The 'Moderate' air quality levels in Milwaukee, Waukesha, and Green Bay may affect individuals with respiratory conditions, such as asthma or chronic bronchitis, as well as other sensitive groups like children and the elderly. Prolonged outdoor activities in these areas could lead to mild respiratory discomfort. However, most people are unlikely to be affected. Areas with 'Good' air quality, such as Dane and Forest counties, pose minimal to no health risks for the general population.
