Canadian Wildfires Bring Unhealthy Smoke to Northeast and Beyond.

Smoke from wildfires in Canada's Quebec province has caused "unhealthy" air quality in parts of the Northeast, including the New York City metro area. The smoke can cause coughing, shortness of breath, and other immediate effects, even in healthy people, and can aggravate chronic heart and lung conditions. The smoke is different from the last few weeks as it is traveling near the Earth's surface. The smoke was pushed southward into the Northeast by strong winds around low pressure near the New England coast. The pattern is expected to remain largely unchanged for the next few days.
