Firefighters are battling a 5-acre wildfire off Becker Road and Palma Street, according to the Florida Forest Service.
Nothing is threatened at this time, the agency said.
The Saint Lucie County Fire District is also on scene.
The Forest Service said vegetation is very thick and a firefighting bulldozer is needed to stop the fire from spreading.
The Forest Service says new wildfires keep popping up because winds are drying out the moisture from yesterday's rain.
