KERRVILLE, Texas (AP) — Emergency crews suspended their search for victims of catastrophic flooding in central Texas on Sunday morning amid new warnings that additional rain would again cause waterways to surge. It was the first time a new round of severe weather has paused the search since the flooding earlier this month.

A National Weather Service advisory warned of another 2-4 inches of rain falling in the region − and isolated areas could see 9-12 inches.

Heavy rains caused multiple rivers in Central and North Texas to swell by more than 20 feet. Search efforts for victims of the July Fourth floods were suspended until Monday.

The National Weather Service warned that the Guadalupe River could surge to nearly 15 feet—5 feet above flood stage—by Sunday afternoon.
