President Donald Trump, accompanied by First Lady Melania Trump, visited Texas Friday to survey the results of last weekend’s flash floods that left more than 100 dead, and at least that number still missing.

Drainages through the Texas hill country filled with water 20 and even 30 feet deep in a matter of minutes after a deluge estimated at 10 inches to a foot of rain fell in a matter of hours.

Dozens of victims were from Camp Mystic, a Christian camp for girls along the banks of the Guadalupe River, which rose from a depth of about a foot to an estimated 34 feet in the dark.

Cabins, homes, cars, people all were swept away.

The victims include at least 36 children in a county that had declined to install early-warning monitors after failing to secure state funding.

Trump expressed support for a new effort to take on that project.

Reuters reported he said, “After having seen this horrible event, I would imagine you’d put alarms up in some form.”

Melania Trump promises prayers for the families hit so hard.

“My deepest sympathy to all of the parents who lost beautiful young souls,” she said. “We are grieving with you. Our nation is grieving with you. We just met with the wonderful families.”

The president said, “The first lady and I are here in Texas to express the love and support, and the anguish of our entire nation, in the aftermath of this really horrific and deadly flood.”
