HOUSTON -

The latest, and arguably strongest, winter storm to strike the east coast this season is delivering a wallop from Georgia to Virginia Tuesday, with ice and snow crippling cities from Atlanta to Charlotte to Raleigh.

The storm will continue up the east coast as a Nor'easter on Thursday, delivering up to 15 inches of snow from Washington, D. C. through New England.

By Wednesday afternoon, up to 1/2 inch of ice had accumulated near Atlanta, with thicker accumulation -- between 1/2 and 1 inch -- in east-central Georgia stretching into South Carolina.  In addition to ice, some parts of South Carolina reported up to 6 inches of snow.  Similar snow totals were reported in North Carolina through mid-afternoon Wednesday.  Traffic in many cities is at a standstill and power outages from ice on trees and power lines are widespread.

The storm will move up the east coast overnight Wednesday night and Thursday.  Washington, D.C. and Baltimore are forecasting 8 to 12 inches of snow through Thursday afternoon.  From Philadelphia to New York City 6 to 10 inches of snow are expected.  Away from the coast and in higher elevations along the spine of the Appalachian Mountains up to 15 inches of snow is likely.
