A notable flood threat is on tap for some of the driest areas of the United States as an ailing former Hurricane Priscilla combines with another storm system to create a long-lasting rainfall event.

Duck Dynasty” star Priscilla Robertson has announced that she’s given birth to her first child. The 19-year-old welcomed a baby girl with boyfriend Dillon Nash, who shared the news on Instagram. Nash celebrated their daughter’s arrival by uploading a black-and-white photo of the newborn holding his finger.

Hurricane Priscilla has intensified into a Category 2 storm off the west coast of Mexico and is forecast to bring heavy rains and gusty winds to Baja California Sur.

Three months after Duck Dynasty’s Jessica Robertson announced that her daughter Priscilla Robertson was pregnant with her first child, the 19-year-old gave birth to a baby girl.

Starting Thursday, the remnants of Hurricane Priscilla will bring storm chances ranging from 40%-70% in the Phoenix area. Phoenix National Weather Service meteorologist Matt Salerno says the area around Globe, which was hammered by a fatal flood last month, is expected to see 1 to 2 inches of rain fall.

Hurricane Priscilla was beginning to lose some punch but was still a powerful Category 2 storm off Mexico's Pacific coast, the Miami-based National Hurricane Center says.
