The highest AQ index in Louisiana (as of 4:00 CST) is currently the Lake Charles area. Particle Pollution (PM2.5) is measuring at 52 (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.
Monday, as a cold front approaches from the northwest, moderate and gusty south-southeasterly winds will disperse pollutants and bring clean air into Louisiana. As a result, AQI levels will be Good statewide. Tuesday, as the cold front advances into Louisiana, moderate winds will keep pollutants well dispersed over much of the sate. Additionally, rain showers and scattered thunderstorms will keep the atmosphere well mixed and limit ozone formation, yielding Good AQI levels. Wednesday, as the front stalls over the Bayou State, winds will weaken, reducing pollutant dispersion. However, rain showers and scattered thunderstorms will continue to reduce ozone production and enhance mixing. Furthermore, regional pollutant carryover from previous days will be low. These conditions will lead to high-Good AQI levels in most cities.
