By Nathan Frandino and Lisa Richwine LOS ANGELES (Reuters) -Firefighters raced to contain the frontiers of two Los Angeles wildfires that burned for the sixth straight day on Sunday, taking advantage of a brief respite in hazardous conditions before high winds were expected to fan the flames anew.

Even before powerful winds fueled fires that have scorched more than 10,000 homes and other structures across Los Angeles County since Tuesday, the region’s urban trees were already in trouble

Potentially strong winds returning could push flames toward the world famous J. Paul Getty Museum and the University of California, Los Angeles.
