New York City is in lockdown as the American east coast braces itself for mega-storm Hurricane Sandy.
Mayor Michael Bloomberg has ordered the evacuation of low-lying areas of the city, which could affect 375,000 people, as well as the closure of all public transport saying the hurricane is a "serious and dangerous storm".
75mph winds are expected to bring a "life-threatening" surge of floodwater right across the Mid-Atlantic coast as well as 10in of rain and 2ft of snow.

Bloomberg said in a press conference: "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."
President Obama urged Americans "to take this very seriously and follow the instructions of your state and local officials, because they are going to be providing you with the best advice in terms of how to deal with this storm over the coming days" in a separate press conference.
A state of emergency has been declared in Maryland, New York, Pennsylvania, Virginia, Washington DC and a coastal region of North Carolina.

The subway will close from 7pm (23:00 GMT) on Sunday evening and all buses will cease two hours later. It is only the second time in history that New York's travel network has been shut down, the first being last year when Hurricane Irene struck.
Sandy has already killed 60 people in the Caribbean in the past week including a British man who was blown off the roof of his luxury Bahamas home whilst trying to repair a window shutter.

Governor Andrew Cuomo said: "A situation like this, you don't want to be overly panicked and overly prepared, but you want to be prudent, you want to do what's necessary."
Many major airlines have announced they will be suspending flights into New York and Washington DC on Monday.

The New York Stock Exchange has no plans to close as yet. Spokesman Rich Adamonis told Reuters news agency: "We continue to monitor the situation and to communicate with government officials, regulators, and markets participants."
New Jersey Governor, Chris Christie, warned people not to be complacent: "I know everyone's saying this isn't going to happen… that the weathermen always get it wrong.
"We have to be prepared for the worst here. I can be as cynical as any of you but when the storm comes, if it's as bad as they're predicting it will be, you're gonna wish you weren't as cynical as you might otherwise have been."
Barack Obama and Mitt Romney have had to amend campaigning plans to take account of the extreme weather. Obama is holding conference calls to plan an emergency response whilst Romney is heading to Ohio instead of a planned trip to Virginia.

HuffPost's Katie Bindley reports:
Like all the competitors who trained for the 2012 NYC Marathon, Hannah Vahaba will not be running the race this year. But she also will never forget her moment at the finish line. After traveling in from Atlanta, Vahaba picked up a marriage proposal in Central Park on Saturday without having to traverse the 26.2-mile course.
"This is my fiance," said Vahaba, 31, who had tears running down her face as she stood in Central Park where the race would have ended, just moments after Martin O'Donoghue had proposed.

On Long Island, Cuomo demands Accountability from Utilities
At a massive food distribution event at Republic Airport in Farmingdale, Cuomo said power has been restored to 60 percent of the New York metropolitan area.
LIPA reported Saturday evening that 460,000 customers remained without power, down from more than 900,000 initially.
"I've warned the utility companies repeatedly they operate under a state charter, essentially," Cuomo said. "The utility companies are not happy with my warning and frankly, I don't care."
"The customers are not happy. The bill payers are not happy and the people without power are not happy," Cuomo said. "People are suffering. It is an issue of safety and if the utilities were not prepared we will hold them accountable."
