With hundreds confirmed dead, questions remain about the local response to flood warnings. Meanwhile, lawmakers will weigh measures to mitigate future disasters.

Testimony will be heard from those in charge of managing rivers as well as emergency managers and first responders about the flash flooding that killed at least 135 people.

Officials in Kerr County say that the body of a missing flood victim has been found, leaving only two people missing after the July 4 flood.

Republican Gov. Greg Abbott and county authorities have largely evaded questions about local officials' actions in the hours before disaster struck.

The severity of the flash flooding that killed more than 130 people in Texas's Hill Country was difficult to predict because the science is not yet available, a local meteorologist testified during Wednesday's special legislative session.

A man and a little girl from Camp Mystic were still missing, Abbott said. He last said the death toll stood at 135.

Two weeks after deadly floods swept through Texas, officials dropped the number of still-missing people in the hardest-hit area to three — down from nearly 160 in the days following the July Fourth weekend floods.

Nim Kidd, chief of the Texas Division of Emergency Management and representatives from the Upper Guadalupe River Authority are expected to testify.

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.

New flood warnings have been issued along the Guadalupe River in Texas less than two weeks after flooding killed more than 100 people.

As contaminated Guadalupe River water receded following the deadly flooding in Kerrville, Texas, this month, residents returned to find their homes, vehicles and businesses destroyed.

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.
