In the early days of July, pieces of weather systems were converging to create a disaster over Texas Hill Country that would transform the Guadalupe River into a monster raging out of its banks in the pre-dawn hours of July 4, claiming the lives of more than 129 people. At least 160 are still missing.

With the death toll from the catastrophic floods in the Texas Hill Country now topping 130 people, heavy rain further complicated the search for the missing. It comes as NBC News has learned new details about the response at Camp Mystic as floodwaters were rising.
