Southeastern Snowstorm of 2011
This very rare storm brought significant snow to parts of Alabama, Mississippi, Georgia and South Carolina before it turned up the coast and began impacting the Northeast. The storm really had two features associated with it, one in the south and one over the midwest. They eventually merged off the New England coast and developed into a powerful Nor'easter that brought heavy snow to New England. Cities in the south were ill prepared for the snow due to the rarity of the event. This caused the widespread closure of roads, schools, and buisnesses. The city of Atlanta only had eight plows working diligently to clear the cities streets but there was no way for them to keep up, making many city roads impassable for days. This powerful and rare storm was a Cat 2 in the Northeast, Southeast, and West North Central regions. It was a Cat 1 in the Ohio Valley, Upper Midwest, and Southern Regions.

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 |
|---|---|---|---|---|---|---|
| Southeast | 4.16 | Category 2, Significant | 178,169 | 31,894,275 | 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.

Every winter weather episode the Weather Service filed east of the Rockies in these dates. A few may belong to another system on the same days. Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
