Some residents in Pukalani were forced to evacuate their homes Thursday as firefighters battled a brush fire.

Crews responded at 2:21 p.m. to an area behind Akalani Loop. Fire officials reported difficulty getting to the fire as it burned in a 100-foot deep gulch that could not be easily accessed by fire trucks.

During the height of the blaze, flames came within 30 feet of homes, threatening about a dozen structures. Residents were evacuated for a short time and have since been let back into their homes.

Fire officials say winds spread the fire quickly downwind, and pineapple and green sugarcane fields helped keep them from advancing further.

The fire has scorched an estimated 200 acres so far.

As of 7:15 p.m., all of the active fire has been knocked down by helicopters and firefighters are now entering the mop-up stages.

Crews will remain on scene throughout the night to monitor the area for flare-ups.

No structures were damaged and no one was hurt. The cause has not yet been determined.
