Current Air Quality & Forecast


Air Quality Forecast

February 22 - February 26:  Following the series atmospheric rivers which affected the west coast earlier this week, a period of dry and stable conditions is expected to last for the next few days.  This, however, will to be short lived as a weak trough forming off the coast will arrive Sunday and bring unsettled conditions early next week.  Chances of precipitation peak on Monday with an associated increase in surface winds.  Temperatures will range from the low 40s to high 60s at the coast and from the low 40s to high 60s inland. Cool temperatures will keep afternoon ozone levels below State standards and thus air quality for ozone will be GOOD.  Low pressure and light-moderate winds should make for good ventilation and therefore AQIs for PM2.5 (smoke) and PM10 (dust) will also be GOOD.
