A powerful storm pounded the eastern United States with wind and pouring rain, grounding hundreds of airline flights and threatening to create some of the worst coastal flooding in 14 years. It has been blamed for eight deaths across the U.S.
Airlines canceled more than 400 flights at the New York area's three major airports, said Steve Coleman, a spokesman for the Port Authority of New York and New Jersey.
One person was killed in South Carolina as dozens of mobile homes were destroyed or damaged by wind, and two died in car accidents - one in New York and one in Connecticut. The storm system already had been blamed for five deaths on Friday in Kansas and Texas.

Some New Jersey residents along the shoreline evacuated, and officials in Connecticut urged some coastal residents to do the same. Inland areas from upstate New York to Maine faced a threat of heavy snow.
