Rainfall is expected to reach Los Angeles and Southern California this weekend, bringing the risk of mudslides and fire debris flow.

Much-anticipated rain could be headed to drought-stricken Southern California this weekend -- but rainfall also brings the threat of landslides.

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.

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.

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.

"A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly," the NWS said.

A small number of residents were allowed to return to the devastated Pacific Palisades and Altadena areas and firefighters quickly controlled small blazes that broke out.
