The snow-weary D.C. region hunkered down for yet another major winter storm as a strong coastal system is expected to batter the area with a foot or more of fresh powder.

The National Weather Service forecast called for 10 to 20 inches of new snow by Wednesday evening, with a north wind gusting to near 40 mph causing blowing and drifting. Travel will be very hazardous, if not impossible, especially along secondary roads still buried after the weekend’s 2-foot or more dumping.
