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.

Two wildfires ignited early Tuesday in San Diego, California's Department of Forestry and Fire Protection said. The Lilac Fire had burned about 20 acres at a moderate rate of speed and was zero percent contained, Cal Fire’s San Diego department said in a statement posted on social media.
