What is Nor'easter?

Nor'easter is a meteorological event commonly observed in the Northeastern United States and typically occurs during the winter months. It is characterized by heavy snowfall, strong winds, and the formation of high waves at sea. This event occurs when two significant air masses collide: cold air from the north meets warm air from the south. This collision usually takes place along the Atlantic Ocean coast.
