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

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.

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