Air Quality Forecast

February 23 – February 27: Other than a slight chance of light to moderate rainfall Monday evening into Tuesday morning, conditions this week will be dry and within normal temperature ranges. Expect lows in the mid-50s and highs around 65 degrees throughout the forecast area. The calm winds, high pressure, and stable atmosphere will reduce ventilation of accumulated wood smoke. PM2.5 (smoke) AQIs may therefore reach MODERATE – UNHEALTHY FOR SENSITIVE GROUPS, particularly in the San Lorenzo Valley where woodburning fireplaces and devices for home heating may be more commonly used. Conversely, PM10 (dust) AQIs should remain GOOD. Ozone levels should remain below State standards and therefore ozone AQIs will remain GOOD.
