A MAMMOTH winter storm has killed nine people and brought Washington D.C. and New York to a standstill over the past 36 hours.
NASA astronaut Scott Kelly tweeted an image of the blizzard, engulfing much of the United States and in particular, the Eastern Seaboard, from the International Space Station.
A state of emergency was declared in Washington D.C. and New York City, as well as in Tennessee, North Carolina, Virginia, Maryland, Pennsylvania, New Jersey and parts of other states.
Up to 2ft of snow has fallen in cities across the east coast, with as much again forecast to fall by today.
Meteorologist Ryan Maue, of WeatherBell Analytics, said 80 million people were affected, and a quarter of the US is now blanketed by snow.
He said: “This is going to be one of those generational events, where your parents talk about how bad it was.”
There were thousands of road crashes in the treacherous conditions. Some 7,600 flights were cancelled – about 15 per cent of those scheduled – according to the flight-tracking service FlightAware.
Dozens of flights to and from the UK were among those grounded.
Hurricane-force winds of 75mph were recorded at Dewey Beach in Delaware, and at Langley Air Force Base in Virginia.
Life-threatening blizzard conditions were expected to persist throughout the weekend.
