REMARKS:Sunday, mostly cloudy skies will inhibit ozone production and moderate southerly winds will help disperse pollutants throughout most of Louisiana. In the southeastern portion of the state, southerly winds will gradually transport a plume of Saharan dust into the region, increasing particle concentrations. As a result, AQI levels will be Good across most of the state, and low-Moderate in New Orleans and Baton Rouge. Labor Day and Tuesday, partly cloudy skies will continue to suppress ozone formation throughout Louisiana. However, light to moderate southerly winds will transport Saharan dust farther into the state, increasing particle concentrations and leading to Moderate AQI levels throughout Louisiana on both days.
