Air Quality Index for Louisiana

The highest AQ index in Louisiana (as of 11:00 CDT) is currently the Lafayette area. Particle Pollution (PM2.5) is measuring at 55 (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 Ozone (OZONE) 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, cool temperatures and lingering clouds will limit ozone formation across Louisiana. Additionally, as high pressure builds to the west, light to moderate northwesterly winds will keep pollutants well dispersed. Therefore, AQI levels will be Good statewide. Tuesday, light and variable winds will hinder dispersion early in the day as surface high pressure approaches the state. In addition, light northerly winds during the afternoon will transport regional smoke from agricultural fires across the central and southern Plains into the Bayou State, increasing particle levels and ozone precursors. As a result, AQI levels will be high-Good to low-Moderate. Wednesday, as the surface ridge of high pressure crosses Louisiana, calm to light southerly winds will limit dispersion and recirculate thin lingering smoke across the state. In addition, mostly sunny skies and highs in the mid- to upper-70s will enhance ozone development. These conditions will result in high-Good to mid-Moderate AQI levels.
