The extreme heat poses significant risks, especially for vulnerable populations such as the elderly, young children, outdoor workers, and those without air conditioning. High humidity levels will exacerbate the heat's effects, making it harder to cool down. Beachgoers face hazards from large waves, strong rip currents, and potential coastal flooding, which could impact low-lying areas, walkways, and parking lots. Inland areas with lower humidity and strong wind gusts, particularly near the Grapevine and southwestern Santa Barbara County, are at heightened risk for wildfires.
