A wildifre burning in Nova Scotia has not only forced the evacuation of thousands in Canada, but has sent air quality plummeting in cities across the northeastern U.S. this week.

Tourists in New York City likely took photos against hazy skies this week, with air quality on Tuesday afternoon and evening significantly reduced. 

The National Weather Service office there said Wednesday that clouds would give way to hazy sunshine with another day of smoke from the fires. 

"Air quality alerts are in effect for New Jersey as a result per @NewJerseyDEP," it said.

The office in Mount Holly said air quality concerns would continue in that area on Wednesday, with similar conditions as the smoke lingers. 

"A code orange air quality alert has been issued across southeastern P.A. and all of N.J. Sensitive groups should minimize strenuous outdoor activities," it advised.

A wildfire on Canada's Atlantic coast has damaged around 200 houses and structures and led to the evacuation of 16,000 people. 

Firefighters worked through the night to extinguish hotspots in the fire that started in the Halifax area on Sunday.
