The National Hurricane Center is monitoring a broad area of low pressure that is causing showers and storms across the central Gulf of Mexico. The NHC has increased the likelihood a tropical system forms to a 70% chance. A tropical depression is possible today or tonight as this disturbance interacts with a frontal boundary. This surge of tropical moisture is one of the ingredients that will bring a heavy rain threat to Acadiana today and tonight. Winds will pick up across the area, especially offshore tonight and Saturday. The next name on the list is Olga.
