Remembering New England's "100-Hour Snowstorm" of 1969 - SnowBrains

"Records that are likely to never be broken again were set on Mount Washington, such as a 98 inch storm total, and 49 inches of snow in a singular day on February 25. This same season, the Mount Washington Observatory measured a total of 566 inches of snow, a record that still stands to this day."

"Typical Nor'easters develop from intense low-pressure systems that travel up the East Coast. As it reaches the northern states, the moisture-packed and typically warmer air will clash with the arctic air pushing down from Canada. This sharp temperature gradient leads to intense storms along the eastern states, capable of producing large amounts of snow in the winter."

"With this storm in particular, the center of the low-pressure system stalled just off the coast in the Gulf of Maine for nearly four days, which halted any progress of the snow exiting the region."

Fifty-seven years ago, a catastrophic 100-hour snowstorm impacted the entire Northeast, with particularly severe effects across Vermont, New Hampshire, and Maine. Mount Washington recorded extraordinary totals of 98 inches during the storm and 49 inches in a single day on February 25, establishing records unlikely to be broken. The seasonal total of 566 inches at Mount Washington remains unmatched. Significant accumulations occurred across the region regardless of elevation, with Pinkham Notch receiving 77 inches and reaching a snow depth of 164 inches. Lower elevations also experienced substantial snowfall, including Boston with over 26 inches and Portland, Maine with 27 inches. The storm resulted from a low-pressure system stalling off the Gulf of Maine coast for nearly four days, preventing snow from exiting the region.
