The river grew by the size of a two-story building in less than an hour on Friday. One survivor described a “pitch-black wall of death.”

The downpours that swept away a children's summer camp and wreaked deadly havoc on huge areas of Texas caught holidaymakers by surprise. As the death toll passes 90 people, questions are being raised about whether adequate flood warnings were provided and why people weren't evacuated ahead of the deluge.

At least 104 people are confirmed dead following catastrophic flash flooding that tore through Central Texas last week, with dozens more still missing — a toll that continues to rise as communities grieve and remember those who were lost.

Central Texas was ravaged by floods over the July 4th weekend leading to deaths, including children at Camp Mystic, an all-girls summer camp.
