Just over a week after deadly flash floods swept through Texas Hill Country, the region may once again face a life-threatening deluge as slow-moving thunderstorms bring heavy rain, flash flooding, and rapid river rises to parts of central Texas Sunday.

The homeland security secretary said a report that thousands of calls to a disaster hotline went unanswered because of staffing cuts was “false.”

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.
