The combination of high temperatures, dry conditions, and strong winds poses a significant fire risk, particularly in areas under red flag warnings such as the western San Gabriel Mountains, Santa Clarita Valley, Santa Susana Mountains, and Santa Monica Mountains. Coastal regions in San Diego and Orange counties are expected to experience temperatures 10 to 20 degrees above normal, increasing the likelihood of heat-related health issues. Inland areas may also see elevated fire risks due to the dry and breezy weather.
