A study puts the spotlight on Texas as the leading U.S. state by far for flood-related deaths, with more than 1,000 of them from 1959 to 2019.

Here's what to know about the deadly flooding, the colossal weather system that drove it and ongoing efforts to identify victims.

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.

By Trevor Hunnicutt and Maria Alejandra CardonaKERRVILLE, Texas (Reuters) -President Donald Trump defended the state and federal response to deadly flash flooding in Texas on Friday as he visited the stricken Hill Country region,

Scholars and designers of early warning systems say that there are still huge gaps in our ability to predict flash floods and warn those at risk.

"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," Trump said as he spoke at a roundtable event with first responders and local officials.

The U.S. President traveled to central Texas to survey damage from the July 4 flash flood that killed at least 120 people.

The threat of heavy rain is “slight” for this weekend, but with the ground fully saturated in Kerr County even small amounts of rainfall could cause flooding.

Malaya Grace Hammond is among the latest fatalities identified from the Texas floods. Hammond's family said she was swept away by floodwaters on Saturday in Travis County.
