New Jersey firefighters are still battling nine intense wildfires that have left a teenager dead and the region blanketed in a thick fog of smoke — although Mother Nature’s overnight rains might help quell the blazes.

The massive deadly fire in rural West Milford near the New York border was the largest that still raged Sunday, while smoke-eaters seemed to be getting a handle on suburban blazes in Passaic County’s Pompton Lakes and Englewood Cliffs in Bergen County, reports said.

The West Milford blaze — which began near Greenwood Lake — has consumed several thousand acres in New York and New Jersey and is the most widespread of the nearly 10 fires currently torching the bone-dry Garden State, which is suffering under severe drought conditions, according to The Record.

The fire was completely out of control as of Saturday night, with first responders reporting that they hadn’t contained any of it, the outlet said.

A teenage employee of the New York State Parks, Recreation and Historic Preservation Department became the blaze’s first casualty Saturday when a tree fell on him, according to a Facebook post by the Eastern Dutchess County Fire and Rescue.

Dariel Vasquez, who was just 18, was helping fight a fire in Sterling Forest when he died, a statement from the New York State Police said.

Orange County Executive Steve Neuhas said Vasquez was clearing out trees and shrubs that could have become fuel for the fire when the tree fell, according to the New York Times.

“My prayers go out to his family, friends and coworkers during this difficult time,” Gov. Kathy Hochul said in a statement Sunday.

“I commend his dedication to serving and protecting his fellow New Yorkers, and his bravery on the front lines.”

The flames have left northern New Jersey covered in a throat-clogging, eye-watering haze that stretched from the foothills of the Appalachians to the Hudson River.

But at least some help is on the way, according to Cody Braud, a meteorologist with Fox Weather.

“There’s a weather system just off to the west right now … and that’s going to start moving through late this evening,” Braud said Sunday afternoon.

The rain should start around 8 p.m. Sunday and continue all night — covering the region with about a half-inch of fire-quenching water.

That’s not much. But it could help moisten the dry leaves, parched shrubs and arid soil that’s created the circumstances under which wildfires thrive, the weather expert said.

“The rain is the big story — it should, more than likely, dampen all these adverse effects we’re seeing the last few days,” Braud said.

“We shouldn’t really see much smoke or anything moving around [by the morning].”

There’s another chance for rain overnight Thursday, Braud said. But it likely won’t be very significant.

“It’s just some more much-needed rain on the way,” he said. “It’s nothing super beneficial, but at least it’s something.”

Although the New York City skies began to clear Sunday — especially when compared with their neighbors across the river — an air-quality alert remains in effect for the Big Apple until 12:15 a.m. on Monday, according to AccuWeather.

Aside from two fires in Sterling Forest, New York state workers are also fighting blazes in Ulster and Sullivan counties that have destroyed about 300 to 400 acres and are expected to worse, Hochul’s office said in a statement.

The New Jersey Forest Fire Service and the New York Department of Environmental Conservation Division of Forest Protection and Fire Management will provide an update on the blaze at 3 p.m. Sunday, the agency said in a post on X.
