Southern California Santa Ana Winds Peak Across Los Angeles, San Bernardino, Riverside, and San Diego Counties, Triggering Hazardous Travel and Fire Weather Concerns
Southern California — Strong Santa Ana winds intensified across Los Angeles, San Bernardino, Riverside, and San Diego counties on Monday, peaking during the afternoon hours before remaining gusty through Tuesday afternoon, according to the latest wind gust forecasts and real-time observations. The strongest impacts are focused in mountain foothills, desert slopes, and wind-prone corridors, including the heavily traveled I-15 through the Cajon Pass.
Where the Strongest Santa Ana Winds Are Occurring
Forecast maps show peak wind gusts ranging from 40 to 50 mph across San Bernardino County foothills, Beaumont, Banning Pass, Ramona, Julian, and parts of eastern San Diego County. Gusts between 30 and 40 mph are widespread across Inland Empire cities, interior valleys, and select coastal gaps, while coastal areas remain breezy but less intense.
Observed wind gusts as of early morning already confirmed 45–50 mph readings in elevated terrain and mountain-adjacent communities, signaling a strong and well-established Santa Ana event rather than a brief wind surge.
Transportation Impacts and High-Risk Travel Zones
The data highlights Interstate 15 through the Cajon Pass as one of the most vulnerable travel corridors, where crosswinds can become dangerous for high-profile vehicles, trucks, and trailers. Additional concern areas include Highway 79 near Julian, Highway 74, and desert transition zones near Palm Springs and Anza-Borrego.
Drivers are urged to use caution, reduce speed, and remain alert for sudden gusts capable of pushing vehicles out of lanes, especially during peak afternoon hours.
Fire Weather and Power Disruption Concerns
The combination of strong offshore winds, dry air, and low humidity increases fire weather risk across foothills and inland valleys. While no specific fire incidents are shown in the data, conditions are favorable for rapid fire spread if ignitions occur. Additionally, the gusty winds raise the likelihood of downed tree limbs, debris on roadways, and localized power outages.
Timeline: When Conditions Improve
Wind intensity is expected to gradually ease late Tuesday afternoon into the evening, though localized gusts may linger in typical wind-prone locations. Until then, residents in affected counties should secure loose outdoor items and remain prepared for sudden wind surges.
Southern California’s Santa Ana events are a seasonal reality, but this episode stands out for its broad regional coverage and sustained gust strength across multiple counties.
