Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

President Donald Trump met with victims' families and surveyed the damage of catastrophic floods that struck the state one week ago.

Here are five key takeaways from the president's visit to Kerrville.

A United Cajun Navy commander leads flood recovery efforts in his hometown of Kerrville, Texas, where 121 people died in catastrophic flooding.

More than 170 people are still believed to be missing a week after the forceful floodwater hit over the July Fourth weekend.

The President and his allies have so far bristled at any suggestion that much could have been done to prevent the tragic loss of life in Texas. Trump described the flooding as a "once in every 200-year deal", even if he did suggest that "alarms" could have helped.

Officials in Kerr County, where the majority of the deaths from the July 4 flash floods occurred, have yet to detail what actions they took in the early hours of the disaster.

It’s hard to believe the devastation,' Trump said. 'Trees that are 100 years old just ripped out of the ground. I've never seen anything like this, and I've seen a lot of bad ones.'

With hundreds confirmed dead or still missing, questions remain about the local response to flood warnings. Meanwhile, lawmakers will weigh measures to mitigate future disasters.

"As the community begins to rebuild, we remain committed to standing beside them in the days and weeks to come."
