The most serious red flag fire weather warning has been issued by the NWS for swaths of L.A. and Ventura counties starting before dawn Tuesday.

Los Angeles County stands at a critical juncture this week, with weather officials warning of an incoming Santa Ana wind event that could worsen fire conditions in areas already devastated by recent blazes.

This is the third PDS warning issued within 14 days in the greater Los Angeles area, which is "unprecedented" for the region, according to the National Weather Service.

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

After a weekend of reprieve allowing fire teams to continue making progress battling the deadly infernos burning in Los Angeles County, Southern California now faces another round of fire-fueling Santa Ana winds.

The “particularly dangerous situation” was in effect for an area that includes parts of Los Angeles and Ventura counties.

According to Azusa police, a man who has admitted to setting a fire at a park has been arrested as the investigation continues.

Firefighters quickly extinguished several brush fires that erupted Monday in Southern California amid windy and dry conditions. The extreme fire weather is raising the risk of new wildfires like the two major blazes that started two weeks ago and are still burning in the Los Angeles area.

Firefighters continue to fight fires in Los Angeles as strong winds returned to the region, spurring on a new fire near San Diego.

Forecasters warn that dangerous winds will buffet Southern California for at least two more days as new wildfires broke out and a pair of major Los Angeles-area blazes burned for a third week.
