AlHijjah 13, 1433, Oct 29, 2012, SPA - Hurricane Sandy threatened some 50 million people on the heavily populated East Coast on Monday, and forecasters warned that New York could bear the brunt of the one-of-a-kind Superstorm. Federal Emergency Management Administrator Craig Fugate warned that the "time for preparing and talking is about over," as Sandy made its way up the Atlantic on a collision course with two other weather systems that could turn it into one of the most fearsome storms on record in the U.S. "People need to be acting now," he was quoted as saying by the Associated Press. Forecasters warned the mega storm could wreak havoc over 800 miles (1,300 kilometers) from the East Coast to the Great Lakes. States of emergency were declared from North Carolina to Connecticut. Airlines canceled more than 7,600 flights and Amtrak began suspending passenger train service across the Northeast. New York and Philadelphia moved to shut down their subways, buses and commuter trains Sunday night and announced that schools would be closed on Monday. Boston, Washington and Baltimore also called off school.
