The highest AQ index in Louisiana (as of 16:00 CST) is currently the Baton Rouge Area area. Particle Pollution (PM2.5) is measuring at 53 (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 surface high pressure traverses the Bayou State, light and variable winds will reduce dispersion. However, areas of low clouds will limit ozone development, and pollutant carryover from the weekend is low. As a result, AQI levels will range from Good to low-Moderate. Tuesday, calm to light winds early in the day will limit dispersion across Louisiana. However, increasing southerly winds will gradually carry cleaner air into the state as the day progresses. In addition, partly to mostly cloudy skies will hinder ozone formation. Therefore, AQI levels will be high-Good to low-Moderate. Wednesday, despite temperatures warming into the upper-70s, partly to mostly cloudy skies will continue to limit ozone development. In addition, periods of moderate south-southwesterly winds will disperse pollutants, leading to Good to high-Good AQI levels.
