New York City is preparing for a significant weather event as a powerful nor'easter is predicted to bring heavy snow and strong winds from Sunday into Monday. The tri-state area anticipates substantial snowfall, with projections indicating up to 18 inches in certain locations. According to the National Weather Service, nor'easters are storms that develop along the East Coast of the United States, typically characterized by strong winds, snow, rain, and the potential for flooding. These storms derive their name from the direction of the strongest winds, which generally blow from the northeast across New England and the Mid-Atlantic states.
