The highest AQ index in Louisiana (as of 12:00 CDT) is currently the Baton Rouge Area area. Particle Pollution (PM2.5) is measuring at 66 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Particle Pollution (PM2.5) will be in the Baton Rouge Area area. It is forecasted to be Good, meaning air quality is satisfactory, and air pollution poses little or no risk.
Wednesday, as Tropical Storm Arthur approaches Louisiana from the southwest, gusty southerly winds will effectively disperse pollutants. Furthermore, thunderstorms and periods of heavy rain will enhance atmospheric mixing and inhibit ozone formation. Therefore, AQI levels will be Good to high-Good statewide. Thursday, the remnants of Tropical Storm Arthur will traverse the Bayou State, producing continued showers, thunderstorms, and periods of heavy rain. These weather conditions will reduce ozone production and keep pollutants well dispersed. As a result, AQI levels will be Good. Friday, as a slow-moving cold front stalls across northern Louisiana, light to moderate southerly winds will aid pollutant dispersion. Additionally, lingering clouds and scattered thunderstorms will limit ozone development, keeping AQI levels Good.
