The heat wave poses significant risks to residents in the Inland Empire, particularly vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Prolonged exposure to high temperatures can lead to heat-related illnesses, including heat exhaustion and heat stroke. The lack of relief during overnight hours may exacerbate these risks, especially for those without access to air conditioning. Outdoor workers and individuals engaging in strenuous activities are advised to take extra precautions.
