The deadly July 4 flash floods in Texas have prompted a lot of questions and soul-searching: about the failures of early-warning systems, the Trump administration’s cuts to the National Weather Service and disaster programs and the vulnerability of communities around the country to disasters worsened by climate change.

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.

At several points during the hearing, the state emergency management chief directed attention to the role of local emergency managers in disaster response.
