A major nor'easter is currently impacting the New York City metropolitan area, including Long Island and portions of New Jersey, prompting a blizzard warning. The storm is anticipated to bring heavy snowfall, potentially accumulating between 12 and 24 inches in some locations, along with strong, sustained winds exceeding 35 mph. The combination of heavy snow and high winds is creating dangerous whiteout conditions, significantly reducing visibility and making travel extremely hazardous.
