Storm Grayson has shoved the US East Coast into a state of emergency as the "bomb cyclone" advances over coastal cities bringing in temperatures colder than Mars.
Shocking new graphics from NASA show the powerful winter storm advancing on the Eastern US with a trough of low pressure and arctic air.
NASA latest update on Storm Grayson said: "The storm is in the process of 'bombing out,' meaning its central pressure is going to drop at least 24 millibars in 24 hours.
US snow: NASA warned Storm Grayson may cause temperatures to fall nearly 24 degrees
"Much like a hurricane, this will allow the counterclockwise winds spinning around the surface low to intensify as well as help pull more cold air in behind the storm as it passes."
Storm Grayson has led to a state of emergency being declared in many parts of the United States' East Coast and residents have been told to take care in the states of Florida, Georgia, Virginia and North Carolina.
New York Governor Andrew Cuomo was also forced to declare a state of emergency after Storm Grayson began pummeling the Eastern US state with heavy snow.
Bill de Blasio, New York City’s mayor, has warned about the Arctic temperatures that could freeze the Big Apple and warned residents not to underestimate the storm.
Around 1,500 snow ploughs have been deployed in a desperate bid to keep residents safe.

He said: “Everyone has to take this seriously, whether you’re driving, whether you’re walking, these are going to be tough conditions to move around in.
“People should right away start thinking about changing your routine if you can. If you don’t need to be on the road you shouldn’t tomorrow morning. If you can use mass transit as an alternative that’s better.”
The National Weather Service (NWS) warned of "whiteout conditions" in the coastal states of Delaware and New Jersey, advising to avoid "unnecessary travel".
The NWS latest update said: "A very robust winter storm continues to track northward just offshore the East Coast bringing strong winds, heavy snow and coastal flooding from the Mid-Atlantic to the northeast.
"Widespread disruption to travel, especially for the northeast, may persist into the weekend. Winter Storm Warnings and Blizzard Warnings span from the Virginia Outer Banks to Maine."
