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 Eunice right now. All Louisiana warnings.

The forecaster’s discussion

Written by Louisiana Department of Environmental Quality for Lafayette and filed with AirNow.

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 low-Moderate over most of the state on both days. Friday, with surface high pressure positioned over the Great Lakes, northeasterly winds will persist, gradually transporting a cleaner air mass into the Bayou State. However, lower wind speeds will reduce pollutant dispersion in the afternoon, and partly to mostly sunny skies will aid ozone production. As a result, AQI levels will remain high-Good to low-Moderate in most cities.

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 Hazard Mapping System analysts drew light smoke over Eunice in satellite imagery today (Wed, 7:00 AM CDT to Wed, 10:00 AM CDT). That is smoke seen from above; it is not always smoke at ground level.

NOAA’s model forecasts near-surface smoke peaking at 2.1 µg/m³ around Wed, 6:00 AM CDT.

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.
