The National Weather Service has provided a detailed timeline of when rain is expected to hit Los Angeles and Southern California this weekend.

There is a 10% to 20% chance of flash flooding and landslides in some recently burned areas of Los Angeles County, forecasters say, including for the Palisades and Eaton fires.

A fire broke out Wednesday night along the 405 Freeway in the Sepulveda Pass near the Getty Center, burning about 20 acres and spurring an evacuation warning.

A particularly dangerous situation red flag warning is in place from noon Monday to 10 a.m. Tuesday local time for a large portion of Ventura and Los Angeles counties.

Local media reports that these winds could create "dangerous" fire weather conditions that could last all week.

The National Weather Service has issued another rare Particularly Dangerous Situation warning in anticipation of Monday's Santa Ana wind event.

The Hughes Fire near Castaic, north of Los Angeles, was 24% contained on Thursday afternoon, according to Cal Fire.

The particularly dangerous situation alert is relatively new to Southern California but has been issued before the recent wildfires that have caused devastation across LA County.

The first significant rainfall in several months will spread across Southern California this weekend, giving a badly needed sip of water to an area parched by drought and devastated by multiple raging wildfires.

The National Weather Service issued a flood watch effective from 4 p.m. Sunday to 4 p.m. Monday for areas in or near burn scars created by the Palisades Fire, Eaton Fire, Hughes Fire and Bridge Fire, the latter blaze of which burned 56,000 acres last fall.

Dozens of people are believed to have died in the Palisades and Eaton fires, which have burned down whole swaths of communities
