Firefighters in Immokalee continued battling two brush fires Wednesday night.
One produced lots of black smoke, and the other threatened homes earlier in the day, officials said.
Crews from the Immokalee Fire Control District responded to a fire between Rose Avenue and East Main Street about 12:45 p.m. after a deputy called it in, said Immokalee Fire Battalion Chief Thomas Cunningham.
The brush fire, first burning a couple of acres, quickly grew to 5 acres over the afternoon.
"It's dry, low humidity, the wind," Cunningham said. "It's like a perfect storm almost."
Because illegally dumped tires were scattered throughout the area, the fire also produced "real black smoke" and would take "copious amounts of water" to be put out, he said.
No homes were in danger.
Crews from the Seminole Fire Department assisted the six Immokalee Fire units at the scene, Cunningham said.
The North Collier Fire Control and Rescue District also helped battle the fire with a command unit and a brush truck, said district spokeswoman Christina Silverman.
While firefighters still were working to put out the first blaze, units were called to work a second brush fire that sparked up near the 3700 block of Justice Circle about 2:40 p.m.
That fire grew from about 3 acres to 5 acres, Cunningham said. The fire was about 50 yards away from homes earlier in the day, but as of Wednesday night, no homes were in danger, according to Cunningham.
Crews from the Florida Forest Service assisted with bulldozers and a helicopter. North Collier Fire sent two brush trucks, a battalion chief and a water tender, Silverman said.
"They're calling out quite a few units," Cunningham said.
By 8:40 p.m., the fire near Justice Circle still was 60 percent contained.
