A housing additon on Doble Road at SE 152 is being evacuated at 4:25 p.m. said Kristy Yager, Oklahoma City spokeswoman.
She said police officers are going door to door telling people about the fire and urging them to leave.
"It was a real slow burning fire that has rekindled all of the sudden," Yager said.
She said there are six fire rigs there fighting the blaze.
Firefighters are also at SE 149 and Hilltop Road fighting that flareup.
