The risk of the catastrophic flooding that struck Texas Hill Country as people slept on July 4 and left at least 120 dead was potentially underestimated by federal authorities, according to an ABC News analysis of Federal Emergency Management Agency data, satellite imagery and risk modeling.

Nearly a week after deadly floods struck Central Texas, search and rescue teams are continuing to probe debris for those still missing.

Kerr County officials say death toll has risen to 96 due to the Hill Country floods, including 60 adults and 36 children.
