A fire along Waahila Ridge that was earlier contained by Honolulu firefighters has flared again Friday evening due to shifting wind conditions.

The blaze, first reported above the University of Hawaii faculty housing on Dole Street about 4:30 p.m., blackened a large swat of the ridge before being brought under control about 4:30 p.m.

The fire reignited about 6:30 p.m. in the lower Manoa area and moved deeper into the valley along a steep area below Waahila Ridge and adjacent to Noelani Elementary, according to Honolulu Fire Department spokesman Capt. David Jenkins.

Jenkins said neither Noelani nor any structures in the area are threatened.

Thirteen fire companies with 48 HFD personnel remain on scene and are fighting the front of the fire with hoses and other apparatus.

One firefighter suffered a leg injury and was transported to an area hospital.

The cause of the fire and the acreage involved have not yet been determined.

The fire, first reported above the University of Hawaii campus about 10:35 a.m., blackened a large swath of the ridge, Jenkins said.

No injuries were reported and no evacuations were required.

UH and nearby St. Francis School are both on spring break. A St. Francis preschool class was moved to the lower to upper campus area as smoke began to drift past.

Toward the late afternoon, the fire began to creep down the slope toward the vicinity of the St. Francis campus, where firefighters were waiting with hoses.

Jenkins said the school was not threatened and that the fire would be extinguished as it advanced within range of the hoses.

St. Francis head of school Sister Joan of Arc said she spent several anxious hours watching the smoke and flames moving through the valley.

“I’ve never seen a fire come across like this,” she said. “Practically the whole mountain is black.”
