Firefighters in New Jersey are reporting “substantial progress” in battling a wildfire that is threatening dozens of structures, one of a number of forest fires they are fighting in the state. The New Jersey Department of Environmental Protection’s Forest Fire Service said Saturday afternoon that the fire in the Pompton Lakes area of Passaic County had been 50% contained.

More than 10,000 residents remained under evacuation orders as the Mountain Fire continued to threaten some 3,500 structures in suburban neighborhoods, ranches and agricultural areas around Camarillo in Ventura County. The blaze, which broke out around 9 a.m. Wednesday, had zero containment and the cause was unknown.
