The highest AQ index in Louisiana (as of 15:00 CDT) is currently the Lake Charles area. Ozone (OZONE) is measuring at 101 (Unhealthy for Sensitive Groups). This means members of sensitive groups may experience health effects. The general public is less likely to be affected.
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.
Monday, calm to light northeasterly winds will limit pollutant dispersion in Louisiana. Furthermore, mostly sunny skies, temperatures around 90-95F, and lingering thin smoke will promote ozone formation. Thus, AQI levels will be low- to mid-Moderate in most cities, with high-Moderate AQI levels expected in Baton Rouge. Tuesday, upper-level high pressure will reduce vertical mixing in the atmosphere. In addition, mostly sunny skies and temperatures around 90-95F will enhance ozone development, while light east-southeasterly winds will limit dispersion. Therefore, AQI levels will be low- to mid-Moderate over most of the state, with high-Moderate AQI levels expected to continue in Baton Rouge. Wednesday, southeasterly winds will strengthen slightly as a low pressure system develops over the central Plains, increasing pollutant dispersion in the Bayou State. Additionally, isolated afternoon thunderstorms will limit ozone formation. However, mostly sunny and warm conditions will lead to high-Good to low-Moderate AQI levels for ozone.
