Alerts in force
An Air Quality Alert is issued by the National Weather Service on behalf of a state or local agency when pollution is expected to reach a level that harms health. An Air Stagnation Advisory means the air will not move enough to clear what is already in it.
None are in force near Beauregard Parish right now. All Louisiana warnings.

The forecaster’s discussion
Written by Louisiana Department of Environmental Quality for Lake Charles and filed with AirNow.
Tuesday, widely scattered showers and thunderstorms will aid atmospheric mixing during the afternoon and evening. However, periods of sun and highs in the mid- to upper-90s will continue to promote ozone formation. Additionally, light northeasterly winds will allow thin smoke to linger over the region. These conditions will yield high-Good to mid-Moderate AQI levels. Wednesday and Thursday, as a weak front departs to the south, increasing northeasterly winds will aid dispersion. However, these winds will also transport thin regional smoke into the state, keeping particle levels elevated. Furthermore, increasing sunshine and temperatures in the low- to mid-90s will be conducive to ozone development. Thus, AQI levels will range from high-Good to mid-Moderate on both days.
Hour by hour
NOAA’s air quality model could not be read for this point just now. It runs twice a day and covers the lower 48, Alaska and Hawaii.
Smoke
NOAA’s Hazard Mapping System analysts drew medium smoke over Beauregard Parish in satellite imagery today (Tue, 8:00 AM CDT to Tue, 10:00 AM CDT). That is smoke seen from above; it is not always smoke at ground level.
NOAA’s model forecasts no measurable smoke near the ground here over the next two days.

Category descriptions are the Environmental Protection Agency’s own.
What these numbers are. An index beside a monitor’s name is a measurement, published hourly by AirNow and preliminary until the operating agency certifies it. A category for today or tomorrow is a state or local agency forecaster’s own forecast for a reporting area. An hourly index is NOAA’s air quality model on a five-kilometer grid, not a reading from any instrument. Where a town has no monitor within reach, only the model figures appear, and the page says so.
