UPDATE:

The Honolulu Fire Department said the wildland fire above Mililani Mauka was about 700 acres and 30% contained Tuesday night.

HFD will suspend operations at 4:30 p.m. Tuesday as the fire continues to burn in a remote, mountainous area inaccessible to ground units. The main portion of the fire continues to move east on the ridge above Waikakalaua Stream.

HFD said its drone team conducted a fire watch starting at sundown. Another air reconnaissance is planned at 7 a.m. Wednesday.

The Hawaii National Guard supported fire suppression efforts Tuesday with a CH-47 Chinook helicopter. The crew made 25 drops and flew a total of 7.6 flight hours while assisting the Honolulu Fire Department with the Mililani Mauka fire. The Guardsmen dropped about 45,000 gallons of water today and will support HFD and DEM tomorrow.

Anyone who may be affected by the smoke should shelter in place or a place with air conditioning, HFD said. Anyone experiencing difficulty breathing should call 911 immediately.

1 p.m.

The Hawaii Department of Land and Natural Resources says the fire above Mililani Mauka is now estimated to be about 400 acres.

During a flyover, a manager from the Division of Forestry and Wildlife observed the fire burning in heavy timber and through native vegetation, including ohia and koa trees.

Helicopters continue to conduct water drops to douse the flames, DLNR said in a news release, with tens of thousands of gallons of water. The fire is not currently impacting state lands.
