Parched Southern California could get some badly needed rain this weekend to dampen the prospects of another round of killer wildfires.

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.

Millions of California residents were placed under a red flag warning through Thursday amid threats of further fires with looming winds in the forecast, according to multiple reports.
