The destruction caused by Superstorm Sandy mounted Tuesday morning as electrical fires and record power outages added to the misery of devastating flooding in the Northeast.
By early Tuesday, more than 7 million customers shivered without electricity in 10 states and the District of Columbia in Sandy's chilly wake.
Sandy also claimed at least 16 lives across the United States, bringing the total number of deaths to at least 84 after the storm wreaked havoc in the Caribbean.
The storm sent trees crashing down and left neighborhood streets looking like rivers. Floodwaters rushed into New York's subway tunnels and ripped up part of Atlantic City's fabled boardwalk.
Hundreds of people were stranded in one New Jersey town alone Tuesday morning. And Connecticut's governor offered ominous advice in a Twitter post: "If u find urself surrounded by water, call 4 help if u can, then get 2 highest level of home. Hang a white sheet out a street-side window."
Authorities scrambled in boats to rescue trapped residents in several towns after a berm broke in Moonachie, New Jersey.
"Within 30 minutes, those towns were under 4 or 5 feet of water," said Jeanne Baratta of Bergen County police.
Hundreds of people had been rescued Tuesday morning, Gov. Chris Christie said.
"We'll have to rescue hundreds more," he said.
Meanwhile, the stench of smoke was blown across flooded streets as fierce winds and rising waters shorted out power lines and sparked fires in places such as Lindenhurst, New York.
At least 50 homes burned to the ground in the Breezy Point neighborhood of Queens, fire officials said. The cause of the blaze was not immediately released. More than 200 firefighters battled the leaping flames.
Elsewhere in New York City, emergency backup power failed and 10 feet of water flooded the basement of NYU Langone Medical Center, prompting the evacuation of 260 patients. Nurses manually pumped air to the lungs of those on respirators.
Atlantic City, New Jersey, became an extension of the Atlantic Ocean. Seaweed and ocean debris swirled in the knee-deep water covering downtown streets.
Like many New Jersey residents, Montgomery Dahm stared in awe at the feet of water that deluged Atlantic City.
"I've been down here for about 16 years, and it's shocking what I'm looking at now. It's unbelievable," he said. "I mean, there's cars that are just completely underwater in some of the places I would never believe that there would be water."
Along the East Coast, residents reported images they'd never seen before.
"We just looked out the window, and there's this river flowing through the middle of Manhattan," said Earl Bateman, a stockbroker who has lived in New York for 30 years.
More fury to come
But the weather nightmare isn't over yet.
Forecasters say the entire Northeast corridor of the United States will bear the brunt of Sandy.
Fierce winds will blow from northern Georgia into Canada and as far west as Lake Michigan on Tuesday. Meanwhile, heavy rains will soak New England and parts of the Midwest.
And a blizzard spawned by Sandy will bring 2 to 3 feet of snow to the mountains of West Virginia by Wednesday morning.
"It's 3 feet of heavy snow. It's like concrete," said meteorologist Reed Timmer, who is riding out the storm in Elkins, West Virginia.
Thousands of flights will remain grounded Tuesday. Federal government offices will stay closed. And it will take between 14 hours and four days to get the water out of the subway tunnels in New York.
"The New York City subway system is 108 years old, but it has never faced a disaster as devastating as what we experienced last night," said Joseph Lhota, chairman of New York's Metropolitan Transportation Authority. "Hurricane Sandy wreaked havoc on our entire transportation system, in every borough and county of the region."
The full scale of Sandy's wrath has yet to be determined. But according to a government prediction, the storm's wind damage alone could result in more than $7 billion in economic loss.
Power outages spanned from Virginia to Maine, and the iconic Manhattan skyline turned eerily dark.
"This will be the largest storm-related outage in our history," said John Miksad, senior vice president of power company Con Edison.
After killing at least 67 people in the Caribbean, Sandy made landfall Monday night in southern New Jersey, sending waves of water into major cities along the East Coast.
Officials blame Sandy for at least 16 deaths in the United States. Several victims, including an 8-year-old boy in Pennsylvania, died after being hit by a tree or tree limb. Another death was reported in Canada, where flying debris struck a woman.
As the devastation spread, President Barack Obama signed major disaster declarations for New Jersey and New York on Tuesday.
