El Niño conditions played a part in a series of raging brush fires over the weekend. According forecasters, it's because of the dry conditions.  
The process refers to a short term period of warm ocean surface temperatures leading to warmer than usual weather and much dryer conditions.
Along the west side of Oahu, the National Weather Service sees that as a potential problem.  

"With El Niño comes drought usually and so that dries out all the vegetation and we can get an out of season active period in terms of brush fires,"  Kevin Kodama, hydrologist, National Weather Service, said. "For the Leeward areas, you're really getting out of a chance of any sort of meaningful rainfall for that side of the island anyway. It's the driest time of the year."

"The big risk factors are sort of all of these unused former agricultural lands but all this grass," Clay Trauernicht, wildland fire specialist, University of Hawaii, said. 

According to researchers and the Honolulu Fire Department, some fires are preventable. 

"About 75 percent of these fires are accidental but that leaves a significant portion that's still intentional so addressing those is a challenge,"Trauernicht said.

So far in 2019, HFD says it has responded to seven significant brush fires on Oahu. 

"It should allow folks in those communities to start to get ready and realize the threat is there and they can do something about it now to minimize the impact,"  Captain Scot Seguirant, HFD, said. 

To help prevent wildfires, Seguirant recommends residents cut their brush and vegetation to at least 30 feet away from their homes.
