Northeast starts to dry out after flash flooding claims at least 5 lives in Pennsylvania

An already saturated Northeast began drying out Monday after a second round of heavy rain in a week, including a flash flood in Pennsylvania that claimed at least five lives over the weekend.

A 9-month-old boy and his 2-year-old sister remained missing in Upper Makefield Township in Bucks County, Pennsylvania, which is along the Delaware River, after they were swept away late Saturday afternoon while traveling in a vehicle.

Fire Chief Tim Brewer said the area got about 6 1/2 to 7 inches of rain (about 18 centimeters) in 45 minutes.

The children are part of a Charleston, South Carolina, family visiting family and friends. They were on their way to a barbecue when their vehicle got stuck in the flash flood, Brewer said.

“As they tried to escape the fierce floodwaters, Dad took his 4-year-old son while the mother and the grandmother grabbed the two additional children,” he said. The father and son were “miraculously” able to get to safety. “However the grandmother, the mother, and the two children were swept away by the floodwaters,” Brewer said. The mother was among those later found dead.

A news conference was planned for Monday morning.

Flash flooding hit parts of New Hampshire, Massachusetts, Connecticut, New York, and New Jersey over the weekend. A confirmed tornado touched down Sunday morning in North Brookfield, Massachusetts, but no injuries or major property damage were reported. In New Hampshire, where some roads caved in several towns, heavy rain postponed Sunday's NASCAR race at the New Hampshire Motor Speedway by a day.

Vermont reported no immediate safety threats following historic flooding nearly a week ago that dumped up to two months' worth of rain in two days. U.S. Transportation Secretary Pete Buttigieg planned to visit the state later Monday.

More rain was in the forecast for Tuesday.

Sunday’s strong storms led to hundreds of flight cancellations at airports in the New York City area, and hundreds were delayed.

New York Gov. Kathy Hochul said 5 inches (13 centimeters) of rain fell within two hours in Suffolk County on Long Island. The state saw $50 million in damages from storms in the past week.

In North Carolina, floodwaters were blamed for the death of a 49-year-old woman whose car was swept off a road in Alexander County late Saturday night. A man who was in the car with her was rescued.
