Three days before Katrina's second and third landfalls, the National Hurricane Center began predicting that the storm would make landfall as a major hurricane. By the next morning, on August 27, the NHC gave out a hurricane watch that included the New Orleans metro area, which was upgraded to a hurricane warning by 10:00 p.m. CDT that same evening. At this point, Katrina was a Category 3 hurricane with 115 mph (185 km/h) winds and about 335 miles (540 km) to the south-southeast of the Mississippi River's mouth.
