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)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: [View the ADEQ Hourly Forecast for Yuma]
Adjustments to the forecast are needed! A low pressure circulation is offshore near San Francisco at sunrise today. The eventual speed (or lack thereof) for that weather system through the Desert Southwest is the main element that is changing both the precipitation and air quality forecasts the rest of the workweek. There are now two windows for rainfall in Yuma, 1) tonight - Wednesday evening and 2) Thursday afternoon - Friday morning. The slow progression of atmospheric instability coupled with adequate moisture means multiple rounds of showers and thundershowers can keep adding to rainfall totals. Between 0.25 and 0.50 inches, with higher amounts are possible. Rain/thundershower movement would follow the counterclockwise rotation of the area of low pressure. Keep an eye out for flash flooding! The National Weather Service has issued a Flash Flood Watch for a broad area stretching from southern California to the southwest corner of Arizona, including Yuma. The effective times of the Flash Flood Watch is Tuesday afternoon - Wednesday afternoon, but please monitor the National Weather Service website for any updates.

When we are talking active weather with rain that usually means great air quality and that is exactly what is being forecasted. The one caveat would be locally gusty winds generated by a stronger thundershower crossing desert land that has not received rain yet. Because there is not an expectation for widespread and organized thunderstorm outflow winds, blowing dust is not a major factor in projected air quality at this time. The active weather this week should have a net benefit to the final daily AQI values.

More updates to come in Wednesday's discussion!
