Firefighters were slowly making progress in their battle to contain the inferno that has razed swathes of Los Angeles' Pacific Palisades neighborhood to the ground, but still-spreading flames threatened communities in the populous San Fernando Valley on Sunday.

After a weekend of reprieve allowing fire teams to continue making progress battling the deadly infernos burning in Los Angeles County, Southern California now faces another round of fire-fueling Santa Ana winds.

Winds have died down in recent days, but another Santa Ana wind event is expected early next week. There are still air quality concerns, particularly closer to the burn areas. LOS ANGELES - Calmer winds over the last few days have allowed firefighters to drastically increase the containment of two major wildfires burning in Los Angeles County.
