The Berry Fire in Grand Teton National Park has increased rapidly in activity, forcing a closure on Highway 89 between the Yellowstone South Entrance and Lizard Creek Campground.
National Park Service employees have been evacuated and are all safely accounted for according to Yellowstone National Park officials.
The fire is most recently recorded to stretch 16,800 acres. Officials in Grand Teton National Park have been letting it burn for ecological purposes.
The southern entrance to Yellowstone National Park was closed as a result of the Berry Fire earlier last month. The fire was originally started by lightning on July 25.
Officials say that the fire is prompting heavy smoke, falling trees, and other dangerous incidents. The spike in activity was largely due to gusty winds and dry, available fuel.
No structures have been damaged so far. There are currently 96 personnel working on this fire. Crews will continue protection activities and burnout operations to protect Flagg Ranch and the South Entrance of Yellowstone National Park as well as burnout to strengthen holding lines.
Officials say that the weather forecast includes low humidity and winds up to 20-35 mph.
