New York, New Jersey and Connecticut are under winter storm warnings Sunday as the entire region deals with a significant snowstorm. Tri-State Area officials had been issuing warnings and discussing the states' preparations in the days leading up to the storm.

New Jersey Gov. Phil Murphy declared a state emergency for all 21 counties in the Garden State. A winter storm warning was in effect for 10 counties in the northern part of the state, where 6 to 8 inches (15 to 20 centimeters) of snow is expected to fall from Sunday afternoon through the late evening.

Most of the tri-state was scheduled to be under a winter storm warning by the afternoon, when conditions pick up and heavy snow bands could drop as much as an inch of snow per hour. For some, it’ll be the most snow in nearly three years.
