Wildfire Smoke Continues To Cause Unhealthy Air Quality In Many Areas Across Southland

Air quality officials have issued another smoke advisory today for areas of the Southland affected by the ongoing wildfires. Smoke from the rapidly spreading Station Fire near La Canada caused very unhealthy air quality n foothill communities near the fire overnight and this morning.

Wildfire smoke settled into valleys last night near the fires. Smoke will likely linger in these areas until this afternoon when onshore ocean breezes are expected to move smoke across the valleys and into the mountains.

All individuals are urged to exercise caution and avoid unnecessary outdoor activities in any area directly impacted by smoke. This includes areas where residents can see or smell smoke. Unhealthy air quality will occur in areas of direct smoke impact, especially near the fires.  These areas will likely include:

• portions of the San Gabriel Mountains;
• the West San Bernardino Mountains;
• the Santa Clarita Valley;
• the San Fernando Valley;
• Central Los Angeles County;
• the East San Gabriel Valley;
• the West San Gabriel Valley; and
• the Hemet/San Jacinto Area.

Wildfires generate smoke containing numerous air pollutants including fine particulates known as PM10 and PM2.5.

Areas with Unhealthy air quality and those directly impacted by smoke: Everyone should avoid any vigorous outdoor or indoor exertion; people with respiratory or heart disease, the elderly, and children should remain indoors. Keep your windows and doors closed unless it is extremely hot inside. In these cases, seek alternate shelter. Run your air conditioner if you have one. Keep the fresh air intake closed and the filter clean to prevent bringing additional smoke inside.
