NANAKULI, OAHU (HawaiiNewsNow) - Fire crews were expected to remain overnight in Nanakuli, where a brush fire has already scorched more than 1,500 acres since Thursday night.
The fire fight included helicopter water drops, which ended at 6 p.m. when the sun went down.
Honolulu Fire Department crews will be protecting homes from the flames overnight Saturday into Sunday.
Officials evacuated several groups of people from Camp Palehua (formerly Camp Timberline) as a precaution Friday night.
HFD said the fire has become increasingly hard to contain on the challenging terrain.
Honolulu Fire Capt. James Todd said there are "windy conditions that just blow the fire, and it can get out of control really quick and out of your reach."
"The valley is like a bowl, and the fire is covering the right side of the bowl and moving around and going to the left side of the bowl, so it's taking out the whole valley systematically and going across it," Todd said.
Crews plan to resume helicopter water drops Sunday morning.
