The Zero AIFederal Aviation Administration slowed flights to and from the New York City area and Philadelphia Wednesday amid reduced visibility caused by wildfire smoke from Canada. More than 100 wildfires are burning across the Canadian border in Quebec and Ottawa and the smoke has drifted into the U.S., particularly in the Northeast. 

All flights to LaGuardia Airport in New York have been paused, according to the FAA. Departures have been slowed. John F. Kennedy International Airport is experiencing arrival and departure delays, the airport tweeted, but the FAA has not yet paused or slowed flights from the facility. 

Flights to nearby Newark Liberty International Airport in New Jersey have been slowed, the FAA said. The agency said traffic is also slowed from the East Coast and Midwest bound for Philadelphia International Airport because of the reduced visibility. 

"The agency will continue to adjust the volume of traffic to account for the rapidly changing conditions," an FAA official said.

Wind and haze have been reported in New York, Washington and Philadelphia, according to the FAA's air traffic report. 

The National Weather Service issued a Marine Dense Smoke Advisory for boaters along parts of New Jersey's coast. The weather agency warned of visibility issues. 

Both New York and New Jersey issued air quality health advisories for Wednesday. The advisories showed air quality was "unhealthy" across much of the two states.
