Virginia
Virginia has some special considerations that affect tropical cyclone-related rainfall. Mountains to the west act as a perfect mechanism for upward motion during sustained east winds, which can lead to flash flooding and landslides in that region (e.g. Hurricane Camille). As a tropical system approaches from the south, a frontal zone sets up between the moist Atlantic Ocean and the drier landmass to the west. This boundary can set up two or three days in advance of a tropical storm, and can lead up to prolonged heavy rains across coastal sections (e.g. Hurricane Floyd). As the cyclone advances north, the boundary will slowly shift west, but progresses west of a Richmond/Washington, D.C. line.

Famous quotes containing the word virginia:
“While I am in favor of the Government promptly enforcing the laws for the present, defending the forts and collecting the revenue, I am not in favor of a war policy with a view to the conquest of any of the slave States; except such as are needed to give us a good boundary. If Maryland attempts to go off, suppress her in order to save the Potomac and the District of Columbia. Cut a piece off of western Virginia and keep Missouri and all the Territories.”
—Rutherford Birchard Hayes (1822–1893)
