AQ Index for Louisiana

Air Quality Index for Louisiana

The highest AQ index in Louisiana (as of 5:00 CDT) is currently the Monroe area. Particle Pollution (PM2.5) is measuring at 49 (Good). This means air quality is satisfactory, and air pollution poses little or no risk.

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.

Friday and Saturday, as a frontal boundary stalls across Louisiana, calm to light winds will reduce pollutant dispersion through most of the period. However, periods of heavy rainfall and scattered thunderstorms will aid mixing and inhibit ozone development. Therefore, AQI levels will be Good to low-Moderate on both days. Sunday, as the next cold front approaches from the north, clouds and showers will continue to limit ozone formation over the Bayou State. However, calm to light winds will lead to pollutant build-up, yielding high-Good AQI levels in most cities.
