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 Bossier City right now. All Louisiana warnings.

The forecaster’s discussion

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

Tuesday, upper-level high pressure will reduce vertical mixing in the atmosphere. In addition, mostly sunny skies and temperatures around 90-95F will enhance ozone development, while calm to light south-southeasterly winds will limit dispersion. Therefore, AQI levels will be high-Moderate in Baton Rouge and New Orleans, with low- to mid-Moderate AQI levels expected elsewhere. Wednesday, southeasterly winds will strengthen, aiding pollutant dispersion in the Bayou State. However, partly to mostly sunny skies and warm temperatures will continue to support ozone production. Thus, AQI levels will be low- to mid-Moderate statewide. Thursday, increasing clouds and scattered thunderstorms in southern Louisiana will reduce ozone production. However, light southeasterly winds will limit pollutant dispersion. These conditions will yield high-Good to low-Moderate AQI levels.

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 Bossier City in satellite imagery today (Tue, 7:00 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 near-surface smoke peaking at 4.1 µg/m³ around Wed, 12:00 AM CDT.

Smoke on the radar over Bossier City

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.
