LOS ANGELES (AP) -- Winds are pushing smoke from the San Diego County wildfires across neighboring counties, and pollution authorities say air quality may reach unhealthy levels for people with sensitivities.
At the height of this week's wildfires, winds out of the northeast were blowing smoke offshore.
But the South Coast Air Quality Management District says winds Friday are blowing from the south and smoke could affect all of Orange County, central, northwest and coastal areas of Los Angeles County, and the Lake Elsinore and Temecula Valley areas of Riverside County.
The district says some of the smoke may be from the accumulation over the ocean being pushed back over land by the return of onshore flow.
The district advises people to avoid unnecessary outdoor activities in any area directly impacted by smoke.
