As it happened: US takes stock after SandyWednesday October 31, 2012 - 20:37 EDT
US president Barack Obama warned the threat from ex-hurricane Sandy was "not yet over" as Americans confronted the devastation caused by one of the biggest storms in the country's history.
Large areas of New Jersey were devastated by flooding and parts of New York City were at a virtual standstill after the storm hit, bringing with it a record 4-metre-plus tidal surge.
At least 45 people were confirmed to have been killed by the storm, which had earlier killed more than 60 in the Caribbean.
Millions of people are facing the possibility of days without power in plummeting temperatures.
In Queens, an entire district of around 80 homes was destroyed in an inferno which was sparked by an electrical fault as the storm hit, while New Jersey's governor described the devastation caused by flooding in Atlantic City as "unthinkable".
The storm was tracking north-west on Tuesday (US time) and was heading towards Canada, bringing heavy rain and snow to areas in its path.
With just a week to go until election day, Mr Obama was due to visit storm-hit areas of New Jersey on Wednesday while rival Mitt Romney, who had earlier converted one of his Ohio rallies into a storm relief fundraiser, was resuming campaiging in Ohio.
Look back on how events unfolded as the US woke up and surveyed the damage from the huge storm. (All times AEDT):
3:10pm: The official dubbed the "recovery tsar" for New Orleans after Hurricane Katrina is on his way to New York to help authorities deal with the impact of superstorm Sandy.
Professor Edward Blakely spoke to The World Today and warns there could still be more deaths on the US east coast because critical infrastructure like power, water and mass transportation has been so badly affected.
Professor Blakely told Tanya Nolan it could be up to a month before "hard" electricity infrastructure is back to full capacity.
"You have to restore power because New York City is high rise buildings. These high rise buildings house a lot of the population, and they cannot go up and down elevators. Many of these people are over 50, so movement of them is critical.
"The other thing is food - unless you have power, you don't have food. You have to keep the food cold and alive.
"So these are really emergency issues - as a matter of fact they're rescue issues - because if you don't have food and power, your chances of surviving are very low."
3:00pm: Foreign Minister Bob Carr says Australia has offered to help with the storm clean-up efforts.
He says there are 24,000 Australians living or travelling in areas affected by the storm, but so far there have been no reports of injuries or other mishaps.
"An exercise where we send people across who can both help and learn would be useful. Disaster management and recovery is something of an Australian speciality.
12:37pm: New York's JFK airport is expected to reopen on Wednesday (US time).
12:20pm: The aftermath of Sandy looks set to dominate the final week before the US presidential election.
Barack Obama is set to tour disaster areas in New Jersey on Wednesday while Mitt Romney is back campaigning in Florida.

11:25am: Atlantic City tavern owner Monty Duhn has told ABC News 24 about looking up and seeing the eye of the storm as it slammed into New Jersey:
"It was pretty much over us. I could actually see a little red sky and stars. I looked up and it was actually kind of nice. That lasted for a good 15-20 minutes, maybe half an hour, and then you slowly felt it coming and we got the tail of the hurricane and it really hit."
11:09am: This video shows New York mayor Michael Bloomberg surveying the damage in Breezy Point, Queens, where dozens of houses were destroyed by a fire which broke out as the storm hit:

9:26am: WEATHER UPDATE Post-tropical cyclone Sandy is now travelling north-west across Pennsylvania and is likely to move into Canada on Wednesday (US time).
The National Hurricane Centre says it is continuing to bring strong winds, heavy rain and snow to northern parts of the US.

8:50am: North America correspondent Lisa Millar is in New York City, where huge amounts of water are still swilling around the subway system.
"I've spent the last four five hours down in lower Manhattan where there is absolutely no mobile phone access.
"It's very difficult to get around. The subway is still shut down. I think what I've found most extraordinary is how high the water mark is down there, how much water there still is flooded into the tunnels in subways, which is why they're not even putting a timeline on when they're going to be able to reopen that critical public transport system for New York."
8:45am: Sandy: They said it:
8:30am: Former Age journalist Nick Miller is in New York and described the scene there this morning:

