The extreme heat poses significant risks to residents, particularly those in vulnerable groups such as the elderly, children, and individuals with pre-existing health conditions. Prolonged exposure to high temperatures can lead to heat-related illnesses, including heat exhaustion and heat stroke. The NWS advises caution as temperatures remain within advisory criteria despite the gradual cooling trend. Areas like Escondido, which reached 112°F (44.4°C), are particularly affected.
