Thursday's band of strong storms brought down trees and knocked out power throughout Warren County.
The Allegheny National wasn't exempt.
"During the afternoon of July 26, 2012, the Allegheny National Forest experienced a severe storm that caused moderate to high levels of downed trees across the Forest," the ANF said in a statement. "Public and employee safety is our highest priority in assessing and managing the aftermath of the storm."
Forest employees are currently assessing damage and clearing trees from forest roads, trails and campgrounds, the statement said. "Most key roads have been cleared and made passable and trail assessments continue across the forest."
While no evacuations were required, ANF Spokesperson Kathy Mohney said in an email to the Times Observer on Friday that "there was a family stranded in a disabled vehicle on the forest during the middle of the storm, they had cell coverage and were able to make contact with our office so we did have personnel respond to the scene to assist them."
The ANF also reported that the Marienville Ranger Station remains closed, and will remain so for the duration of the weekend, due to the lack of electric and telephone service.
As for the trails, the Timberline ATV trail is closed but the Marienville ATV, Rocky Gap and Willow Creek trails have all been "cleared of any storm damage and are open to the public," according to the statement.
The ANF said that assessing the damage will continue through the weekend and they caution hikers to be aware that they may encounter trees across trails.
All campgrounds are open but some services are limited due to power outages. "The Kinzua Wolf Run Marina remains open, also with limited services due to lack of power," the release said.
