The extreme heat poses significant risks, particularly for vulnerable populations such as the elderly, children, and those without access to air conditioning. Prolonged exposure to high temperatures can lead to heat-related illnesses, including heat exhaustion and heatstroke. Urban areas are especially at risk due to the heat island effect, which can trap heat overnight. Popular tourist destinations like Yellowstone, Grand Teton, Bryce Canyon, Zion, and Death Valley are also affected, potentially impacting outdoor activities and increasing the risk of heat-related incidents for visitors.
