An air quality alert has been issued for New York City, the Hudson Valley and northern New Jersey through 12 a.m. Monday due to smoke from wildfires in the area.

Wildfires were burning from one end of New Jersey to the other on Friday after one of the driest months on record, leading New York City to issue smoke warnings and forcing farmers to take steps to protect their harvests.

Multiple wildfires in New Jersey prompted a smoke advisory and stretched firefighters to the limits as flames burned from the Pinelands in the central and western parts of the state to the New York City suburbs.
