The 50th Anniversary of
The 1969 "100 Hour Storm"
February 22-28,1969

While the February 22-28, 1969 snowstorm is not as well known as the "78" Blizzard or the March 1993 "Storm of the Century", with snowfall depths of greater than 30 inches, it affected many more people than any other storm since 1900. NOAA's Regional Snowfall Index, which is based on how many people are effected, area of snowfall, and depth of snowfall, lists this storm as Number 1 in its rankings of great snowfalls and gives the 1969 Storm the respect it deserves
