UPDATE 4/19/16 6:45 p.m.

Shenandoah National Park confirms that the Rocky Mount Fire covers more than 2,000 acres. Earlier reports the fire was more than 3,000 acres were from another agency, and the National Park Service was not able to confirm that number. Shenandoah National Park assures WHSV they are actively working to fight the fire.

More than 200 crews joined the effort today. Hotshot crews from as far as New Mexico have been brought in to help. Crews are being aided by two helicopters, a plane and eight fire engines.

Firefighters at the edge of the fire line told WHSV's Katie Caler, they are working hard to keep the fire from spreading to private property.

Crews spent the day working on containment lines, also helped by a helicopter using a water basket to drop water on the flames.

Rockingham County Fire and Rescue crews are also helping, making sure homes are safe.

"At this point, we don't feel anything is immediately threatened, we do have some fire that's backed down into the Beldor area, we have trucks on the scene and are working with that to manage that," said Rockingham County Fire and Rescue Chief Jeremy Holloway.

If you live close to the fire area and are concerned, a public information number has been set up. That number is 540-442-9111. If the fire comes within a few hundred feet of your home, Holloway recommends calling 911.

Holloway says there are things you can do to keep your home safe.

"Safe up around your home, clean out, you know blow leaves away, try to get, shut up your buildings your garage doors and things like that's some of the ways you can do to help us."

Shenandoah National Park says the fire is up to 2,094 acres in size.

Fire crews are working to contain a growing wildfire in the Shenandoah National Park near Elkton. The fire can be seen from WHSV's Charlie O'Baugh Skycam, and many in the Valley have sent pictures of their view of the smoke.

Right now, Skyline Drive is closed in the area between mile 65 (Swift Run Gap) and and mile 79 (Loft Mountain). The National Park Service has also closed four miles of the Appalachian Trail, as well as a few additional trails in that area to keep hikers away from the fire.

Since Saturday, the fire has grown to approximately 700 acres. The cause of the fire is under investigation but the National Park Service believes it was caused by humans. It confirmed to WHSV today, this was not a planned or controlled burn.

"It is very steep terrain, wooded with a lot of mountain laurel so that is part of the reason why the fire is burning pretty hotly, because leaf litter and mountain laurel are, cause fire to move through an area pretty quickly," said Ranger Sally Hurlbert with the National Park Service.

Hurlbert added, "We're trying to suppress the fire but as we do it, we're trying to do it in a minimal way so what that means is we try to use existing rails if possible as fire lines, we try to use natural waterways and creeks to help contain the fire."

Fire leaders tell WHSV they're still working to contain this blaze. Tomorrow, hotshot crews from Augusta County and New Mexico are expected to join the effort.
