Air Quality Alert Message Relayed by National Weather Service Gray ME 350 PM EDT Mon May 18 2026 ...AIR QUALITY ALERT IN EFFECT FROM 10 AM TO 10 PM EDT TUESDAY... The Maine Department of Environmental Protection's Bureau of Air Quality has issued an Air Quality Alert for ozone from 10 AM to 10 PM EDT Tuesday. Ozone levels along the Southwest Coast and Mid-Coast are expected to rise into the Unhealthy for Sensitive Groups range. The Maine Department of Environmental Protection recommends that individuals consider limiting strenuous outdoor physical activity to reduce the risk of adverse health effects. People who may be especially sensitive to the effects of elevated levels of pollutants include the very young, the elderly, those with pre-existing respiratory problems such as asthma, those with heart disease and anyone who is working hard outdoors. It is okay to be active outdoors. But if you experience symptoms such as shortness of breath, coughing, throat irritation or an uncomfortable sensation in your chest please consider limiting the intensity and duration of your outdoor activities. A toll free air quality hotline has been established so Maine residents can stay informed on the air quality situations. The toll free number is: 1-800-223-1196. Additionally the Maine Department of Environmental Protection has the air quality forecast available on the web at www.maine.gov/dep/air/aqforecast.
