More than a foot (30 cm) of snow was forecast for Boston and coastal areas in northern New England.
The storm is the product of a rapid plunge in barometric pressure that some weather forecasters are referring to as bombogenesis or a “bomb cyclone,” which brings fast heavy snowfall and high winds.
The cold has been blamed for at least nine deaths over the past few days, including two homeless people in Houston.
Passenger train operator Amtrak was running reduced service in the Northeast, while mass-transit systems in major metropolitan areas, including New York and Boston, remained open.
As a result, the accumulation of snow and winds intensifies, which can cause property damage and power outages.
