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.

The high-volume rainfall has killed dozens of people, while others remain missing and displaced. More than 850 people have been rescued in the last 36 hours, with search crews using helicopters, boats, and drones to locate victims and rescue people stranded in trees and isolated camps.
