A stretch of chain-link fence along the Guadalupe River in the Texas town of Kerrville has become a focal point for the community's grief

In what experts call "Flash Flood Alley," the terrain reacts quickly to rainfall steep slopes, rocky ground, and narrow riverbeds leave little time for warning.

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.

The organizations working together to help the flood victims said that 'no additional in-kind donations (clothing, food, supplies) are needed in Kerrville.' They said the best way to help is with monetary donations.

With more than 170 still missing, communities must reconcile how to pick up the pieces around a waterway that remains both a wellspring and a looming menace.

President Donald Trump is visiting Texas on Friday to assess catastrophic flooding that has killed at least 120 people.

President Donald Trump toured the devastation left by flash flooding in central Texas amid growing questions about how local officials responded to the crisis as well as questions about the federal response -- including the fate of the Federal Emergency Management Agency -- that he has so far avoided.

Plans to develop a flood monitoring system in the Texas county hit hardest by deadly floods were scheduled to begin only a few weeks later.
