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.

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.

The NWS Los Angeles/Oxnard CA issued a wind advisory at 12:54 a.m. on Wednesday valid for Wednesday between 2 p.m. and 10 p.m. The advisory is for Southern Ventura County Mountains, Interstate 5 Corridor and Eastern San Gabriel Mountains.
