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.
| Region | Index | Category | Area with snow (sq mi) | People under snow | Above the top threshold (sq mi) | People above it |
|---|---|---|---|---|---|---|
| Northern Rockies and Plains | 5.93 | Category 2, Significant | 468,103 | 4,839,423 | 163 | 1,333 |
| Upper Midwest | 0.90 | Below category 1 | 179,389 | 10,004,248 | 0 | 0 |
| South | 0.09 | Below category 1 | 91,419 | 3,075,408 | 0 | 0 |
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.
