The highest AQ index in Louisiana (as of 16:00 CDT) is currently the Baton Rouge Area area. Particle Pollution (PM2.5) is measuring at 54 (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 Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Sunday, periods of light southerly to southeasterly winds will limit dispersion. Furthermore, partly to mostly sunny skies and warm temperatures across much of the state will aid ozone production. Thus, AQI levels will be high-Good to low-Moderate in most cities. Monday, south-southeasterly winds will strengthen, enhancing pollutant dispersion. Additionally, increasing clouds and scattered showers across the southeastern portion of the state will reduce ozone formation. Therefore, AQI levels will be Good to high-Good. Tuesday, a morning inversion will confine pollutants near the ground, while patchy morning fog will enhance particle production. However, scattered showers and thunderstorms and periods of moderate southerly to southeasterly winds will aid dispersion in the afternoon. As a result, AQI levels will be high-Good to low-Moderate in most cities.
