Washington Metropolitan Area Transit Authority will not run any buses or trains on Saturday or Sunday because of the forecast of a blizzard in the DC area.  Buses will run Friday until 5 p.m., while trains will run until 11 p.m.  Metro says it fears the wind will cause power outages, potentially trapping a lot of its passengers. WMATA General Manager Paul Wiedefeld said 'the actions we are taking today are all in the interest of our customers' and employees' safety, and will help us return to service once the storm passes and the snow is cleared."

The transit agency has often continued to run its trains underground during major snowstorms in the past, but that won't happen this time.
