The highest AQ index in Louisiana (as of 8:00 CDT) is currently the New Orleans 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 Lake Charles 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.
Friday and Saturday, calm to light winds will reduce dispersion and allow pollutants to linger over the region. However, as a frontal boundary moves into Louisiana from the north and stalls, showers and thunderstorms will develop across much of the state during each afternoon, increasing vertical mixing and hindering ozone development. As a result, AQI levels will be high-Good to low-Moderate on both days. Sunday, scattered showers and thunderstorms will continue to limit ozone development, especially across the northern half of the state. However, light to moderate southerly winds will gradually transport a thin plume of Saharan dust into southern Louisiana. These conditions will keep AQI levels high-Good to low-Moderate.
