Yellowstone National Park Fire Update - Friday 9/25/09  11 am


Probable Start Date: September 13, 2009
Reported: September 23, 2009     
Cause: Lightning Estimated Size: 250 acres                             

LOCATION: Five miles west of the Bridge Bay Campground and the northwest shore of Yellowstone Lake.

OVERVIEW: The lightning-caused fire is burning in a flat area of mature lodgepole pine forest. As of late Thursday afternoon, it was estimated at 250 acres in size and growing as expected. Firefighters are monitoring the fire and actively managing small areas of concern. 

RECENT ACTIVITY AND EXPECTATIONS: The fire continues pushing to the south toward the power line and the Grand Loop Road. Helicopters will be using bucket drops to cool off the southern head and the west flank of the fire to keep it away from the road and power line corridor.

Smoky conditions are present and expected to continue during the afternoon peak burning period. Visitors are reminded to reduce driving speeds due to smoke along the roadways. No road closures are anticipated at this time.

The fire is expected to grow in the next 24 hours, especially during the peak afternoon burning period. Winds today are expected from the northwest and will continue moving the fire southwesterly, although typical prevailing winds are from the south-southeast and may change at any time.  Warm temperatures and low humidity are expected for the day.

IMPACTS TO VISITORS AND AREA RESIDENTS: Smoke and flames will be visible from the Grand Loop Road at times. Check at park visitor centers or backcountry offices for the current status of hiking trails and backcountry campsites in the area. No sites or facilities are currently closed due to fire activity.

MANAGEMENT STRATEGIES: Yellowstone National Park is a fire-adapted ecosystem. Fire plays an important role in maintaining the health of the area’s wildlife and vegetation. Most fires occurring in the Greater Yellowstone Area are caused by lightning. Firefighters continue to monitor the Arnica Fire by air, from the ground, and from the Mt. Washburn Fire Lookout. The fire is being managed in order to protect people and property, enhance the area’s natural resources, and effectively use available firefighting resources.  

Fire updates will be issued as conditions warrant. They will be posted to the web at  http://www.inciweb.org/ and http://www.nps.gov/yell/parknews/newsreleases.htm, and will be recorded on the park’s 24-hour fire information line at 307-344-2580.