"Most people have been aware of what was about to happen to them. There've been very clear instructions of how to behave," he said.
"We're not getting too many reports of Australians placed in a situation where they haven't been able to effectively look after themselves.
"Quite frankly the consular burden on us has been very light."
But he says authorities are overwhelmed by the destruction.
"When the Atlantic Ocean decides to move onshore there's not a huge lot you can do about it except wait to clean up the consequences," he said.
7:00am: Lower Manhattan residents are being warned they may be without power for four days.
Electricity provider Consolidated Edison (Con Ed) says almost 250,000 homes are still without power in Manhattan.
"This is the largest storm-related outage in our history," a spokeswoman said.
"We try to restore lines that will get power to the most customers possible, but it will depend on the equipment."
The blackout area includes some NYC's wealthiest neighbourhoods, including Tribeca, Chelsea and Gramercy Park.
The ABC's Ben Knight is in the area and describes the scene:
"Everywhere you look here in Lower Manhattan there are trucks and men in hard hats beginning the cleanup of the city. And it's going to be a massive job," he said.
"There are hundreds of generators that are suddenly out running pumps starting to get the water out of shops and sewers, tunnels and underground car parks.
"On the streets, rubbish and debris are scattered all over the footpath. This is a bleak city the day after the flood and it's going to be some days before New York will even begin to return to normal."

"Every shop south of 42nd Street is shut and dark, except for those that have brought in generators to pump out the flood water.
"The scaffolding lying on the ground and the roads and footpaths are covered with a rainbow coloured film of oil that has been washed in from the harbour and the tunnels.
"Tourists are wondering around taking photos. The locals simply look stunned."
5:55am: US president Barack Obama has visited the headquarters of the Red Cross in Washington and warns the storm is "not yet over":

"He also noted his sadness over the loss of life associated with the storm so far.

11:10pm: Joe Lhota, the chairman of the New York Metropolitan Transport Authority (MTA), has told US media it is too early to tell how long it will be before the subway system is back up and running.
Mr Lhota says they will be assessing the situation over the rest of the day, but that it is likely that there will be no public transport until bus services resume on Wednesday at the earliest.
He says the MTA will be re-routing New York City's 4,000 buses to help commuters without the subway system, and has asked for patience from the 8 million people who use public transport every day:

9:55pm: Disaster modelling expert Richard Fenning predicts the economic cost of the storm could be as high as $20 billion.
But Mr Fenning says New York in particular will be well equipped to deal with the clean-up:
"You can't control the weather, certainly not in this instance, but what you can do to a certain extent is control your own reaction to that," he said.

9:30pm: A firefighter who attended the blaze in the Queens suburb of Breezy Point says they had to rescue dozens of people trapped inside burning homes:

Mr Dundas says New York has been plunged into darkness:
"We have a view from our apartment which is about 41 floors up, and all over Manhattan and Brooklyn and the entire island of Manhattan, but for a few of the real namesake skyscrapers, it is completely black.
"I can see from right down town in Battery Park and the World Trade Centre, all the lights are out there. And then looking right through to mid town, the lower east side, the East Village, Chinatown and various bridges, the Williamsburg Bridge, the Manhattan Bridge, the Brooklyn Bridge, they've all lost their power. All the lights are off."
7:50pm: Earlier Maryland governor Martin O'Malley said the storm has left its mark on the state, with hundreds of thousands left without power:
"We have power outages that are climbing to above 300,000 people without power and we expect that to go up to a million as the sound of trees cracking all over Maryland becomes the sound of this dark and stormy evening."
7:30pm: ABC correspondent Ben Knight is in Delaware, where he spoke to locals who had gathered in an evacuation centre in the town of Rehoboth Beach.
Ronald Roswell left his home in Rehoboth Beach at the height of the storm, when his apartment building flooded.
His mother drove his family to the shelter before returning to the apartment to ride out the storm:
"It was a treacherous out really. The rain was coming down sidewards, blowing the car sideways. You could hardly see out the windows but we made it here safely," Mr Roswell said.
"Really we didn't think it was going to be too bad but it started to get worse so my dad and mum were like 'do you all want to go to a shelter with your kids and your girlfriend?' So I was like 'yes'."
Mr Roswell said he felt safe because the area had not been hit by a storm of this magnitude in over 70 years, but he now fears for his mother's safety:
"Last time it hit was when my grandmother was young. It was about 1938 it hit here."
"I'm worrying about her, [my mother] right now. I want to see if I can use somebody's phone to call her again. I just pray to God you know everybody's safe out there and it clears over."
John Mulvey is the shelter's doctor, and said his experience as a responder to Hurricane Katrina meant he had an idea of how bad the storm could be:
"I think part of why Hurricane Katrina was so deadly was because there were about a dozen or so hurricanes that were going to hit New Orleans and didn't."
"So to a certain extent there was a bit of jadedness on the part of folks in New Orleans. I responded to Hurricane Katrina and I saw how confusing it can be to deal with that and I made a promise to myself that I wasn't going to let that happen in Delaware
