January 13 to 19, 2017 – Following this week’s earlier storms, a cold core upper level low has settled in over the Central Coast bringing chilly temperatures, good dispersion and crystal clear skies to the area. A beleaguered ridge then attempts to build in over the weekend before being ejected to the east by strong upper level westerly winds early next week. Air quality for PM2.5 and PM10 for most areas should remain in the GOOD category of EPA’s Air Quality Index (AQI). With overnight temperatures in the San Lorenzo Valley dipping into the low 30’s and a weak inversion in place, residential wood burning will increase, especially in areas where storm related power outages persist. This will because AQI’s for PM2.5 to increase into the MODERATE category with overnight peaks into the UNHEALTHY FOR SENSITIVE GROUPS category in neighborhoods where smokey chimneys are present. Residents who must burn wood are encouraged to use best management practices for reducing smoke. These include burning only dry seasoned firewood that is loosely stacked the firebox and minimizing smolder by not dampering down air flow into the firebox.
