REMARKS:Monday, moderate southerly winds will aid pollutant dispersion in Louisiana. However, these winds will also transport smoke from fires burning in Mexico and Central America into Louisiana, increasing particle levels. Therefore, AQI levels will be high-Good to low-Moderate. Tuesday, light winds early in the day will limit dispersion, and southerly winds developing in the afternoon will bring additional smoke into Louisiana. These conditions will lead to low-Moderate AQI levels in most cities. Wednesday, southerly to southeasterly winds will strengthen, aiding pollutant dispersion. However, smoke from fires in the Yucatan Peninsula will continue to impact the region. Furthermore, mostly sunny skies will enhance ozone formation, especially in the southeastern portion of the state. As a result, AQI levels will be high-Good to low-Moderate.
