KERRVILLE, Texas (AP) — Hope of finding survivors of the catastrophic flooding in Texas dimmed Tuesday, a day after the death toll surpassed 100, and crews kept up the search for people missing in the aftermath.

Local officials have faced angry questions about whether they could have warned people of dangerous flash floods in Texas Hill Country sooner. Rescue teams from neighboring states and Mexico have joined local efforts to search for survivors,

First responders struggled with difficult terrain as they continued search and recovery efforts. Officials have confirmed at least 106 people died in the Hill Country region, including 30 children and 56 adults in Kerr County.

Texas Governor Greg Abbott said Tuesday that many of those who are not accounted for were staying in state’s Hill Country but did not register at a camp or hotel.

The loss of life is unimaginable. While we are still grappling with what happened, it’s important to understand the historic nature of this flood. It likely already ranks as the third-deadliest flood in Texas history.

During a press conference with officials of Kerr County, Texas, reporters asked tough questions about the handling of the flood emergency system.
