The highest AQ index in Louisiana (as of 12:00 CDT) is currently the Lake Charles 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 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.
Sunday, despite light and variable winds hindering dispersion across Louisiana, low pollutant carryover in the wake of widespread rainfall will limit particle levels. In addition, partly to mostly cloudy skies will hinder ozone development. Therefore, AQI levels will be Good to high-Good. Monday and Tuesday, light southerly winds will gradually transport thin smoke over the Gulf into the Bayou State. In addition, decreasing coverage of showers and thunderstorms will reduce atmospheric mixing. Meanwhile, partly to mostly cloudy skies will continue to limit ozone formation. These conditions will result in high-Good to low-Moderate AQI levels due to particles on both days.
