Another major winter storm is expected to slam portions of the central and eastern U.S. this week, with heavy snow and strong winds threatening to induce dangerous travel conditions, knock out power and ground flights, forecasters warned.

▪ If the storm’s center tracks near the North Carolina coast — say, 50 to 100 miles off shore — that would allow for more sustained northerly winds over the Piedmont and a more prolonged period of snow there. The Coastal plan might see snow in that case, but along the coast it would be mostly rain.
