December 9 to 14 – An unsettled pattern will continue into next week with storm systems expected to pass through Saturday and again starting Monday night. These passing systems should scour out air pollution, keeping air quality for PM10 and PM2.5 over most areas in the GOOD category of EPA’s Air quality Index (AQI). In the San Lorenzo Valley, air quality can be expected to be slightly degraded compared to other areas with AQIs for PM2.5 continuing to reach the MODEARTE category due to residential wood smoke.
