WAYCROSS, Ga. -- Strong winds on Thursday afternoon and evening pushed a massive wildfire over fire lines in several locations in southeast Georgia, forcing the evacuation of 15 to 20 homes in Ware County

Forestry officials said the fire jumped lines at Suwannee Chapel Road and was spreading toward the west, about 15 miles south of Waycross.

Residents along Suwannee Chapel Road from Eight Mile Post Road to Swamp Road and Swamp Road from Suwannee Chapel to Jim Cox Road were ordered to evacuate and the roads was closed.

Several side roads were also closed to traffic.

Helicopters and more than two dozen tractor-plow units are trying to control this portion of the fire.

Fire also crossed fire lines moving out of the refuge in another area north of the Swamp Road spot closer to Waycross. Fifteen to 20 structures were threatened by this fire, but no structures were reported to be damaged.

Fire also broke through fire lines in one other spot on the west side of the refuge. Resources have been dispatched to try to contain this area over before it continues to grow.

In the past two days, the fire has burned an additional 12,652 acres near the northwest edge of the Okefenokee National Wildlife Refuge.

Further south, the Bugaboo fire is pushing hard against fire lines on the west side of the fire, east of Fargo. Officials report firefighters place have held their own and no fire has spread outside of the fire lines.

With extremely dry conditions and low humidity being experienced in Ware and surrounding counties, the Ware County Board of Commissioners voted unanimously Thursday to adopt a moratorium on the use of fireworks, including sparklers, beginning immediately and lasting 60 days.

County Commissioner Joe Cornelius III, who has spent time battling the blaze as a volunteer firefighter, proposed the moratorium.

Central and south Georgia are so dry that more than half of the state faces an "extreme" fire danger -- the most severe rating -- the commission said. Everywhere else, the threat is considered "high" or "very high."

In the past month, firefighters have battled dozens of small wildfires across Georgia while focusing most of their efforts on the huge blaze in the Okefenokee that has burned more than 481,450 acres -- or 752 square miles -- in southeast Georgia and northern Florida.

Forestry officials said this fire, called the Big Turnaround Complex Fire, is the largest in Georgia's recorded history.
