The National Weather Service extended its flood watch for several counties in Central Texas and the Hill Country until 1 p.m. Sunday.

At least 32 people have died and dozens of children are missing in the Texas Hill Country after catastrophic flooding, with officials warning the casualty count will climb as forecasts call for more rain and the risk of further flash floods in the coming days.

The death toll was previously reported to be 27 earlier in the day. More than 850 people have evacuated from Kerr County in south-central Texas amid floods that caused the Guadalupe River near Kerryville to surge by more than 20 to 26 feet,
