Welcome to our continuing coverage of Sandy, a vast post-tropical storm set to make landfall at any moment in the north-eastern US. The storm, hundreds of miles across, is whipping a series of states with high winds, dumping heavy rain and threatening people and property in coastal areas with dangerous storm surges.
Although US weather authorities have reclassified Sandy as a post-tropical cyclone, winds are continuing at about 85mph (140km/h). A series of major cities from Washington DC to Philadelphia, New York and Boston are all experiencing severe weather.
Coastal areas of New Jersey are taking a battering, with much of Atlantic City facing flooding, and reports of water levels lapping at record highs in New York City. Power supplier Consolidated Edison has begun shutting off power to parts of lower Manhattan.
The centre of post-tropical cyclone Sandy has made landfall along the New Jersey coast, US weather authorities say, with wind speeds of 85mph (140km/h).
As of 20:00 EST (00:00 GMT) Sandy made landfall five miles (8km) south-west of Atlantic City, New Jersey, with sustained winds of 80mph (130 km/h).
As Sandy continues its path across the US north-east, now over land, Reuters news agency reports that more than two million people are now without power along the eastern coastline.

Reports coming out of New York are beginning to hint at the scale of the uncertainty and flooding that the city is now enduring. Residents in the city are facing power cuts and rising floodwaters in Manhattan and Brooklyn.
The US National Weather Service has reported a 73 mph (117 km/h) wind gust at New York City's JFK International Airport.
On the ground in the city, the radio chatter of the Brooklyn Fire and Hatzolah EMS dispatch service offers a look at the minute-to-minute challenges fire and rescue teams are facing in the borough.
