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 at about 4:30 p.m., blackened a large swath of the ridge before being brought under control at about 4:30 p.m.

The fire reignited at 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 School, according to Hono­lulu Fire Department spokes­man Capt. David Jen­kins.

Jenkins said no 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 at about 10:35 a.m., blackened a large swath of the ridge, Jen­kins said.

No other 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 from the lower campus to the 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 move through the valley.

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