The Maryland Department of the Environment has issued a Code ORANGE Air Quality Alert Saturday for the Baltimore City Metro and Annapolis region. Concentrations of fine particulate matter due to wildfire smoke will persist at levels consistent with an Air Quality Index of Unhealthy (Red Alert) to Very Unhealthy (Purple Alert) Friday night into Saturday morning. Air quality begins to improve Saturday afternoon. Code Purple and Code Red Air Quality Alerts mean that air pollution concentrations within the region are unhealthy to very unhealthy for the general population. A Code Orange Air Quality Alert means that air pollution concentrations within the region may become unhealthy for sensitive groups. Sensitive groups include children, people suffering from asthma, heart disease or other lung diseases and the elderly. The effects of air pollution can be minimized by avoiding strenuous activity or exercise outdoors.
