Miller classification

A nor'easter is a macro-scale extratropical cyclone that travels along the East Coast of the United States and Atlantic Canada.

These storms track north-northeastward and typically attain peak intensity between New England and the Maritime Provinces of Canada.

[3] This is possibly due to the fact that the cyclones undergo bombogenesis as they travel along the coast, causing severe conditions from high winds and heavy precipitation.

[1] Storms that receive the type A classification develop primarily in the Gulf of Mexico or along the southern East Coast, near Georgia and South Carolina.

[2] When this re-development occurs, the storm produces precipitation, including heavy snow, along the inland parts of the Mid-Atlantic.

[1] A study written by Albright and Cobb (2004) showed that there are five predominant patterns that produce four inches or more of snowfall across the Mid-Atlantic.
