Six-hundred firefighters were spread out across Great Smoky Mountains National Park on Saturday trying to better assess the growing footprint of the deadly Chimney Tops 2 Fire while also working to get the upper hand on a second fire that had covered 750 acres in the park's backcountry.

Some help was contained in the weather forecast, which called for rain showers to develop Saturday night and continue into Monday.

As of Friday night the Chimney Tops 2 Fire had a footprint of 17,109 acres, with all but about 6,000 acres inside the national park and the rest in Sevier County, Tenessee. The fire, which was reported November 23, ripped through Gatlinburg, Tennessee, on Monday night and into Tuesday, leading to 13 deaths and destroying nearly 900 homes, officials said.

"The plan of attack is to continue assessment of roads and trails for total containment of fire perimeter, mop-up and patrol of structures and facilities to minimize further loss, providing for firefighter and public safety," a release from the incident command team said. "There will be air support available, if needed."

While the Chimney Tops 2 Fire was 25 percent contained, the Cobbly Knob Fire spotted earlier in the week and thought to be related to the larger fire measured roughly 750 acres and was 13 percent contained, the team said. It was located inside the park just to the east of the larger fire.

While rainfall Wednesday onto ground burned by the Chimney Tops 2 Fire led to some mud- and rock-slides onto "the Spur" and the Newfound Gap Road that crosses Great Smoky Mountains National Park from Gatlinburg to Cherokee, North Carolina, those have been removed and Park Service officials were working with state and local officials to reopen the roads.
