Rating Scale for Northeast Snowstorms

This is probably old news to a lot of people, but it's new to me. In March 2004 a new intensity scale for measuring the intensity and impact on snowstorms came out. The rating ranges from 1 to 5, with 5 being extreme. The ratings are based on snow depth, area affected, and size of population affected, although I haven't read it in great detail yet. It would be interesting to see how the ratings would change if applied on a state level. The last part of the article provides a list of the most intense storms over the past several decades. By he way, the most intense storm was not the Blizzard of 1888.
