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.

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

Nearly a week after deadly floods struck Central Texas, search and rescue teams are continuing to probe debris for those still missing.
