A particularly dangerous situation has been declared in Los Angeles and Ventura counties as strong Santa Ana winds, potentially reaching 80 mph, create extreme wildfire conditions.
The National Weather Service (NWS) in Los Angeles has issued a rare Particularly Dangerous Situation (PDS) alert due to the anticipated hazardous fire weather and critically dry conditions. This type of warning is uncommon, occurring once every three to five years in the state. A significant concern is the potential for rapid fire spread, prompting such a rare alert.
At least one wildfire, known as the Franklin Fire, has already erupted under these red flag warnings. Located in Malibu near Pepperdine University, the fire has spurred evacuations overnight. The NWS reports that wind gusts over 50 mph are exacerbating the situation, alongside humidity levels that are dangerously low, making it easy for fires to ignite and spread rapidly.
The areas most at risk include those from the mountains northeast of the Santa Clarita Valley to the eastern valleys of Ventura County and extending south through the coastal areas of Ventura County. The regions of Calabasas, western Santa Monica, and Malibu are exceptionally vulnerable, experiencing some of the strongest winds.
Warnings are in effect through Wednesday, covering regions from east of San Luis Obispo to the Mexican border. The PDS for Los Angeles and Ventura counties will remain effective until Tuesday afternoon, as the current wind conditions persist. The expected wind gusts can cause significant damage, including downed trees and power lines, creating more hazards and potentially leading to power outages.
The cause of these treacherous wind conditions is linked to a strong high-pressure system over the Great Basin, which generates east-to-northeast winds across Southern California. These winds accelerate when funneled through mountain passes and canyons, increasing their intensity.
The combination of these winds with the dry status of the region perpetuates the high risk of wildfires. Historically, Santa Ana winds typically commence in the morning, but this event marks a deviation, starting instead in the afternoon.
Authorities stress the importance of vigilance among residents, who are advised to stay informed through reliable channels for alerts. The nature of the winds and current conditions means that any new fires will likely spread quickly, necessitating immediate response to evacuation orders.
Residents are urged to remain alert and prepared as the dangerous Santa Ana winds continue to threaten Southern California. With the potential for rapidly spreading wildfires, it is crucial to heed official warnings and be ready to act swiftly.
