Fairfax County and much of the region could see up to nine inches through tomorrow. The National Weather Service issued a winter storm warning for the region last night. Snow accumulations between four and nine inches are expected. The Virginia Department of Transportation is urging residents to avoid unnecessary travel during today’s storm. So far, crews are treating roads and will begin to plow snow once it accumulates throughout the day. “With more than 3,000 pieces of equipment, crews will work around the clock on state-maintained roads, focusing on clearing roads that carry the most traffic first. These include interstates, primary roads, and routes connecting public safety and emergency services. Crews can then focus on neighborhoods and lower-volume roads,’ VDOT wrote in a statement earlier this morning.”
