What to KnowWhere: Miller Ranch Road & Campo RoadSize: 11 acres; 5% containedEvacuations: Lifted Road Closures: Closures on SR-54 and on SR-94 lifted The cause of multiple fires in East County, all located near one another, is being investigated by Cal Fire. The largest of the four, a small brush fire that ignited in Spring Valley along state Route 94 near Campo Road Wednesday afternoon, scorched 11 acres before being halted. Cameras from atop Mount Miguel showed smoke billowing sideways around 2:30 as firefighters gathered at the base of the mountain near Miller Ranch and Campo roads. Firefighting airplanes supported ground crews by dropping fire retardant from above. An evacuation warning was temporarily issued and quickly lifted for an area that mostly encompassed the San Diego National Wildlife Refuge. The fire burned near Steele Canyon High School, but Cal Fire Capt. Mike Cornette said the high school was not in the evacuation zone. By 3:15 p.m., the fire’s rate of spread had been halted and crews had a containment line cut around 5% of the fire. At the time of the fire, temperatures in the area were about 74 degrees and wind gusts were low, which is helpful to firefighters but humidity levels were also at one point below 20%, according to NBC 7 meteorologist Greg Bledsoe. The fire prompted road closures in both directions on state Route and on SR-94, which were lifted around 3:30 p.m. Three other small fires were reported not far away: A brusher burned 1.5 acres in Jamul near Proctor Valley Road and ignited two nearby spot fires A fire of similar size kept choppers busy near Dehesa and Sloane Canyon roads A fourth fire was ignited near Willow Glen Road Cal Fire San Diego tweeted out around 5:20 on Wednesday that all the fires had been stopped, and all evacuation orders and warnings had been lifted. Nobody was injured by any of the fires, officials said. Anybody with information about the cause of the fires is being urged to call Cal Fire’s anonymous tip line at 800-468-4408.
