WASHINGTON CROSSING, Pa. (AP) — Heavy rains are pounding an already saturated Northeast for the second time in a week, spurring another round of flash flooding, canceled airline flights and power outages. A sudden flash flood also swamped a southeastern Pennsylvania road late Saturday afternoon, sweeping several cars away and claiming at least five lives. Authorities say three other people, including a 9-month-old child, remain missing in Bucks County’s Upper Makefield Township. Hundreds of flights were canceled at New York-area airports because of the weather, and Tweed-New Haven Airport in Connecticut closed its terminal. Thousands of homes and businesses lost power. In Vermont, which saw major flooding last week, officials said a dozen state roads remain closed.
