Effective: Wed September 3, 2025, 4:06 PM
Expires: Wed September 10, 2025, 4:15 PM
The Valley Air District is issuing an Air Quality Alert on September 3, 2025, due to smoke impacts from wildfires in California including the Garnet Fire, the Marmon Fire, the Salt 11-2 Fire, and the TCU September Lightning Complex for San Joaquin, Stanislaus, Merced, Madera, Fresno, Kings, Tulare, and the Valley portion of Kern Counties.

Additionally, older adults and children should avoid prolonged exposure, strenuous activities or heavy exertion, as conditions dictate.
