Wildfire smoke causing poor air quality in New England and Ontario.
The New Hampshire Department of Environmental Services issued an air quality action day for parts of the state on Sunday due to expected smoky conditions caused by winds bringing waves of smoke from eastern Canada. The smoke can cause health problems for sensitive individuals, and NHDES recommended limiting time outdoors and strenuous activities. Air quality is expected to improve on Monday when winds are expected to shift and send the smoke away from New Hampshire.
