Air quality in the New York City metro area continues to decline as smoke from wildfires in New Jersey and New York lingers in the air. A health advisory is in effect in New Jersey for unhealthy air quality.

New York City had a weekend of mostly blue skies marred by acrid smoke and air-quality advisories after a series of brush fires, fueled by extremely dry conditions, erupted around the region. People sensitive to pollution were advised that the air quality through Sunday could be at unhealthy levels because of smoke and particulate matter.

A New York parks employee died battling one of a number of wildfires in New Jersey and New York amid dry conditions that have prompted air quality warnings in both states, authorities said Sunday.

Air quality is still poor in New York City Sunday morning as fires rage on in New York and New Jersey, according to the National Weather Service. An air quality alert remains in effect in New York City and the lower Hudson Valley through Sunday night,
