In spite of cooling temperatures, several air quality advisories remain in effect for San Luis Obispo County.
Through today and Thursday, air quality in eastern San Luis Obispo County is forecast to be unhealthy for very sensitive persons due to an increase in ozone concentrations.
“Ozone concentrations are forecasted to increase significantly in the afternoon and evening hours in interior valleys and mountains of San Luis Obispo County; impacting Carrizo Plains, Red Hills and nearby communities,” reads an alert issued by the county Air Pollution Control District. “People that are sensitive to air pollution should limit time outside during afternoon and early evening.”
Also, an odor warning remains in effect for the Nipomo Mesa through Sunday. The strong odors are due to decaying organic materials from White Lake in the Nipomo Mesa area, the agency warns.
Never miss a local story.
“As White Lake dries and shrinks, organic material from the lake bottom becomes exposed and decays, resulting in unpleasant odors,” states an advisory. “Sensitivity to such odors is common.”
Strongest odors have been reported in the vicinity of Highway 1 at Fowler Lane near Lopez High School.
