NAHUNTA, Ga. (AP) — A volunteer firefighter died battling a wildfire in northern Florida while more than 120 homes have been destroyed in southeast Georgia and thousands more remain threatened by two large blazes, one of which investigators suspect was sparked by a foil balloon touching power lines, officials said Friday.

An unusually large number of wildfires are burning this spring across the Southeast, where scientists say the threat of fire has been amplified by a combination of extreme drought, gusty winds, climate change and dead trees still littering some forests after being toppled by Hurricane Helene in 2024.

In northern Florida, the Nassau County Sheriff’s Office said Friday that volunteer firefighter James “Kevin” Crews suffered an unspecified medical emergency while suppressing a brush fire. Crews was rushed to a hospital where he died Thursday evening, according to a news release posted to social media.

“Kevin was the epitome of courage and dedication,” Hilliard Volunteer Fire Chief Jerry Johnson said in a statement. “His sacrifice will never be forgotten.”

After getting a firsthand look at firefighting efforts in southeast Georgia, Gov. Brian Kemp told reporters that state officials believe 87 homes burned in rural Brantley County this week are the most ever destroyed by a single wildfire in the state’s history.

An additional 35 homes have been lost to a larger fire burning in sparsely populated Clinch and Echols counties near the Florida state line, Kemp said. That blaze has burned about 50 square miles, an area twice the size of Manhattan.

Kemp said officials suspect the Brantley County was sparked by a foil party balloon that touched live power lines, creating an electrical arc that ignited the ground. He said investigators suspect the larger fire started with a man welding a gate outside.

Spread across more than 11 square miles and still growing, the Brantley County blaze was 15% contained Friday, the Georgia Forestry Commission said. An estimated 4,000 homes in the county were under evacuation orders Friday, said commission spokesperson Seth Hawkins.

“There’s no way to stop this fire,” Kemp said. “They’re having to contain the flanks and the back of it and then, hopefully, we get a change in the weather.”Firefighters are battling more than 150 other wildfires in Georgia and Florida that have sent smoky haze into places far from the flames, triggering air quality warnings for some cities.
