Hot, dry conditions continued to feed trees into the flames of the Berry Fire in Grand Teton National Park/NPS

Wildfires in Yellowstone and Grand Teton national parks in Wyoming continued Monday to complicate visitors' lives, as the South Entrance to Yellowstone remained closed to traffic and smoke was creating health and driving hazards.

While Grand Teton's Berry Fire was continuing to grow and keep Yellowstone's South Entrance closed to traffic, the Maple Fire in Yellowstone was inching towards Madison Junction less than 2 miles away. Causing concern for fire bosses on both fires was the weather forecast: dry, low humidity, and gusting winds.

In Yellowstone, where more than 200 firefighters were assigned to the Maple Fire that was sparked by lightning on August 8, Monday's briefing stated that, "(T)raffic control will be in place on the West Entrance road when needed, and burn-out operations are anticipated to take place along the West Entrance to Madison Junction administrative site road if the fire reaches the Madison River. A nightshift is in place to assist with traffic control and a firefighter presence as needed."

Additionally, inversions at night were expected to send smoke from the 33,000-acre fire down into West Yellowstone.

In Grand Teton, the Berry Fire was approaching 12,400 acres in size. 

"The (South Entrance) road will be reopened when fire danger is reduced and hazardous trees are removed," Monday's briefing from Grand Teton said. "Flagg Ranch Campground and Headwaters Lodge were evacuated on the morning of August 23 due to potential for continued fire growth to the north. The fire is now established across both sides of Highway 89 and burning to the northeast in Bridger-Teton National Forest."
