AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)

Forecast Discussion: Weather around Yuma yesterday was a little more active than expected, with thunderstorms in the area throughout much of the afternoon. While there were showers around Yuma, the Yuma MCAS itself did not report any rain. However, it did report haze from a brief period of blowing dust. The PM10 spike as a result of the dust was large, but very quick. PM10 only managed to reach the low-Moderate AQI category due to the dust.

Looking ahead through the forecast, thunderstorm activity is expected to decline over the coming days, lowering the risk of dust. As a result PM10 is forecast to stay in the Good AQI range over the next few days. By the end of the forecast period, thunderstorm activity is forecast to start increasing as the monsoon ridge begins to strengthen back over the four corners region. As a result, we have increased PM10 during the evening hours on Tuesday due to the possibility of thunderstorm outflows moving through the area. However, we did not increase concentrations very much as that is still too far out to have much confidence.

As for ozone, no issues are expected anytime soon. Mostly southerly winds over the next several days will limit any influence from California, which is the primary source of ozone in Yuma. Therefore, we forecast ozone to stay in the Good AQI range through the forecast period.
