The highest AQ index in Louisiana (as of 17:00 CST) is currently the Shreveport area. Particle Pollution (PM2.5) is measuring at 44 (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.
Monday, as surface high pressure moves southward over Texas, periods of moderate northerly winds will increase dispersion across Bayou State. However, these winds may gradually transport thin smoke southward into the region, increasing particle levels late in the day. Additionally, lighter winds will reduce dispersion in the evening. These conditions will lead to high-Good AQI levels in most cities. Tuesday and Wednesday, overnight temperatures in the teens to mid-20s over much of the state will produce a strong inversion, confining pollutants to the lower levels of the atmosphere. Furthermore, as surface high pressure settles over the state, winds will remain light through much of the period, allowing pollutants to accumulate. As a result, AQI levels will be low-Moderate in most cities on both days.
