RABUN COUNTY, Ga. -- Several residents are being told that it's no longer safe for them to stay inside their homes as crews work to contain a wildfire that's burning closer to them.

Now locals are holding a prayer vigil for rain to calm a fire that grew by 50 percent literally overnight.

Officials issued a voluntary evacuation for residents of roughly 25 homes on Coleman River Road and Nichols Branch Road in the Persimmon Community only recently. A pre-evacuation was also in issued for the Plumb Orchard community and Tate City.

"In the last 36 hours it's been really hectic," Pastor Scott Cates said Saturday. "Things escalated quickly."

A shelter was opened at Liberty Baptist Church where he is pastor.

Meanwhile, Jenna Charles drove more than 30 miles to drop off donations.

"It just was a burden on my heart," Charles said. "Whenever I first heard of the fires, I started praying for rain."

And she's not the only one feeling the call to help.

"We've been getting home calls all day long from people all over the Southeast," Pastor Cates said. "I've even gotten messages of support from Brazil."

At this point, they've received so many donations that they can't take any more fire officials said.

The fire threatening the homes is part of the Rock Mountain fire in the Chatooga River District of the Chattahoochee National Forest. Officials said they think the cause of this fire was arson, and are looking for a person who was seen driving a dark blue SUV.

As of Friday, the wildfire had burned about 900 acres on both sides of the Tallulah River Road near Tate City, but that number grew to more than 4,000 acres by Sunday.

Luckily, no homes have been destroyed so far.

But the steep and rugged terrain are making things difficult for firefighters.

The Rabun County Sheriff's Office and U.S. Forestry Service officials are asking people to stay out of the area so that crews can do their jobs "as quickly and safely as possible." They have already closed Tallulah River Road and the Forestry Service plans to close a section of the Appalachian Trail later Saturday for safety concerns,

A shelter has been set up at the Liberty Baptist Church at Bridge Creek Road and Davis Gap Road for displaced residents. Bedding, food and necessary supplies will all be provided.

Forestry officials have issued a complete fire ban in all parts of the Chattahoochee-Oconee National Forests. Smoke and haze have also lingered over the metro-Atlanta area thanks to winds flowing from the north, causing some issues for sensitive portions of the population.

The fires have sent smoke in the metro Atlanta area:
