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 Monday.

Meteorologists said there was a chance the winds would be as severe as those that fueled the Palisades and Eaton fires, but that different locations would likely be affected.
