Flash floods in Texas have killed nearly 90 people, many of them children. Heavy rains fell quickly in the predawn hours Friday in the Texas Hill Country, causing the Guadalupe River to rise 26 feet in just 45 minutes.

The death toll from the devastating floods across central Texas surpassed 90 as dozens of people remain missing. In Kerr County, at least 48 adults and 27 children died, according to officials.
