Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

Nearly a week after floodwaters swept away more than 100 lives, Texas officials are facing heated questions over how much was – or was not – done in the early morning hours of Friday as a wall of water raced down the Guadalupe River.

At least 120 people have died and some 173 people remain unaccounted for statewide, nearly a week after flash floods ravaged the Texas Hill Country.
