Friday, Saturday and Sunday are Wood Stove Curtailment Days. Wood stove burning is prohibited unless you are burning seasoned wood in a registered EPA-compliant wood stove with phase two emissions control technology or better. For more information on registering your wood heating device please contact NSAQMD at 530-832-0102. Friday, January 9 and Saturday, January 10: As a ridge of high pressure aloft builds over the northern Sierras, atmospheric mixing will decrease. In addition, morning and evening temperature inversions will confine pollutants near the surface. Therefore, despite easterly winds aiding dispersion each afternoon, AQI levels will be mid-Moderate on both days. Sunday, surface high pressure east of Portola will produce calm to light easterly winds that will allow pollutants to accumulate. Furthermore, clear skies and cold morning temperatures will generate an inversion, confining pollutants near the ground. These conditions, combined with day-to-day carryover, will keep AQI levels mid-Moderate. Monday through Wednesday, as an aloft ridge of high pressure strengthens over northern California, atmospheric mixing will be reduced. Furthermore, calm to light easterly winds will limit dispersion each day, leading to high-Moderate AQI levels on all three days.
