According to the Maine Department of Environmental Protection, ground-level ozone concentrations will be climbing in Maine on Thursday, July 28, and are expected to reach unhealthy levels. Unhealthy levels are expected along the coast from Kittery through Reid State Park. Moderate levels of ozone are possible in the Midcoast, including the high elevations of Acadia, the Downeast coast as well as the western interior region.

At elevated ozone levels, children, healthy adults who exert themselves, and individuals suffering from a respiratory disease such as asthma, bronchitis or COPD can experience reduced lung function and irritation. When this happens, individuals may notice a shortness of breath, coughing, throat irritation, and/or experience an uncomfortable sensation in their chest.
