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

Often the number of people that are reported missing in a natural disaster turns out to be much greater than the actual final tally.

More than 160 people are still believed to be missing in Texas days after flash floods killed over 100 people during the July Fourth weekend, the state's governor said Tuesday.
