriff's office said.

Speaking with reporters before boarding Air Force One on Sunday, President Donald Trump spoke about the flooding in Texas, saying he'll "probably" visit the state on Friday.

"We're working very close with representatives from Texas, and it's a horrible thing that took place, absolutely horrible," Trump said, saying he's spoken with Texas Gov. Greg Abbott.

Asked if the meteorologists at the National Weather Service who were impacted by the federal cuts should be hired back, Trump initially said he didn’t know but eventually said no.

Trump also wouldn't answer if he was working on plans to phase out the Federal Emergency Management Agency (FEMA), as internal documents show the agency isn't properly staffed.

“Well, FEMA is something we can talk about later, but right now they're busy working, so we'll leave it at that," the president said.
