MIAMI, Florida (CNN) -- Hurricane Gustav churned into the Gulf of Mexico on Saturday night, still an "extremely dangerous" Category 4 storm threatening to blast the same region devastated by Hurricane Katrina three years ago. Saturday morning, Gustav was about 255 miles east-southeast of the western tip of Cuba. Gustav, a Category 4 storm with 135 mph (220 km/hr) top winds, was centered 485 miles (780 kilometers) southeast of the mouth of the Mississippi River, according to the National Hurricane Center's 6 a.m. GMT (2 a.m. ET) advisory. That's only 15 mph slower than when the storm first crossed land in Cuba. The U.S. National Hurricane Center said the storm could pick up even more strength as it enters the gulf's warmer waters.NEW: Gustav heads into Gulf after Category 4 hurricane slams into CubaAbout 10,000 Cubans flee to mainland, some in vintage cars, horse-drawn carriagesStorm expected to hit Gulf Coast on Monday or TuesdayCoastal Mississippi and New Orleans residents getting out
