UPDATE, 8:45 p.m.: At about 80 acres, the Swinging Bridge Fire is not contained, but Incident Commander Dave Wilkins said during a briefing to evacuees they are "making good progress on it." Electricity is out to much of the immediate area. Fire officials asked Lower Valley Energy to shut off power because the fire was burning underneath the power poles. Officials said it likely won't return tonight to affected residents. No structures have yet been lost.
UPDATE, 7:35 p.m.: Nearly all residents of Game Creek, Squaw Creek and Porcupine Creek subdivisions have been evacuated from the now officially named Swinging Bridge Fire. Some people with horse trailers are streaming into the subdivisions to load up stock that could be in peril as the fire advances.
The cause of the fire is under investigation.
Fire officials plan to hold a briefing at 8:30 p.m. for evacuees outside Munger Mountain Elementary School. Further updates will be posted to TetonFires.com. The website lists the fire's estimated size at 80 acres.
UPDATE, 6:46 p.m.: An aerial battle is raging against the fire near Swinging Bridge. A reporter on scene counts two helicopters with water buckets, a large bomber and a smaller prop plane are dropping retardant on the fire. A high-flying spotter plane is helping coordinate the attack.
UPDATE: 6:25 p.m.: A large fire retardant-dropping airplane has arrived for the arsenal fighting a wildland fire near Swinging Bridge. The entire hillside above Old Henry's Road is blackened as the fire burns northeast toward Game Creek and Squaw Creek subdivisions and, more slowly, southeast toward Porcupine Creek.
UPDATE, 5:54 p.m.: Residents of Old Henry's Road, Game Creek, Squaw Creek and Porcupine Creek are being ordered to evacuate.
"The best thing for them is to do is evacuate so that we can get into those neighborhoods and protect them," Jackson Hole Fire/EMS Chief Brady Hansen said.
The fire on the east side of the Snake River near Swinging Bridge and Porcupine Creek is growing quickly, but Hansen could not yet provide an estimate of its size. About 30 firefighters were on the scene by 5:45 p.m., he said.
By about 7 p.m., Hansen hopes to be able to hold a briefing for evacuees. One staging area for those evacuated is Munger Mountain Elementary School's parking lot, directly across the highway from the flames.
Eyewitness Mariam Diehl, who lives on the west side of the Snake River across from the fire, said her power went out about 5 p.m. and the fire is moving quickly.
"Scary," Diehl said. "It’s big, spreading fast, it’s really scary. We just saw the first chopper go over with a bucket."
In Game Creek, law enforcement officers are driving door to door to alert residents of the evacuation.
This is a developing story.
