There's already been 18 inches (45cm) of snow recorded in some eastern parts of Pennsylvania with the heaviest snow moving across Delaware, Pennsylvania, New Jersey, New York, Connecticut, Rhode Island and Massachusetts through Monday.
Some areas could see around 2ft (60cm) of snow before the storm moves away during Monday night.
There will be some huge drifts of snow as winds gust up to 70mph, strong enough to bring down trees and powerlines.
The storm will then affect maritime Canada Monday night and into Tuesday.Another round of snow will move across the northeast of the US on Wednesday as an 'Alberta clipper' area of low pressure races through.
