The East Coast was hit by a huge winter storm that could dump almost two feet of snow and bring 40 mph winds on the last weekend before Christmas. Washington, D.C., where a snow emergency was declared, could reach up to 22 inches of snow overnight, and Reagan National Airport was closed. Roads there were extremely dangerous and the National Weather Service warned simply, "do not travel." The National Guard had to be called in to rescue several hundred motorists in Virginia, and more than 500 people sought refuge in emergency shelters there. Most flights from Baltimore were canceled. Hundreds of flights were grounded in New York City. The storm is expected to reach all the way to Massachusetts by Sunday.
