The extreme heat poses health risks, particularly due to elevated nighttime temperatures in the high 60s to around 70°F, which can prevent the body from recovering. The combination of dry vegetation and gusty winds increases the risk of fast-moving wildfires, especially in areas like the Santa Barbara south coast and mountains, where winds could gust up to 50 mph. Fire departments in Los Angeles and Santa Barbara counties have pre-deployed additional resources to respond to potential fire outbreaks.
