Blizzard conditions are expected to persist throughout the day across the East coast.

In addition to snow and hurricane-force winds, the National Weather Service predicted up to half an inch of ice for the Carolinas and potentially serious coastal flooding for the mid-Atlantic region. 

Here's some of what's happened so far:

• At least 10 deaths have been blamed on the weather, most of them in traffic accidents.

• Motorists have also reported being stranded for hours along pockets of the Pennsylvania Turnpike. 
• In Washington all mass transit is to be closed until Monday. 
• Mayor Muriel Bowser implored residents and visitors to "find a safe place and stay there''. 
• In New Jersey, 40,000 people were without power on Saturday morning, most of them along the coast. 
• Eighteen to 24in of snow are predicted for Washington, Baltimore and Philadelphia; 24 to 30in for areas just north and west of Interstate 95 outside those two cities; and 15 to 20in for New York.
• New York City has banned all non-emergency travel

New Jersey governor Chris Christie is giving a news conference - he just confirmed that 90,000 people are without power across the state, a figure that may rise.

As for flooding, he said the high tide on Saturday morning had led to "minor street flooding" across the coast, although some parts of southern New Jersey suffered significant flooding.

Saturday night's high tide, and the one on Sunday morning, will be less harmful, he said.

The US National Weather Service's Weather Prediction Center has tweeted this map, showing where the heaviest snows have fallen.

Parts of New Jersey have already seen heavy flooding this weekend - while the snow poses some problems, there is also a full moon, so a higher tide. Add to that strong winds, and there are real fears for low-lying areas.

Governor Chris Christie is about to speak at a press conference - we'll bring you news from that when we get it.

Warnings don't come much clearer than this one, from the office of New York mayor Bill de Blasio:

There are more warnings coming in from the city's mayor:

New York City has already seen a significant amount of snow, but mayor Bill de Blasio has just told a press conference more is to come.

Huge parts of the mid-Atlantic states are all white this Saturday. But there is more to come: north-east states such as New York, New Jersey and Connecticut could see much, much more of the white stuff over the coming hours.

Some parts of Washington DC have seen 13in (33cm) of snow overnight - and there is more to come.

Here's one DC resident who is more than happy with the cold conditions.
