At least four people killed and more than 20,000 people have been rescued after massive floods swept across US State of Louisiana, and officials warned Sunday that even though the rain had subsided, dangers loomed. 
"It's not over," Gov. John Bel Edwards said Sunday. "The water's going to rise in many areas. It's no time to let the guard down." Edwards said crews had already rescued more than 20,000 people. More than 10,000 people many in the Baton Rouge area were in shelters on Sunday night, Edwards said during a news conference, according to (NBC News). 
The flooding killed at least four people. The latest casualty was reported Sunday night, said Devin George, director of the state registrar. 
Edwards who also declared a state of emergency called the floods "unprecedented" and "historic." The heavy rain began Friday, with 6 to 10 inches falling on southeast parts of the state. Several more inches fell Saturday, according to the National Weather Service.
