San Luis Obispo County air pollution and health officials are warning the public about unhealthy levels of dust blowing off the Oceano Dunes.
High winds are forecast through the weekend that will cause deteriorating air quality in Oceano and the Nipomo Mesa. High wind times are forecast for 11 a.m. to 7 p.m., with gusts peaking from 1 to 5 p.m.
Very sensitive individuals such as infants, as well as children and adults with existing respiratory or heart conditions, may experience adverse health effects during blowing dust periods, the county Air Pollution Control District warns in a news release.
If blowing dust and sand is visible in the air, county officials recommend all adults and children avoid strenuous outdoor activity, remain indoors as much as possible, and set any heating, air conditioning and ventilation systems to recirculation.
