Air Quality Alerts Issued Across Southern California Due to Wildfire Smoke and Ozone Pollution
Air quality alerts have been issued across Southern California as wildfire smoke and elevated ozone levels push air conditions into unhealthy ranges. The National Weather Service (NWS) has warned that the combination of fine particle pollution (PM2.5) from wildfire smoke and ground-level ozone poses significant health risks, particularly for vulnerable populations. Affected areas include the Greater Los Angeles region, the San Fernando and San Gabriel Valleys, Santa Clarita Valley, the San Gabriel and Santa Susana Mountains, the Highway 14 corridor, and the Inland Empire region. Additionally, the Imperial Valley, including El Centro, Calexico, and Brawley, is experiencing elevated ozone levels. The alerts are expected to remain in effect through Thursday evening, with conditions influenced by fire behavior, wind patterns, and sunlight-driven chemical reactions.
