The search for survivors from the deadly Texas flash floods has continued into its fourth day, as authorities warned of further adverse weather in the area and the death toll topped 80 people.

Catastrophic flooding struck central Texas on Friday as the Guadalupe River surged by more than 20 to 26 feet within 90 minutes, causing widespread devastation and forcing mass evacuations in Texas Hill Country. At least 80 people have been killed in the floods while others remain missing or displaced and more than 850 people required rescuing.
