Air Advisory Issued as Smoke from Northern California’s Fires Blankets Mendocino County

August 6, 2021 4:00 p.m.: Due to the active fires in northern California and stagnant meteorological  conditions, expect widespread haze and smoke for most of Mendocino County for the next few days. Currently most of the smoke from the surrounding wildfires remains elevated over the county.  However, due to fluctuating wind directions and a high pressure ridge over California, the smoke aloft  may fall to the surface bringing “Unhealthy” air to the area. Currently air monitors show particulate  matter concentrations in the “Unhealthy for Sensitive Groups” for most parts of the County and  “Good” to “Moderate” for the coastal areas.

Meteorological conditions are forecast to remain more of the same. Expect smoke impacts to continue  in Mendocino County. Fire weather conditions with persistent high pressure may bring impacts of  “Unhealthy” air and smoke accumulation to valley areas. There could be a slight break to the smoke  impacts this Sunday and Monday. Air quality for coastal areas are expected to remain in the “Good” to  “Moderate” level. While surrounding wildfires are active, expect unpredictable smoke impacts to air  quality followed by multiple periods of some relief through the next few days.
