Over 20 million people are currently on winter alert from Georgia to New England as strong but fast-moving storms hit the regions.
The heaviest snow is expected to fall over parts of the southern Appalachians and Mid-Atlantic states, including Washington, DC and Baltimore.
Washington expects 5 to 8 inches of accumulation, which will make this the heaviest snow in the district since January 2019.
Snowfall speeds of more than 2 to 3 inches per hour are possible, and visibility sometimes drops to less than a quarter mile this morning.
Along with dangerous winter weather, over 1.5 million people are under a tornado guard along coastal sections of the Carolinas, where an isolated tornado is possible through the morning hours.
Strong winds are also blowing power across the Southeast and Mid-Atlantic Seas with wind gusts from Florida to Virginia. Flood guards and coastal floods stretch from the Carolinas to New England.
