The December 1960 nor'easter was a significant winter storm that impacted the Mid-Atlantic and New England regions of the United States. The storm ranked as Category 3, or "major", on the Northeast Snowfall Impact Scale, and its snowfall extended from Virginia to Maine.[1] One of three severe storms during the 1960–1961 winter, the nor'easter dropped over 20 in (510 mm) of snowfall in parts of northern New Jersey and eastern Massachusetts. The initial low pressure system developed on December 10 in the Gulf of Mexico. It moved northward, then eastward, and a secondary low formed over South Carolina. It tracked northeastward and deepened to reach a minimum barometric pressure of 966 millibars by December 13. High winds and cold temperatures accompanied the storm, leading to blizzard conditions.[2]
