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.

The death toll from the July 4th weekend flooding in Central Texas has risen to at least 110. In Kerr County alone, 161 people remain missing.
