Notice:
The Maricopa County Air Quality Department has issued a No Burn Day for today, 7/9/2023. Full Details >
Forecast Discussion:
The past couple days, ozone has continued to be the primary pollutant of concern. On Friday, several monitors in the Phoenix area exceeded the federal health standard. While on Saturday, it was just one monitor near downtown Phoenix. Looking ahead, similarly calm and sunny conditions today and tomorrow will bring potential for ozone to continue reaching the Unhealthy for Sensitive Groups AQI category. Therefore, there are Ozone High Pollution Advisories in effect for Sunday and Monday.Beginning Tuesday, we are forecast afternoon winds to become a little more persistent out of the west, which we are forecasting to provide just enough ventilation to lower ozone into the upper Moderate AQI range. As for particulates, we are forecasting PM10 to reach the low Moderates during the workweek. This is due to elevated concentrations during the calm, morning hours with increased dust-generating work activities. As for PM2.5, we don't anticipate any significant issues. PM2.5 is forecast to stay in the Good AQI range through the forecast period.
