Cooler temperatures and higher humidity resulted in reduced activity on the park's fires Friday compared to earlier in the week. Welcome rainfall which fell across much of the park Friday night and early Saturday morning is expected to dampen fire activity for a period of time. However, recent lightning strikes and a forecast for more thunderstorms Saturday keep firefighters poised for the possibility of new fire starts. The Fire Danger level in Yellowstone remains at Extreme, and fire restrictions are in effect.

Cygnet Fire: 
The Canyon to Norris Road was temporarily closed Thursday night, when hot temperatures, low humidity, and gusty winds prompted the fire to advance across a portion of the utility corridor south of the road, with blowing embers igniting a section of forest north of the road. An inspection of the fire line Friday showed that preparations made to protect the utility poles and power lines were successful. The fire is now estimated at just over 2400 acres. A section of the backcountry along the road corridor, including hiking trails and backcountry campsites, remain closed. This lightning caused fire, located 5 miles southwest of Canyon Village, was discovered on August 10.

Dewdrop Fire:
This lightning-caused fire 9 miles southeast of Canyon Village is nearly 1,100 acres. The Dewdrop and Dewdrop 2 fires have now burned together. When actively burning, smoke from this fire is visible from Dunraven Pass through Canyon Village and throughout Hayden Valley. It was discovered on July 29. 

Range Fire:
This lightning-caused fire 8 ½ miles southwest of Tower Fall is nearly 400 acres. This fire is not threatening any structures or roadways, but at times can produce a significant amount of smoke that may be visible from the road over Dunraven Pass and through the Tower Fall area. It was discovered July 26. 

Other fires and smoke:
Smoke from fires both inside and outside of the park may be visible along several sections of park roadways. Visitors are asked to slow down and use extreme caution while driving where firefighting crews are working along roadways, especially between Norris and Canyon Village.

Thunderstorms with gusty winds and lightning are forecast for Yellowstone on Saturday, with a dry cold front and gusty winds expected overnight. Temperatures are expected to be a bit cooler, and humidity levels higher Saturday than the past few days.

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 roads leading to the park and 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.

24-hour road information is available at 307-344-2117. Fire information is available 24-hours a day by calling 307-344-2580, on the web at http://www.inciweb.org/unit/5382/, or on Twitter @YellowstoneNPS.
