A large junkyard fire in Waiawa on Oahu is sending thick black smoke over the H-1 freeway and Pearl City, which is bad news for drivers and nearby residents.

• Seven Honolulu Fire Department companies plus two federal fire trucks are fighting the blaze at the ABC Junkyard on Lehua Avenue.
• Drivers on the H-1 say the smoke is making it hard to see the road.
• The fire covers under an acre but burns deep inside a huge debris pile, so it will take a long time to put out.
• Nobody knows what chemicals are in the smoke drifting over Pearl City.
• The same junkyard has already racked up more than $400,000 in fines for health and permit violations, and its owners are fighting a state order to shut it down.

Outlook: Crews expect a slow fight as the pile smolders from underneath, and the fire adds weight to the state's push to close the yard.
