Thousands of residents north and south of the Mississippi-Louisiana border were ordered to evacuate Thursday because of the possible failure of an Isaac-battered dam. Officials are considering breaching the Lake Tangipahoa dam in order to direct water into a forested area and prevent massive flooding to low-lying residential communities downstream. "If you live in these areas, leave immediately for higher ground," the National Weather Service warned Thursday.
