Some homes were evacuated due to a brush fire near Savonna and Gatlin boulevards, the St. Lucie County Fire District says.
The 3 acre fire began in the 2900 block of SW West Calabria Circle but jumped Gatlin Boulevard.
The Florida Forest Service was called and responded.
SW Gatlin Blvd from SW Port St Lucie Blvd to SW Savona Blvd is closed east and westbound until the smoke clears.
The fire district says the fire has been contained.
