With three to four inches of heavy rain falling in a short amount of time, the National Weather Service said the area saw significant flash flooding.
The rain left drivers stranded on top of their cars and some metro commuters with water streaming into the station.
"Travel will be EXTRAORDINARILY dangerous," the National Weather Service warned on Twitter. "Stay out of low areas, if in a low area that may flood, seek higher ground. Stay off the roads if at all possible. This is not the 'usual' flooding."

The rain flooded the main power vault at D.C.'s National Archives, closing the building. The National Archives is home to the Declaration of Independence, the Constitution and the Bill of Rights; all those documents are safe, the National Archives and Records Administration said.
The downpour even appears to have affected the White House basement.
D.C. Mayor Muriel Bowser urged drivers to stay off the roads.
