The highest AQ index in Louisiana (as of 17:00 CST) is currently the Thibodaux area. Particle Pollution (PM2.5) is measuring at 78 (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 Thibodaux 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.
Saturday and Sunday, smoke from regional agricultural burns will increase particle levels in some areas. However, as surface high pressure builds to the north, light northerly to northeasterly winds will gradually disperse pollutants and carry cleaner air into Louisiana. Additionally, cooler temperatures will limit ozone formation. As a result, AQI levels will range from Good to low-Moderate on both days. Monday, as surface high pressure shifts southward over Louisiana, decreasing northerly winds will hinder dispersion. In addition, smoke from regional agricultural burns will continue to contribute to particle levels. Therefore, AQI levels will be high-Good to low-Moderate.
