Hurricane Irene zeroed in on Friday for a catastrophic run up the Eastern Seaboard. More than 2 million people were told to move to safer places, and New York City ordered the nation’s biggest subway system shut down for the first time because of a natural disaster.
Hurricane warnings were issued from North Carolina to New York, and watches were posted farther north, on the islands of Nantucket and Martha’s Vineyard off Massachusetts. Evacuation orders covered at least 2.3 million people, including 1 million in New Jersey, 315,000 in Maryland, 300,000 in North Carolina, 200,000 in Virginia and 100,000 in Delaware.
“This is probably the largest number of people that have been threatened by a single hurricane in the United States,” said Jay Baker, a geography professor at Florida State University.
