As a huge wildfire continues to burn in central New Jersey on April 24, smoke from the blaze is expected to reach residents in New York City some 60 miles away, prompting an air quality alert.

The air quality will be unhealthy for sensitive groups and residents will start to smell and see smoke, New York City Emergency Management predicted. The alert covered Manhattan along with the Bronx, Kings, Queens, Richmond, Nassau, Suffolk, Westchester and Rockland.

The Jones Road wildfire, which started the morning of April 22 in southern Ocean County, New Jersey, burned 13,250 and was 50% contained as of the evening of April 23. Officials said that while firefighters had made progress on containing the blaze, it was expected to keep burning until the area sees a soaking rain, likely not until the end of the week.

Heavy smoke from the fire was affecting visibility in the neighboring townships, where residents have been allowed to return to their homes after about 5,000 people were evacuated.
