Ivan weakens slightly
Hurricane Ivan has weakened a bit, as it moves through the southern Gulf of Mexico. It's now a Category Four storm, with top winds of 155 miles an hour. Forecasters expect it to weaken a little more over the next 24 hours. Parts of Cuba are still under a hurricane warning. The storm surge and waves from Ivan are expected to diminish today. There's a hurricane watch in effect for the Gulf Coast from Morgan City, Louisiana to St. Marks, Florida -- including the New Orleans area. Five Florida counties are urging people to leave -- or, in some cases, ordering them to.
