I have only heard two updates that I can verify as of 9 am eastern about casino closings in Biloxi.
Grand Biloxi and Isle of Capri have temporarily closed their Biloxi Casinos.
We will continue to update this post as the day goes on. If you have any updates about closings, please post a comment below.
According to the Biloxi Sun-Herald web site, the Beau Rivage is also closed due to Hurricane Gustav, as of Sunday, August 31.
