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 Buckeye right now. All Arizona warnings.

The forecaster’s discussion

Written by Arizona Department of Environmental Quality for Phoenix and filed with AirNow.

Ozone yesterday reached the Good AQI category, and this will continue the next few days. There will be some variation depending on when more cloud cover and rain comes, and the highest chance for Phoenix to see rain would now be later Wednesday. However, a ridge of high pressure will continue building later this week, and daily values are forecast to reach the Moderate AQI category starting Friday.

Yesterday PM10 reached the Moderate AQI category due to local activity in West Phoenix. Today will also have a daily Moderate AQI because of morning local activity. There could be some outflow winds that come from the southeast today, but it is not expected to impact West Phoenix as much. Through Thursday, the trend of larger concentrations in the morning followed by possible evening increases from outflow winds and storms will continue. Starting Friday, storm chances decrease and PM10 will be impacted by local activity, especially in the mornings. PM2.5 will have similar trends.

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 Buckeye in satellite imagery today.

NOAA’s model forecasts near-surface smoke peaking at 1.3 µg/m³ around Tue, 9:00 PM MST.

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.
