More than 85million people in 20 states across the US live in the pathway of Storm Jonas, which hit the east cost with fury over the weekend.
At least 18 people are thought to have died, mostly from hypothermia and traffic accidents, and power is down for around 130,000 people in the freezing weather.
While conditions on Earth are pretty dangerous, astronaut Scott Kelly who is spending a year on the International Space Station has been capturing what the potentially record-breaking blizzard looks like from above:
As the low pressures system developed along the Gulf Coast Kelly could track its movement over the country.
As Jonas travelled up the east coast it collided with cold air further north, forming the dangerous winter weather system.
Scott's message for people down below? "Stay warm, stay safe!"
