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

This week in Texas, estimates put the number of people still missing from the Hill Country floods at 161, a daunting figure atop at least 120 deaths confirmed by authorities. But that missing person tally might not be as precise as it seems.

A Texas official said no person has been rescued alive from flood damage since Friday. This comes as the number of people missing remains above 150 and as questions remain about the emergency alerts preceding the catastrophic event.
