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.

More than 2,100 searchers from a dozen Texas Counties, other states and Mexico are continuing recovery efforts to find more victims of the deadly flash flooding in central Texas.

The death toll in the July 4 Central Texas flooding rose to 103 on Friday as the search continued for those still missing.
