As early as July 2, officials at the Texas Division of Emergency Management, or TDEM, were publishing news releases warning that “heavy rainfall with the potential to cause flash flooding is anticipated across West Texas and the Hill Country” and readying resources, such as swift-water rescue boat squads.

At least 68 deaths—including the deaths of 21 children—have now been confirmed in the central Texas flash floods, according to the latest update from officials, though dozens of children from a summer camp remain unaccounted for as blame swirls over preparedness and whether residents were properly alerted.
