A clipper system and coastal storm merged to create blizzard conditions in parts of the Northeast from the 8th through 9th. The storm dumped record-setting snowfall from New York to Maine. The highest snowfall total of 40 inches (101.6 cm) was reported in Hamden, CT. Strong winds (a gust of 83 mph (37 m/s) was reported in Falmouth, MA) brought whiteout conditions to much of New England and whipped up waves that carved a 1,600-foot-wide (487.68 m) hole in the barrier beach near Chatham, MA. In New York, the storm left more than a hundred cars stranded along the Long Island Expressway while in Connecticut there were reports of over a dozen collapsed roofs due to the snow. The storm left some 650,000 customers without power and resulted in a dozen deaths. At the end of the month, a potent storm brought a mix of precipitation to the Northeast. Up to 19 inches (48.26 cm) of snow was reported in southwestern Vermont while 1/2 inch (1.27 cm) of ice accumulated in northwestern New Jersey and nearly 2.00 inches (50.8 mm) of rain fell in eastern New York. The storm set precipitation records at eleven climate sites.
