The highest AQ index in Louisiana (as of 12:00 CST) is currently the Shreveport area. Particle Pollution (PM2.5) is measuring at 58 (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, smoke from localized agricultural fires will impact particle concentrations, primarily across southeastern Louisiana. In addition, periods of light southerly winds will reduce dispersion, while an evening temperature inversion traps pollutants near the ground. These conditions will yield mid-Moderate AQI levels in Baton Rouge, with low-Moderate AQI levels elsewhere. Tuesday, the temperature inversion will persist during the morning hours, confining pollutants at the surface. However, west-southwesterly winds will strengthen throughout the day as a weak cold front passes to the north, aiding dispersion. Therefore, AQI levels will be high-Good to low-Moderate in most cities. Wednesday, patchy morning fog will promote particle formation, while a morning inversion will reduce low-level mixing. Additionally, calm to light southerly to southeasterly afternoon winds will inhibit dispersion. As a result, AQI levels will be low-Moderate in most locations.
