AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Thursday, lingering Saharan dust will continue to increase particle levels; however, light to moderate southerly winds will gradually transport a cleaner air mass into Louisiana. Furthermore, isolated thunderstorms, especially in southern Louisiana, will increase mixing in the atmosphere and reduce ozone formation. As a result, AQI levels will be Good to low-Moderate statewide. Friday and Saturday, light to moderate south-southeasterly winds will continue to transport a cleaner air mass into Louisiana. In addition, scattered showers and thunderstorms throughout the state will increase mixing in the atmosphere, and partly cloudy skies will continue to reduce ozone formation. Therefore, AQI levels will be Good in most cities on both days.
