The number of dead from the devastating floods across central Texas surpassed 100 as dozens of people remain missing. In Kerr County, at least 84 people died, including 28 children, according to officials.

A search for Texas flood survivors intensified as Texas Governor Greg Abbott issued a disaster declaration for nearly two dozen Texas counties.

Flash flood alley is a curved-shaped region about 300 miles long and 50 miles wide in central/south-central Texas, extending from north of Dallas to southwest of San Antonio. Its location, weather patterns, and geology often combine to create devastating floods.

Flash floods in Texas have killed more than 100 people, many of them children. Heavy rains fell quickly in the predawn hours Friday in the Texas Hill Country.
