A winter weather system moving through the eastern U.S. could reorganize into a strong coastal storm off the East Coast later this weekend.

As millions of Americans hunker down for the winter storm, 19 states and Washington, D.C., have declared states of emergency.

One area to watch will be the South Coast, Cape, and southern Rhode Island, where an uptick in temperatures could spark some sleet and wet, heavier snow.

While the storm's worst impacts will be in southern states, the system will bring extreme cold and accumulating snow to New Hampshire.

There is “increasing confidence” Massachusetts will be hit by a coastal winter storm on Sunday, a weather event that the latest forecasts project will bring significant snowfall to the region.

A major snowstorm could hit Southern New England late this weekend after a stretch of "dangerous cold" descends over the region.

Increasingly unpredictable weather patterns are redefining our region’s identity, blurring the lines between our distinctive seasons.
