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 Basile right now. All Louisiana warnings.

The forecaster’s discussion

Written by Louisiana Department of Environmental Quality for Lafayette 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.

Fine particles in micrograms per cubic meter, ozone in parts per billion as an 8-hour average. The index for each hour is EPA’s: the ozone figure is already the 8-hour average the ozone index is defined on, and the particle figure is run through EPA’s NowCast, which is how an hourly PM2.5 concentration becomes an index.

Smoke

NOAA’s analysts have not drawn smoke over Basile in satellite imagery today.

NOAA’s model forecasts near-surface smoke peaking at 1.9 µg/m³ around Wed, 7:00 AM CDT.

Smoke on the radar over Basile

What this means

Moderate

Air quality is acceptable. There may be a risk for some people, particularly those who are unusually sensitive to air pollution.

Who is affected
People who are unusually sensitive to ozone or fine particles.
What to do
If you are unusually sensitive, consider making long or intense outdoor activity shorter or easier.
Index range
51 to 100

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.
