The storm by region

Each region’s thresholds are its own, so the same depth of snow counts for more in the South than in the Northeast.

The Regional Snowfall Index is NOAA’s ranking of snowstorms east of the Rockies by how much snow fell, over how wide an area and on how many people, region by region: the area and the population above four snowfall thresholds set for each region, weighted against that region’s own history. A storm is scored in each region it reached, on a scale from 1, notable, to 5, extreme.

Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
