President Donald Trump is expected in Texas Friday to visit areas impacted by floods last week that have left more than 100 people dead.

Historic Texas flood leaves 161 missing and 96 dead. Rescuers battle harsh conditions, as communities grapple with heartache and aid reaches survivors.

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.

At a Wednesday morning press conference, Kerr County Sheriff Larry Leitha declined to answer a question about delayed emergency alerts, saying that an "after-action" would follow the search and rescue efforts. "Those questions are gonna be answered," he added.

The Houston Texans were the first to announce their donations on Saturday, July 5, with more coming throughout the week. The Dallas Cowboys and the NFL Foundation joined the Texans on Sunday, July 6, with each contributing $500,000 in a $1.5 million total donation.

The grim task of searching for the scores of people missing from the devastating flood that struck Texas Hill Country nearly a week ago is taking an agonizing toll on searchers.

Crews are using construction equipment to clear vehicles, trees and homes in a race to locate the 161 people still missing since Friday’s devastating flood.

Over the last decade, an array of local and state agencies have missed opportunities to fund a flood warning system intended to avert the type of disaster that swept away dozens in Kerr County, Texas.
