MADISON COUNTY, Va. (CBS19 NEWS) -- Certain residents of Madison County are being encouraged to evacuate due to an ongoing wildfire.

The Virginia Department of Forestry says the Madison County Sheriff’s Office is encouraging residents north of 681 Finks Hollow Lane to leave.

The Quaker Run Road fire has now burned about 2,480 acres, including 550 inside the Shenandoah National Park.

Fire crews are working on additional firelines around buildings on Finks Hollow Lane, though at this time, no structures have been damaged.

Once the fire is contained, DOF says crews will need at least two weeks to make sure it is completely out.

The Rapidan Tract of the Rapidan Wildlife Management Area is closed until further notice.

In the national park, officials say the Whiteoak Canyon and Old Rag trails are open but they are being impacted by intermittent dense smoke, which may reach very unhealthy levels.

As these trails do require prolonged exertion, people are being advised to avoid them if they may be sensitive to smoke.

The Graves Mill Trail from the intersection with the Staunton River Trail to the Rapidan Fire Road and all of Wilhite Wagon Trail are closed.

Additionally, the power line that supplies the Big Meadows area has been de-energized due to firefighter safety.

However, the Big Meadows Wayside, the visitor center and the campground are still open and using generators. Sunday was the last day of the season for the Big Meadows Lodge.

And the Madison County  Board of Supervisors has issued a burn advisory, which asks all residents to refrain from any kind of outdoor burning.
