According to the South Coast Air Quality Management District, winds from the west on Saturday and Sunday brought “unhealthful” smoke and airborne particulates from the Woolsey and Hill fires into most of the Los Angeles area. Thankfully, however, “Persistent offshore Santa Ana winds throughout Sunday and Monday will help clear some of the remaining smoke from the Northern San Fernando Valley and the LA metropolitan area,” making our local air quality much better today.
That said, however, the Woolsey fire is far from contained, and the SCAQMD warned that unhealthful air conditions could return again later for most or all of the LA area:
Overall, meteorological conditions may continue to bring smoke into portions of the South Coast Air Basin. Impacts will be the most widespread earlier in the day on Sunday but will continue to decrease throughout the day and into Monday in all areas except the Western San Fernando Valley and Northwest Coastal LA County. Air quality may reach Unhealthy levels or higher in areas directly impacted by smoke.
Areas of direct smoke impacts and Unhealthful air quality may include portions of:
- Los Angeles County: 1 (Central Los Angeles County), 2 (Northwest Coastal LA County), 3 (Southwest Coastal LA County), 4 (South Coastal LA), 5 (Southeast LA County), 6 (West San Fernando Valley), 7 (East San Fernando Valley), 8 (West San Gabriel Valley), 9 (East San Bernardino Valley), 10 (Pomona-Walnut Valley), 11 (South San Gabriel Valley), 12 (South Central Los Angeles County), 13 (Santa Clarita Valley), and 15 (San Gabriel Mountains)
- Orange County: Areas 16 (Northern Orange County), 17 (Central Orange County), 18 (North Coastal Orange County), 19 (Saddleback Valley), 20 (Central Coastal Orange County), and 21 (Capistrano Valley).
- Riverside County: Areas 22 (Corona/Norco) and 23 (Metropolitan Riverside)
- San Bernardino County: Areas 32 (Northwest San Bernardino Valley), 33 (Southwest San Bernardino Valley), 34 (Central San Bernardino Valley), 35 (East San Bernardino Valley), 36 (West San Bernardino Mountains), and 37 (Central San Bernardino Mountains).
In any area impacted by smoke: If you smell smoke or see ash due to a wildfire, limit your exposure by remaining indoors with windows and doors closed or seeking alternate shelter, and avoiding vigorous physical activity.

Finally, as you might expect, the entire Los Angeles area remains under a “No Burn” status today, prohibiting wood burning fires either indoors or outdoors.
