Forecast Discussion:
This weekend and into next week, ozone is forecast in the Good AQI category each day because of mostly southerly (out of the south) winds. Such winds help to prevent ozone transport from the west.
PM10 (dust) and PM2.5 (smoke) are expected to be mostly locally driven, particularly in the mornings. However, we can't rule out the possibility of dust getting kicked up from gulf-related breezes. Strong gulf breezes may be possible over the weekend--for example, early mornings Saturday and Sunday. Overall though, both PM10 and PM2.5 are forecast in the Good AQI category for now.
Check back again on Monday morning for the next Yuma Air Quality Forecast.
