Weather conditions are improving Wednesday as firefighters continue to battle a still-growing wildfire that has burned at least 13,250 acres in southern New Jersey since it ignited on Tuesday, prompting about 5,000 evacuations and briefly shut down part of the Garden State Parkway. The fire started inside the Greenwood Forest Wildlife Management Area in Ocean County Tuesday morning and was 50% contained as of Wednesday evening, the New Jersey Forest Fire Service said. The cause is under investigation and a damage assessment is underway. …The fire is expected to grow even as firefighters make progress on containment. “This could very well end up being the largest wildfire in New Jersey in 20 years,” LaTourette said. Despite its large size, the fire destroyed a single commercial building in Ocean County and torched some nearby outbuildings and vehicles, but no homes were harmed, according to LaTourette.
