ATLANTIC CITY, N.J. â€” A furious Hurricane Sandy made the westward lurch that forecasters feared and took dead aim at New Jersey and Delaware on Monday, washing away part of the Atlantic City boardwalk, putting the presidential campaign on hold and threatening to cripple Wall Street and the New York subway system with an epic surge of seawater.
Gaining speed and power through the day, the storm knocked out electricity to more than 1.5 million people and figured to upend life for tens of millions more. It clobbered the boarded-up big cities of the Northeast corridor, from Washington and Baltimore to Philadelphia, New York and Boston, with stinging rain and gusts of more than 85 mph.
As it drew near, Sandy moved closer to converging with two cold-weather systems to form a hellish superstorm of snow, rain and wind. Forecasters warned of 20-foot waves bashing into the Chicago lakefront and up to 3 feet of snow in West Virginia.
Airlines canceled more than 12,000 flights, disrupting the plans of travelers all over the world, and storm damage was projected at $10 billion to $20 billion, meaning it could prove to be one of the costliest natural disasters in U.S. history.
President Barack Obama and Republican challenger Mitt Romney canceled their campaign appearances at the very height of the race, with just over a week to go before Election Day. The president pledged the governmentâ€™s help and made a direct plea from the White House to those in the stormâ€™s path.
â€śWhen they tell you to evacuate, you need to evacuate,â€ť he said. â€śDonâ€™t delay, donâ€™t pause, donâ€™t question the instructions that are being given, because this is a powerful storm.â€ť
Sandy, which killed 69 people in the Caribbean before making its way up the Atlantic, began to hook left at midday and was about 40 miles south of Atlantic City by evening, moving west-northwest at almost 30 mph â€” faster than forecasters expected.
Pete Wilson, who owns an antiques shop in Cape May, N.J., at the stateâ€™s southern tip and directly in Sandyâ€™s path, said the water was 6 inches above the bottom edge of the door. He had already taken a truckload of antiques out but was certain he would take a big hit.
â€śMy jewelry cases are going to be toast,â€ť he said. â€śI am not too happy. I am just going to have to wait, and hopefully clean up.â€ť
New Jersey Gov. Chris Christie said people were stranded in Atlantic City, which sits on a barrier island and was mostly under water late Monday. He accused the mayor of allowing them to stay there.
With the hurricane fast approaching, Christie warned it was no longer safe for rescuers, and advised people who didnâ€™t evacuate the barrier islands to â€śhunker downâ€ť until morning.
â€śI hope, I pray, that there wonâ€™t be any loss of life because of it,â€ť he said.
By early evening, the hurricane was expected to barrel into southern New Jersey or Delaware. That would put New York City and Long Island along its dangerous northeastern wall, facing perhaps 11 feet of water.
While the hurricaneâ€™s 90 mph winds registered as only a Category 1 on a scale of five, it packed â€śastoundingly lowâ€ť barometric pressure, giving it terrific energy to push water inland, said Kerry Emanuel, a professor of meteorology at MIT.
â€śWe are looking at the highest storm surges ever recordedâ€ť in the Northeast, said Jeff Masters, meteorology director for Weather Underground, a private forecasting service. â€śThe energy of the storm surge is off the charts, basically.â€ť
In New York City, authorities worried that salt water would seep through the boarded-up street grates and through the sandbags placed at subway entrances, crippling the electrical connections needed to operate the subway.
Authorities also feared the surge of seawater could damage the underground electrical and communications lines in lower Manhattan that are vital to the nationâ€™s financial center.
Hours before landfall, there was evidence of the stormâ€™s power.
A construction crane atop a luxury high-rise in New York City collapsed in the wind and dangled precariously over the streets. Forecasters said the wind atop the building may have been close to 95 mph.
Off North Carolina, a replica of the 18th-century sailing ship HMS Bounty that was built for the 1962 Marlon Brando movie â€śMutiny on the Bountyâ€ť went down in the storm, and 14 crew members were rescued by helicopter from rubber lifeboats bobbing in 18-foot seas. Two other crew members were missing. They were believed to be wearing survival suits capable of protecting them from cold water for 15 hours.
At Cape May, water sloshed over the seawall, and it punched through dunes in other seaside communities. Sandy also tore away an old section of Atlantic Cityâ€™s historic boardwalk.
â€śWhen I think about how much water is already in the streets, and how much more is going to come with high tide tonight, this is going to be devastating,â€ť said Bob McDevitt, president of the main Atlantic City casino workers union. â€śI think this is going to be a really bad situation tonight.â€ť
In Maryland, at least 100 feet of a fishing pier at the beach resort of Ocean City was destroyed, and Gov. Martin Oâ€™Malley said there would be devastating flooding from the swollen Chesapeake Bay.
â€śThere will be people who die and are killed in this storm,â€ť he said.
At least half a million people had been ordered to evacuate, including 375,000 from low-lying parts of New York City, and by the afternoon authorities were warning that it could be too late for people who had not left already.
Millions of people stayed home from work. Sheila Gladden evacuated her home in Philadelphiaâ€™s flood-prone Eastwick neighborhood, which took on 5Â˝ feet of water during Hurricane Floyd in 1999, and headed for a hotel.
â€śIâ€™m not going through this again,â€ť she said.
Those who stayed behind had few ways to get out. New Yorkâ€™s subways, which serve 5 million people a day, were shut down. The Holland Tunnel connecting New York to New Jersey was closed, as was a tunnel between Brooklyn and Manhattan.
Stock and bond markets were closed Monday and Tuesday, the first shutdown since the days after the Sept. 11 attacks in 2001 and the first two-day closing of the stock market because of weather since a blizzard in 1888. The New York Stock Exchange is inside the mandatory evacuation zone in lower Manhattan, blocks from New York Harbor.
If the storm reaches the higher estimate of $20 billion in damage, that would put it ahead of Hurricane Irene, which raked the Northeast in August 2011 and caused $16 billion in damage. Hurricane Katrina, which killed 1,200 people, cost $108 billion.
