Unfounded rumors linking an extreme weather event to human attempts at weather modification are again spreading on social media. It is not plausible that available weather modification techniques caused or influenced the July 4 flash flooding along the Guadalupe River in Texas.

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.

Officials in Texas are facing mounting questions about whether they did enough to get people out of harm’s way before a flash flood swept down the Guadalupe River.

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.

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.

The State Flood Plan, published last year, identified $54 billion in flood mitigation, warning and data needs. The state has awarded around $660 million since the plan was published, with a special legislative session coming soon.

From mud where vegetation once grew to debris scattered everywhere — see how one Texas camp is bouncing back from the Guadalupe River floods.

A flood watch is in effect into July 15 for more than a dozen counties as saturated ground gets drenched again.
