"We're high up enough, so I'm not worried about flooding," said Mark Vial, who was pushing his 2-year-old daughter, Maziyar, in a stroller outside their building, where they live on the 15th floor. "There's plenty of food. We'll be OK."
The major American stock exchanges closed for the day, the first unplanned shutdown since the Sept. 11 attacks in 2001. The floor of the NYSE, typically bustling with traders on a Monday morning, fell within the city's mandatory evacuation zone. The United Nations canceled all meetings at its New York headquarters.
New York called off school on both Monday and Tuesday for the city's 1.1 million students, and the more than 5 million people who depend on its transit network every day were left without a way to get around.
"If you don't evacuate, you are not only endangering your life, you are also endangering the lives of the first responders who are going in to rescue you," Mayor Michael Bloomberg warned. "This is a serious and dangerous storm."
New Jersey Gov. Chris Christie was typically blunt: "Don't be stupid. Get out."
Craig Fugate, chief of the Federal Emergency Management Agency, said FEMA teams were deployed from North Carolina to Maine and as far inland as West Virginia, bringing generators and basic supplies that will be needed in the storm's aftermath.
"I have not been around long enough to see a hurricane forecast with a snow advisory in it," Fugate told NBC's "Today" show.
