Aug 27, 2013 - The Associated PressYELLOWSTONE NATIONAL PARK -- Another day of scattered thunderstorms is expected in Yellowstone National Park, helping keep a lid on five wildfires burning in the park.
The fires have shown moderated behavior in recent days thanks to the storms that bring cooler temperatures and increased humidity.
Cooler weather continues to help keep fires in Yellowstone under control, allowing park officials to reopen the Mud Volcano area north of Fishing Bridge.
The Mud Volcano and other areas along the Yellowstone River have been closed for more than a week because of the Alum Fire.
Some trails, picnic areas and road pullouts remained closed Monday.
The Alum Fire has burned about 12 square miles. The fire is only a few hundred yards from the Grand Loop Road but isn't growing much.
The fires have burned a combined 18 square miles. But they haven't affected any of the main visitor areas in the park and have been allowed to burn for the most part.
The Yellowstone area is among the first in Wyoming to get winter-style weather, with cold weather and snowstorms not uncommon in September.
