In the areas that remain open, ignition sources — including campfires and gas stoves — are prohibited and all developed campground and day-use sites will be closed.

“The wildfire situation throughout California is dangerous and must be taken seriously,” Randy Moore, regional forester for the USDA Forest Service Pacific Southwest Region, said. “Existing fires are displaying extreme fire behavior, new fire starts are likely, weather conditions are worsening and we simply do not have enough resources to fully fight and contain every fire.”
