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.

The National Weather Service issued a warning of a “particularly dangerous situation” for parts of Los Angeles and Ventura counties from Monday afternoon through Tuesday morning.

With parts of Los Angeles County still smoldering from wildfires, the expected rain this weekend would seem like a welcome relief. But how the rain falls could make the difference between a disaster respite or a disaster repeat.

Southern California is about to get its first significant rainfall in months, bringing desperately needed relief after dry conditions and hazardous winds fueled a series of wildfires in January. The rain could start as early as Saturday afternoon and last through Monday night with the heaviest rain coming on Sunday,
