Santa Ana winds will continue whipping through Southern California through Thursday, sparking fears that progress made fighting wildfires that have scorched over 40,000 acres and left 28 dead could be reversed and more blazes could break out.

LOS ANGELES (AP) — Parched Southern California was forecast to face more dangerous winds on Wednesday but could get some badly needed rain this weekend, dampening the prospects of another round of deadly wildfires though even a small amount of precipitation could could create new challenges like toxic ash runoff.

As winds across the Southern California area are calmer than their peak and firefighters are making progress, the threat to the fire-weary region remains with Santa Ana winds expected to continue in the coming days.
