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.

The search for more than 160 people still unaccounted for in flood-ravaged central Texas has been temporarily halted due to ongoing rainfall in the region. Officials say the majority of the nearly 130 confirmed deaths occurred over the Fourth of July weekend in Kerr County, one of the areas hardest hit by the historic flooding.
