Los Angeles County residents face heightened fire risks this week as strong winds are set to return, prompting new red flag warnings across the region. Firefighters are battling the Palisades Fire and Eaton Fire, which have already burned thousands of acres. Here’s what you need to know about the current situation.
Fire Updates and Weather Warnings
Firefighters gained some ground over the weekend as winds calmed, allowing for increased containment of the Palisades Fire and Eaton Fire. These fires, which started on January 7 during a powerful Santa Ana windstorm, are among the most destructive in California’s history, burning a total of 38,600 acres so far.
However, the relief is temporary. Strong winds will return Monday night, lasting through Wednesday, with a red flag warning in effect. Some areas are also under a Particularly Dangerous Situation (PDS) red flag warning, indicating extreme fire weather conditions beyond standard warnings.
What is a Red Flag Warning?
A red flag warning signals dry and windy conditions that can rapidly spread wildfires. The PDS red flag warning, issued by the National Weather Service (NWS), is reserved for critical fire weather events. This is the fourth time in three months that such an elevated warning has been issued in Southern California.
Wind Forecast Details
Meteorologists predict winds gusting between 20 to 50 mph, with isolated gusts in mountain areas reaching 70 mph. While these winds may not be as intense as last week’s 90 mph gusts, they remain a significant threat.
Firefighters also face challenges in using aircraft to fight the flames. Sustained winds above 40 mph can ground water-dropping planes, limiting their effectiveness in controlling fires in steep and rugged terrains.
Areas Affected
The red flag warning will cover:
- Ventura County mountains and coast
- Malibu and Santa Clarita Valley
- Parts of San Fernando Valley and San Gabriel Mountains
- Inland Orange County and areas of the Inland Empire
The elevated PDS warning, effective from Tuesday at 4 a.m., includes:
- The Grapevine corridor on the 5 Freeway in northern LA County
- Areas from San Fernando Valley into Ventura County, including Ventura, Fillmore, and Simi Valley
- The western Santa Monica Mountains above the coast
Current Evacuations and Fire Threat
As of Monday, 92,000 residents in LA County remain under evacuation orders. Some areas were downgraded to evacuation warnings, allowing residents to return home but remain prepared to leave if needed.
During last week’s windstorm, entire neighborhoods were destroyed, and flames spread quickly due to dry brush and low humidity. Southern California’s hillsides, covered in dry vegetation, remain a major fire risk.
Why Santa Ana Winds Are Dangerous
Santa Ana winds occur when high-pressure air flows toward low-pressure areas, rushing through canyons and mountain passes. This process increases the wind’s speed and lowers humidity, creating the perfect conditions for wildfires.
These winds act like a powerful downhill force, drying out the air as they descend. Combined with already dry fuels, low humidity, and strong gusts, the fire threat becomes critical. Santa Ana winds typically occur from fall to winter, posing a recurring challenge for firefighters.
Firefighter Strategies
Fire crews emphasize the importance of early containment efforts, as these conditions can cause fires to spread unpredictably. Residents are urged to stay informed, have evacuation plans ready, and rely on multiple sources for emergency notifications.
The elevated fire risk continues through Wednesday. With the possibility of flare-ups and new fires, the community’s cooperation and preparedness remain vital.
