LOS ANGELES — Winds picked up on Tuesday in Southern California and at least a couple of new wildfires broke out as firefighters remained on alert in extreme fire weather two weeks after two major blazes started that are still burning in the Los Angeles area.

Santa Ana winds are whipping Southern California on Tuesday, sparking fresh fears that progress made fighting wildfires that have scorched over 40,000 acres and left 27 dead could be reversed and more blazes could break out.

Over a week after destructive wildfires erupted in the Los Angeles area, fire crews have made progress with containment and stopped growth of the Eaton and Palisades fires.
