A persistent heat dome is scorching nine states in the western and southwestern United States, with temperatures exceeding 110°F, posing serious threats to millions. The National Weather Service has issued Excessive Heat Warnings for California, Nevada, Arizona, Utah, Colorado, New Mexico, Texas, Oklahoma, and Kansas. Vulnerable populations, including seniors, outdoor laborers, and those lacking air conditioning, face the greatest risk of heat-related illnesses. Many public cooling centers are overwhelmed in major urban areas. Additionally, fire weather risks are rising in the Intermountain West due to dry and hot conditions that could ignite wildfires from dry thunderstorms. Meteorologists anticipate that significant relief will not occur until later in the week.
