The highest AQ index in Louisiana (as of 16:00 CDT) is currently the Monroe area. Particle Pollution (PM2.5) is measuring at 55 (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 Ozone (OZONE) will be in the Baton Rouge Area area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Wednesday and Thursday, surface high pressure positioned to the northeast will generate light to moderate easterly winds across the Bayou State, aiding dispersion. However, these winds will also carry thin smoke and other regional pollutants into the region. Furthermore, partly to mostly sunny skies and temperatures in the 90s will enhance ozone formation. As a result, AQI levels will be high-Good to low-Moderate in most cities on both days. Friday, mostly sunny skies and very warm temperatures will continue to support ozone production in Louisiana. Additionally, lighter easterly winds will limit pollutant dispersion as surface high pressure extends over the state. As a result, AQI levels will be low- to mid-Moderate statewide.
