The mean season

During the summer, waters in the Atlantic Ocean accumulate heat, which fuels a flurry of hurricanes at season's end. Most hurricanes reaching the Washington region do so after being downgraded to tropical storms. Notable exceptions were Isabel (2003), Floyd(1999) and Gloria (1985).
