More than half a million customers remain without power in Louisiana, while communities in Louisiana and Mississippi are still reeling from Isaac's deluge with multiple areas recovering from dam breaks or controlled releases of dams to prevent a disaster.
According to Entergy, 526,326 people were still in the dark in Louisiana as of 6:30 a.m. EDT Friday.
Meanwhile, with fears of the breaching of the Percy Quin Dam south of McComb, Miss., due to being stressed by Isaac's heavy rainfall, evacuations were forced for Tangipahoa Parish in Louisiana on Thursday.
The Associated Press reports that a controlled breach of the Percy Quin Dam began late Thursday afternoon to prevent a failure of the dam that could send flood waters rushing south into communities such as Kentwood, La.
Dams have also failed in Slidell, La., and a controlled breach was performed in Plaquemines Parish, La.
