Heavy rains pounded an already saturated Northeast on Sunday for the second time in a week, spurring another round of flash flooding, cancelled airline flights and power outages. In Pennsylvania, a sudden flash flood late Saturday afternoon claimed at least five lives.

At least five people died and two childen, a 9-month-old boy and his 2-year-old sister, remained missing, authorities said.
