A car stranded in the water in Upper Marlboro by the Prince George's County courthouse.
Rising waters have prompted Fairfax County authorities in part of Huntington to evacuate. Officials along the Susquehanna river in Maryland have ordered mandatory evacuations of Port Deposit and voluntary evacuations of Perryville.
High water and storm damage have closed scores of roads, including parts of heavily-traveled U.S. Highway 301 in southern Maryland and parts of the beltway in southern Alexandria and Fairfax County.
According to Prince George's County Police, Upper Marlboro is completely shut down due to flooding. Tomorrow, the Prince George's County Administration building and court house will be closed due to flooding as well.
Five VRE trains have been stranded because of flooding.
Officials urge people to not attempt to cross floodwater in their cars and to seek alternate routes to flooded roads.
