Officials warned that the full extent of the catastrophe is unknown and unaccounted victims could still be found amid the massive piles of debris.

The flash floods are shaping up to be one of the deadliest disasters in modern Texas history, nearing the fatality figures of Hurricane Rita, which unleashed a torrent of wind and rain on Texas in 2005 (estimated 120 deaths in 2005) and Hurricane Ike, when it made landfall in Galveston (over 100 deaths in 2008).

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