For the third straight day, thunderstorms have posed what meteorologists call life-threatening conditions in the Hill Country, where flooding earlier this month killed at least 131 people.

Many questions remain about how storms caught off guard an area prone to flooding and led to the second deadliest flood in Texas history. Here’s what we know. Flooding death toll increases to 132;

In the early days of July, pieces of weather systems were converging to create a disaster over Texas Hill Country that would transform the Guadalupe River into a monster raging out of its banks in the pre-dawn hours of July 4, claiming the lives of more than 129 people. At least 160 are still missing.

While the rain bomb that impacted Kerr County, devastating the lives of so many people, cannot yet be attributed to climate change, the physics is undeniable that a hotter atmosphere holds more water vapor and that when the rains come, they are much more intense.

The flood watch, in effect until 7 p.m. Sunday, applies to Bexar, Blanco, Burnet, Gillespie, Hays, Kerr, Llano, Travis and Williamson counties.

Michael Coen, chief of staff of FEMA under former presidents Barack Obama and Joe Biden, called on the state to be more proactive in preparing for disasters.

Texas officials and Hill Country leaders knew the risks of flooding along the Guadalupe. Warnings went unheeded, flood warnings, river gauges and sirens unfunded - and more than 130 Texans died.

"No more excuses," says the creator of a petition seeking a new early warning siren system for floods, tornadoes and life-threatening emergencies.

Lt. Gov. Dan Patrick and Speaker Dustin Burrows have assembled a select committee to take up a warning system after the deadly July 4 flood.
