What Are PDS Red Flag Warnings?
PDS red flag warnings are rare and signify extreme fire weather conditions that could result in rapid and uncontrollable wildfire spread. The warnings were briefly dropped on Tuesday due to calmer-than-expected winds but were reinstated as forecasts predicted increased gusts for Wednesday.
High Winds Raise Alarm
While Wednesday’s winds are not expected to match the intensity of last week, they remain strong enough to spark concern. Wind gusts across higher elevations could exceed 50 miles per hour, while widespread lower elevations may also experience gusts up to 50 mph. Such conditions pose a significant risk for new fires, which could quickly spread out of control.
The NWS has confirmed that while the PDS warning will continue to cover the Eaton Fire area, winds in the Palisades Fire region are expected to remain milder than initially feared.
Affected Areas
The following regions are under the PDS red flag warning:
- Western San Gabriel Mountains (I-5 Corridor)
- Southern Ventura County Mountains
- Santa Susana Mountains
- Ventura Valleys (including Simi Valley, Moorpark, Santa Paula, and South Mountain)
- Western Santa Monica Mountains
- Western San Fernando Valley (Highways 118 and 210 from Porter Ranch to San Fernando)
- Calabasas
- Agoura Hills
- Ventura County Coastal Plains
Meanwhile, regular red flag warnings are expected to expire across much of Southern California by 6 p.m. PT Wednesday.
Looking Ahead: Improving but Still Dry Conditions
As the week progresses, conditions are expected to improve:
- Thursday: Winds are forecasted to subside, with gusts reducing to 30 mph. The remaining red flag warnings are anticipated to expire.
- Weekend: Cooler and more humid air is expected to move into the region, offering some temporary relief from the ongoing dry conditions.
However, a critical concern remains: no rainfall is forecast for at least the next seven days. Southern California, which typically sees its wettest month in February, is likely to experience below-average rainfall through early February. The ongoing dry spell underscores the region’s vulnerability to wildfires, as vegetation remains parched and highly flammable.
Community Preparedness
Residents in affected areas are urged to remain vigilant. Recommendations:
- Avoiding any activities that could spark a fire, such as outdoor burning or the use of machinery that produces sparks.
- Keeping an emergency kit ready and having a plan in place for quick evacuation if necessary.
- Staying updated through local news and official channels for the latest fire weather information.
While Southern California braces for another day of heightened fire risk, the hope is that improving weather conditions later this week will provide much-needed relief. However, the lack of rainfall continues to be a significant challenge for a region prone to wildfires. Residents are encouraged to take precautions and work together to minimize risks during this critical period.
