ToplineAt least 59 deaths—including the deaths of 15 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.

Anguished parents waited for word on the 11 young campers still missing from Camp Mystic, which was hit hard by floodwaters.

DHS Secretary Kristi Noem addressed the deadly Texas flood, promising to upgrade "ancient" National Weather Service systems for better early warnings.
