A blizzard is expected to dump significant amounts of snow, with reports of 1-2 feet already fallen in some areas, and potentially up to 48 inches in others. The storm has prompted a state of emergency in New York and travel bans in some areas, with other regions also experiencing heavy snowfall. The extent of the snowfall varies, with some areas receiving over a foot of snow, while others may see even more, and the storm's impact is being felt across multiple states.
