NANAKULI, Hawaii - Honolulu firefighters say a West Oahu brush fire that burned since pre-dawn on Sunday is 100 percent contained. The fire department says 500 acres burned, and hot spots and smoke are coming from burned areas. 

The call came in at 3:50 a.m. as  a wildland fire behind Nanakuli Sack and Save. A total of 22 Honolulu Fire Department (HFD) units staffed with 53 personnel responded. 

HFD says strong gusty wind conditions, accessibility, and terrain are challenging fire fighters efforts. In Nanakuli, the fire came as close as 100 feet to some homes.

Voluntary evacuations were in effect as no homes are in danger. HFD says if people who live nearby are affected by the smoke, they should leave the house. 

HFD says the fire originated in Nanakuli Valley and branched off into Waianae Valley. Throughout the day, it was an active fire that firefighters battled on multiple fronts, and with the help of the federal fire department.  

The American Red Cross set up an emergency shelter at Nanakuli High School, though it closed later in the day. 

No injuries or damages to residential structures have been reported.
