The National Weather Service office in Los Angeles has issued a Particularly Dangerous Situation (PDS) Fire Weather Warning for much of the Santa Ana wind corridor in Los Angeles and Ventura Counties, effective through Tuesday. The PDS Warning is extended through Wednesday for the Susana Mountains.

 

Santa Ana winds, originating from the mountains of the same name in Southern California, bring hot, dry air from the east. While they can occur year-round, they are most common during the cooler months of fall and winter.

 

Please be fire weather aware over the next few days across the mountains and valleys. Let's do our part to create one less spark! 👊 #CAwx #FireWeather https://t.co/HQfKmNEFca
