UPPER MAKEFIELD TWP., Pa. - Police say five people are dead after flash flooding in lower Bucks County Saturday evening.

Two other people, a 9-month-old child and 2-year-old child, remained missing as of late Sunday afternoon, authorities said. 

Officials said the family with the two little kids is from North Carolina and visiting family members. The family was on their way to a barbecue when the storm happened and the car was swept away. The dad grabbed a four-year-old from the car. The mom and grandmother grabbed the 2-year-old and 9-month-old. The dad and four-year-old survived. The mom was found dead. The two young children are still missing.

Bucks County Coroner Meredith Buck said Saturday night that two females and a male died in Upper Makefield Township. She said all the deaths are related to flash flooding.
