The combination of high temperatures, dry conditions, and strong winds poses a significant fire risk across Southern California. Areas under red flag warnings include the western San Gabriel Mountains, Santa Clarita Valley, Santa Susana Mountains, and Santa Monica Mountains. These conditions increase the likelihood of wildfires, particularly in regions with dense vegetation and dry terrain. Coastal areas, including San Diego and Orange counties, will experience temperatures 10 to 20 degrees above average, further exacerbating fire risks.
