Discussion for February 8 to 13 – A strong ridge of high pressure is present over the West Coast causing “summer in winter” weather conditions including clear skies, offshore flow and well above normal temperatures. Strong offshore winds over the region have pushed land based particulate matter and other pollutants out to sea leaving blue skies and pollution levels for PM2.5, PM10 and ozone generally in the GOOD air quality category of EPA’s Air Quality Index (AQI). Currently, longer range models keep the Central Coast high and dry through the week, with no rain in the forecast. In the San Lorenzo Valley Smoke Sensitive Area (SLV SSA), AQIs for PM2.5 will continue to be higher than the region as a whole with localized areas reaching the MODERATE category due to residential wood smoke. Wood burners can minimize the impact of their smoke on neighbors by following best management practices for burning including using dry seasoned wood, not over packing the fire box and building a hot efficient fire.
