Smoke from the Madre Fire, which has burned about 200 acres above Azusa and was 5 percent contained as of Tuesday morning, has pushed the air quality index to the “Unhealthy” range for areas of the San Gabriel Valley, according to the South Coast Air Quality Management District.
In a statement, SCAQMD advises residents, “Smoke has lingered in portions of the San Gabriel Valley overnight. Areas directly impacted by smoke and ash may experience air quality in the Unhealthy range, or higher.”
Depending on the fire and weather conditions, the areas of the South Coast Air Basin where the smoke may impact include:
- Portions of the San Gabriel Mountains (Forecast Area 15);
- The East San Gabriel Valley (Forecast Area 9);
- Portions of the West San Gabriel Valley (Forecast Area 8);
- Portions of the West San Bernardino Mountains (Forecast Area 36).
