Moderate to high UV Index levels across Arizona pose risks of skin damage and eye irritation for those exposed to the sun, particularly during midday hours. Residents in areas like Naco and Sierra Vista, where UV Index values are highest, should take extra precautions. Prolonged exposure without protection can lead to sunburn and increase the risk of long-term skin conditions, including skin cancer. Vulnerable groups, such as children and individuals with fair skin, are at higher risk.
