San Luis Obispo County air and health officials are warning of potentially unhealthy levels of blowing dust and sand in the Oceano Dunes and Nipomo Mesa areas this weekend.
Blowing sand and dust is forecast to occur from 11 a.m. to 7 p.m. Saturday and Sunday, with the dust forecast to peak from 1 p.m. to 6 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.
County officials recommend that the public reschedule outdoor activities to occur when there is no visible dust. If blowing dust and sand is visible, they recommend that all adults and children avoid strenuous outdoor activity, remain indoors as much as possible, and set any heating and air conditioning and ventilation systems to recirculation.
