Forecast Discussion:
In general, ozone levels in Yuma will depend on wind direction. If winds remain out of the south, ozone levels will be lower. However, there may be brief periods of winds out of the west; Tuesday looks to be the main day for that.
Next, PM10 (dust) and PM2.5 (smoke) could be elevated from local activity when morning conditions are calm. There may also be some chances for dust the next couple evenings--either from nearby or distant storms, or breezes from the mountains in southern California.
Overall though, PM10 is forecast in the Good AQI category each day.
Check back again tomorrow morning for the latest!
