Monday afternoon was busy for San Diego firefighters, as they battled two brush fires in the East County.
The first fire, named the Lyons Fire, sparked just after 1 p.m. near Jamul. The Lyons Fire quickly grew to 250 acres and has prompted evacuations. As of 6:45 p.m., the fire was only 10-percent contained.
Six homes near Lyons Valley Road and Honey Springs Road have been advised to evacuate. An evacuation center has been set up at Jamul Primary School at 14567 Lyons Valley Road. Officials say the evacuations are just precautionary.
The fire started on the side of the road on Skyline Truck Trail. Smoke could be seen pouring from the mountains Monday afternoon.
Cal Fire requested additional resources after the fire jumped from five to 30 acres in the matter of an hour. Planes dropped fire retardant on the flames.
"The mid-slope fire really got up and ran on us fairly quickly," Cal Fire Capt. Mike Mohler said.
According to Cal Fire, no structures are in danger, and no injuries have been reported. The cause of the Lyons Fire is still under investigation.
Meanwhile, another brush fire started around 2 p.m. in Portrero. The fire burned five acres before crews had it surrounded, according to Cal Fire. Officials said one person suffered a minor injury.
