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.

Gov. Greg Abbott says 161 people remain missing after catastrophic Central Texas flooding, as the death toll climbs to 109 and search efforts intensify.

At least 90 people are dead after heavy rain led to devastating flooding in Texas. Kerr County was hit the hardest, with at least 75 deaths, including 27 children. President Donald Trump signed a disaster declaration for the county and the Federal Emergency Management Agency is on the ground there.
