POMPTON LAKES, N.J. (AP) — Authorities say one of several wildfires burning in New Jersey is threatening dozens of structures, but no evacuations were immediately ordered.

The New Jersey Department of Environmental Protection’s Wildfire Service said Saturday morning that the fire in the Pompton Lakes area of ​​Passaic County had burned 100 acres (40 hectares) and threatened 55 structures. The fire caused the closure of the right lane of northbound Interstate 287, officials said.

The Forest Fire Service was battling the blaze with fire trucks, ground crews and a helicopter capable of dropping 350 gallons (1,325 liters) of water, officials said. The structures were being protected by local fire companies, they said.

Another wildfire burning in the Bethany Run area on the Burlington and Camden county line in Evesham and Voorhees townships was reported to be 90 percent contained.

A fire along the Palisades Interstate Parkway in Englewood Cliffs in Bergen County, across the Hudson River from New York, was reported to be 40 percent contained and not threatening any structures.

Firefighters reported 75 percent containment of the Pheasant Run wildfire in the Glassboro Wildlife Protection Area in Gloucester County.

The National Weather Service has issued a red flag warning, saying gusty winds and low humidity could help fires spread quickly.

New Jersey has not received measurable precipitation in more than a month, the weather service said, setting a new record.
