The blizzard disrupted several regions, and in some areas the snowfall rate prevented snow plows from maintaining the roads. The blizzard caused flights and trains to be canceled, and left areas without power. Kentucky, Maryland, Virginia, West Virginia, and New Castle and Kent counties in Delaware declared a state of emergency. Seven deaths were reported to have been caused by the storm.
