Southern California Under Red Flag Warning as 5% Humidity and Santa Ana Winds Create Extreme Fire Danger
LOS ANGELES, CALIFORNIA — The National Weather Service in Los Angeles/Oxnard has extended a Red Flag Warning through 6 p.m. PDT Wednesday, October 29, 2025, as Santa Ana winds and very low humidity levels create dangerous wildfire conditions across parts of Southern California.
Critical Fire Conditions Across Los Angeles and Ventura Counties
Forecasters warn that northeast winds of 15–25 mph with gusts up to 40 mph, combined with humidity values as low as 5–10%, will fuel a high risk of wildfire ignition and rapid spread through Wednesday evening. The warning includes the western San Gabriel Mountains, Santa Susana Mountains, and southeastern Ventura County valleys, where dry brush and gusty winds create explosive potential for fire growth. Officials say the strongest winds will persist through Wednesday morning, followed by poor humidity recovery overnight.
Officials Urge Residents to Stay Alert and Ready to Evacuate
“These conditions will favor rapid fire growth and long-range spotting if any ignition occurs,” the National Weather Service said in its alert. Residents living near wildland and canyon areas are urged to prepare for possible evacuations and avoid any outdoor activities that could produce sparks. The agency also advises against using power tools near dry vegetation, discarding cigarettes, or burning debris outdoors. Even small embers could quickly grow into large wildfires under the current weather pattern.
Fire Crews on High Alert Across High-Risk Zones
Local fire departments have increased staffing and patrols across vulnerable areas, including Highway 14 corridors and Ventura Freeway foothills, where past fires have spread rapidly during similar wind events. Firefighters are also pre-positioned in strategic locations to respond to potential ignitions. Officials remind residents that Red Flag Warnings are issued only when a combination of strong winds, extreme dryness, and low humidity could lead to uncontrollable wildfire behavior.
Weather Outlook and Safety Precautions
Meteorologists say Santa Ana winds are expected to weaken slightly overnight but will remain strong enough to sustain dangerous conditions until early Thursday. The public is urged to monitor local alerts, avoid driving or parking in dry grassy areas, and immediately report any signs of smoke or fire to authorities.
