Air quality has taken a serious hit across the United States as a twofold blow of wildfires in the West and in Canada have sent smoke pouring across large sections of the country — a problem that’s set to linger for days.

Air quality across parts of New Hampshire will continue to be affected by smoke from Canadian wildfires through Tuesday night and into Wednesday.

Continuing smoke from the Canadian wildfires is causing the north country to be under an Air Quality Alert for the third consecutive day.
