A winter storm blanketed parts of the Northeast U.S. with over a foot of snow in several areas over the weekend. It's just a preview of what's forecast to be an even stronger and wider storm in the coming days, with the potential to bring snowfall not seen in years to several cities in the region.

The National Weather Service said a "rapidly strengthening storm" will develop in the central U.S. on Monday. Up to a foot of snow may fall on parts of the Midwest through Tuesday. Meanwhile, the U.S. Atlantic coast, especially North and South Carolina, are at risk of severe coastal flooding.
