Wildfire smoke from western Canada is expected to flow into Maine on Tuesday, resulting in a drop in air quality. Air quality levels are expected to be unhealthy for sensitive groups but are not likely to reach the point that the state would issue recommendations for most people to stay indoors. Maine largely avoided Canadian wildfire smoke in late June. “Maine will not be spared this time,” said Martha Webster, air quality meteorologist with the Maine Department of Environmental Protection.
