The highest AQ index in Louisiana (as of 8:00 CST) is currently the Baton Rouge Area area. Particle Pollution (PM2.5) is measuring at 57 (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.
Saturday, light southerly winds ahead of an approaching cold front will hinder pollutant dispersion. In addition, lingering thin-density smoke from agricultural fires will contribute to particle levels in some areas. Therefore, AQI levels will be high-Good to low-Moderate in most cities. Sunday, as a cold front departs to the south, moderate and gusty north-northeasterly winds will develop. These winds will increase dispersion and carry cleaner, cooler air into the Bayou State. As a result, AQI levels will be Good to high-Good. Monday, as surface high pressure moves southward into the Bayou State, northeasterly winds will weaken, becoming calm in the afternoon and evening. Additionally, morning and evening temperatures in the mid-20s to low-30s will produce a strong inversion, trapping pollutants in the lower levels of the atmosphere. These conditions will lead to high-Good to low-Moderate AQI levels statewide.
