Gatlinburg, TN (WOKI) Lightning from a recent summer storm is to blame for the Flint Gap Fire burning in the Great Smoky Mountains National Park.

Park fire officials and fire investigators making that announcement Tuesday say the exact date of the lightning strike is unknown, but the fire burning near Hannah Mountain was reported to the park on August 26 and is currently 17 acres in size.

The park says there is low potential for significant growth over the next few days due to the current high humidity, lack of strong winds, and shaded terrain.

Park officials add that lightning caused wildfires are relatively rare in the Smokies with most occurring during the month of August.

Currently, the park says there are ground crews and a “Type 3” helicopter working on the fire. Crews are monitoring fire activity and working to identify areas where they can safely confine and contain the fire. No structures are threatened.

As of Tuesday, the park said Parson Branch Road and some park trails and backcountry campsites are closed due to the potential fire danger.

GSMNP officials advise checking the park website for road closures and other updates before visiting the park.
