It hasn’t happened yet, but WMATA is warning residents to be mindful that Metrorail and Metrobus service will be significantly impacted by this weekend’s storm. We’ll be monitoring the transit situation closely as the storm progresses, and will update frequently as changes are announced.

For the Metrobus system, look for changes to progress similarly to the Dec. 19 storm. Service will likely be limited to snow emergency routes only at some point this evening, and may stop all together should road conditions rapidly deteriorate. Hopefully those calls will be made before stuff like this starts to happen.

As for Metrorail, the transit system has policies in place that require a shift to underground service only once the first eight inches of snow accumulates. Once that happens (and we’ll be sure to let you know when it does), refer to the Metro map below, which indicates Yellow Line service from Pentagon to Crystal City only, Red Line from Medical Center to Union Station, Orange Line from Ballston to Stadium-Armory, Green Line from Fort Totten to Congress Heights, and Blue Line from Ballston to Stadium-Armory.
