Stable weather conditions and a slight amount of precipitation resulted in little growth activity on the fires in Yellowstone National Park on Monday. Lightning from the same isolated thunderstorms that brought the scattered rain showers also created a small new fire in the burn scar of the 2010 Beach Fire approximately 3 miles northwest of West Thumb. No significant fuel sources are available in that area for the fire to spread, and management of that fire start is being determined today. Warm and dry weather with increasing winds and an impending cold front passage forecast for the next few days brings the chance for increased fire activity. The Fire Danger Level in Yellowstone remains at Extreme, and fire restrictions are in effect. Firefighters and equipment from Yellowstone, along with Saguaro National Park (Arizona), Big Thicket National Preserve (Texas), Gallatin National Forest, Montana Department of Natural Resources and Conservation, Park County Rural and Paradise Valley Fire Departments (Montana) are assisting on the fires burning in the park.
Cygnet Fire: This lightning-caused fire 5 miles southeast of Norris Junction is now estimated at 1450 acres. Firefighters continue efforts to protect a utility corridor south of the road between Norris and Canyon in case the fire reaches the area. A section of the backcountry trails and campsites along the Canyon-to-Norris road have also been closed. Smoke from the fire may be visible along several sections of park roadways throughout the week. Visitors are asked to use extreme caution while driving where firefighting crews are working along roadways. This fire was discovered on August 10.
Range Fire: This lightning-caused fire is located 8 ½ miles southwest of Tower Fall. It was discovered on July 26 and is nearly 170 acres. This fire is not threatening any structures or roadways, but will likely produce a significant amount of smoke that will be visible from the road over Dunraven Pass and possibly through the Tower Fall area.
Other Fires: The Dewdrop Fire is located 9 miles southeast of Canyon Village. It was discovered on July 29 and is estimated at just under 140 acres. Firefighters also continue to monitor the Agate, Dewdrop 2 and Camera fires, all of which are less than one acre.
Weather: Continued warm daytime temperatures, increased winds and a cold front passage on Wednesday along with low humidity and dry fuels combine to create critical fire conditions and potential for significant fire growth.
Fire Restrictions: Any fire which can produce an ash is prohibited in the backcountry. Smoking is prohibited along all trails and anywhere in the backcountry. Smoking is allowed in vehicles and along roads, near buildings, and in developed campgrounds or picnic areas if you are standing in an area at least three feet in diameter where nothing on the ground will burn. Campfires are allowed only in established fire grates or fire rings in picnic areas, campgrounds and housing areas. Charcoal grills are okay in these same areas as well. You can use portable stoves and lanterns which use propane, white gas, kerosene, or jellied petroleum for fuel anywhere in the park.
Impacts to visitors and area residents: All park entrances, roads, campgrounds, lodging, stores, and other visitor services are open. Backcountry closure details are available at any park Visitor Center or Backcountry Office. Backcountry information can also be obtained by calling 307-344-2160.
