Tropical Storm Sally is forecast to be a hurricane by the time it makes landfall in southeast Louisiana early Tuesday. And it'll bring some strong winds to the Mississippi coast and many of the state's other southern counties. But heavy rain and flooding are the biggest concerns. And the Mississippi National Guard is pre-positioning equipment at Camp Shelby in case it's needed for search and rescue missions in flooded areas. Gov. Reeves says some areas could get 15-20 inches of rain. The eye of the storm is forecast to push into south Mississippi near Columbia and turn to the northeast with up to eight inches of rain as far north as Meridian.
