Federal officials say that a forest fire that broke out Monday on the Allegheny National Forest is only 40 percent contained as of Tuesday afternoon.

The fire is estimated at 62 acres, according to Allegheny National Forest Public Affairs Officer Christopher Leeser.

It was 40 percent contained as of 3 p.m.

“The Sugar Bay Wildfire is located in the Bradford Ranger District of Allegheny National Forest and is burning on Forest Service land on the eastern side of Allegheny Reservoir just north of Sugar Bay and west of Polly’s Run,” Leeser explained.

He said that ANF staff are “actively engaged in establishing firelines and mitigating safety hazards.”

Additionally, the Glade VFD and the U.S. Army Corps of Engineers are “providing boat operators and boats to ferry wildland firefighters to the fire.”

“Wildland firefighters will monitor the fire and continue to work toward 100 percent containment in the coming days,” he said.

Officials ask the public to stay out of the fire area and stress that the safety of the public and firefighters is the “highest priority.”

Motorists are asked to use “vehicle headlights and extreme caution” if driving on smoke-covered roadways as well as yield to fire equipment.

Leeser said that no evacuations had been ordered and no structures were threatened as of 3:30 p.m.

“The cause of the fire is under investigation,” he said. “The Pennsylvania Department of Conservation and Natural Resources – Bureau of Forestry is leading the investigation.”
