Here's how the Kerr County sheriff says families can report people still missing in the catastrophic flooding along the Guadalupe River.

At least 67 people are dead after heavy rain lashed Texas, leading to "catastrophic" flooding. Texas Gov. Greg Abbott said emergency responders remained in a search and rescue posture, hours after the flooding along the Guadalupe River inundated nearby areas.

Hundreds of rescuers have been deployed to search for people missing in central Texas, after flash floods killed 51 people, including 15 children. The worst affected area is Kerr County where 43 people have died and where 27 children remain missing from a Christian youth camp located along the River Guadalupe.
