REMARKS:Tuesday through Thursday, moderate southerly winds will effectively disperse pollutants, and scattered thunderstorms will aid mixing. However, these winds will also transport Saharan dust into Louisiana, increasing particle levels. Therefore, AQI levels will be Good to low-Moderate in most locations on all three days.
