At least 10 states from Louisiana to Delaware are under snow and ice alerts as this latest winter storm moves east.

Several states along the Atlantic Coast were set to receive up to a foot of snow as much of the central U.S. faced dangerously cold temperatures.

The last in a long train of storms will bring snow and ice to the Mid-Atlantic and Carolinas on Wednesday. While Washington will be near the northern edge of the storm starting late in the morning — with a dusting to a half-inch of snow possible in the District and areas to the south by the evening — impacts will be moderate to major farther south.
