Emergency crews have suspended their search for victims of catastrophic flooding in central Texas amid new warnings that additional rain will again cause waterways to surge

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

Multiple urban search and rescue teams from across the country that responded to the deadly floods in central Texas told CNN they were not deployed by the Federal Emergency Management Agency until at least Monday evening — days after any victim had been found alive.
