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.

161. That’s the estimated number of people missing in Kerr County, Abbott said Tuesday. At least 10 people are missing in Travis County, while local officials have recovered who they believe to be the “last victim” in Williamson County, according to Texas Department of Public Safety Col. Freeman Martin.
