As ominous storm clouds gather once more over Texas, the desperate search for more than 150 individuals still missing since the catastrophic July 4 floods has now stretched into its second week.

A perfect storm of a slow-moving pocket of moist air, parched terrain and a hilly area prone to flash flooding unleashed absolute hell on Texas Hill Country — where more than 50 people have died, according to meteorologists.

The updates come after President Donald Trump and First Lady Melania Trump visited the region with other Texas officials on Friday.
