The heat dome poses significant risks to public health, particularly for 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 heatstroke. The extreme heat also increases the risk of wildfires in affected areas, particularly in California, Nevada, and Arizona. Residents in these regions are advised to take precautions to stay cool and hydrated.
