The Great Appalachian Storm of November 1950 was a large extratropical cyclone which moved through the Eastern United States, causing significant winds, heavy rains east of the Appalachians, and blizzard-conditions along the western slopes of the mountain chain. Hurricane-force winds, peaking at 110 miles per hour (180 km/h) in Concord, New Hampshire and 160 miles per hour (260 km/h) in the New England highlands, disrupted power to 1,000,000 customers during the event. In all, the storm impacted 22 states, killing 353, injuring over 160, and creating US$66.7 million in damage (1950 dollars). At the time, U.S. insurance companies paid more money out to their policy holders for damage resulting from this cyclone than for any other previous storm or hurricane. The cyclone is also the highest-ranking winter storm on the Regional Snowfall Index with a maximum value of 32.31; and one of only sixteen storms to rank as a Category 5 on the scale.
