Emergency crews suspended their search for victims of catastrophic flooding in central Texas on Sunday morning amid new warnings that additional rain would again cause waterways to surge.It was the first time a new round of severe weather has paused the search since the flooding earlier this month.

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.
