Southern California is bracing for continued strong winds through Sunday, with conditions posing a threat to travel, infrastructure, and wildfire risk. The National Weather Service (NWS) has issued numerous advisories and warnings as powerful Santa Ana winds sweep across the region, bringing gusts that could reach up to 70 miles per hour in mountainous areas. These winds, combined with rising temperatures, are creating a volatile situation, particularly as the region heads into peak wildfire season.
The intense weather system, characterized by high-pressure building over the Great Basin, is driving hot, dry air westward, creating the conditions for these strong, gusty winds. The Santa Ana winds are a recurring phenomenon in Southern California, typically occurring in the fall and winter months, but this event is notable for its intensity and the unseasonably warm temperatures accompanying it. The combination of strong winds and high temperatures significantly increases the risk of rapid fire spread, prompting heightened preparedness from fire agencies.
Wind Advisories and Warnings in Effect
As of Sunday, March 8, 2026, a Wind Advisory remains in effect for much of Los Angeles and Ventura counties, according to the National Weather Service. The NWS San Diego office reports peak gusts of 35-50 mph are expected in valley locations, with even stronger gusts of up to 55-65 mph along coastal slopes. The winds are turning easterly, increasing the potential for higher gusts in the Riverside and San Diego county mountains. These conditions are expected to subside somewhat later Sunday, but remain a concern.
The strongest winds are anticipated in the San Gabriel and Santa Susana Mountains, where gusts could reach 60 to 70 mph. The Highway 14 corridor is particularly vulnerable, and residents in these areas are urged to take precautions. While high-wind warnings expired Saturday afternoon, widespread wind advisories remain in place, warning of downed trees, powerlines, and potential power outages. The NWS forecasts gusts ranging from 35 to 50 mph on Sunday, though lower than Saturday’s peak, still posing a significant hazard.
Rising Temperatures and Fire Weather Concerns
Adding to the challenge, temperatures are significantly above normal for this time of year. The NWS forecasts highs of 79 to 85 degrees Fahrenheit in coastal areas, 82 to 92 degrees in valleys and inland Orange County, 70 to 75 degrees in the high desert, and 84 to 90 degrees in the low desert. Even the mountains, typically cooler, will see temperatures between 57 and 66 degrees Fahrenheit between 4000 and 7000 feet. These elevated temperatures, combined with the dry Santa Ana winds, create critical fire weather conditions.
The Los Angeles County Fire Department is on high alert, preparing for potential wildfires. The dry vegetation, coupled with the strong winds, means that even a small spark could quickly escalate into a large-scale blaze. Fire officials are urging residents to be extremely cautious with anything that could ignite a fire, including outdoor equipment and discarded cigarettes. Red Flag Warnings, indicating critical fire weather conditions, may be issued if conditions worsen.
Impact on the Los Angeles Marathon
The strong winds and rising temperatures are also impacting the Los Angeles Marathon, scheduled for Sunday. Organizers are monitoring the conditions closely and are prepared to make adjustments if necessary to ensure the safety of participants. The National Weather Service indicates temperatures could peak around 90 degrees Fahrenheit by the end of the event, posing a risk of heat exhaustion and dehydration for runners. The forecast for Santa Ana shows a high of 91 degrees Fahrenheit on Sunday, with mostly sunny conditions.
Marathon officials are advising runners to stay hydrated, wear light-colored clothing, and pace themselves appropriately. Medical personnel will be stationed along the course to provide assistance to runners in need. The race route may be adjusted or even postponed if conditions become too dangerous.
Recent Fire Activity
The dangerous conditions already contributed to several small fires breaking out across Southern California on Saturday. One notable incident occurred at a three-story home in the 8500 block of W. Oak Ct. In the Hollywood Hills. According to the Los Angeles Fire Department, more than 100 firefighters responded to the blaze and extinguished it in less than two hours, with no injuries reported. The fire department attributed the rapid spread of the fire to the strong winds. The Los Angeles Times reported on the incident, highlighting the increased fire risk due to the Santa Ana winds.
Other smaller brush fires were quickly contained by responding firefighters, but the incidents serve as a stark reminder of the potential for wildfires in the current conditions. Fire agencies are urging residents to clear brush and vegetation from around their homes and to create defensible space to help protect their properties.
Safety Precautions and Resources
Residents in affected areas are advised to take the following precautions:
- Secure outdoor objects that could be blown away by the wind.
- Avoid travel if possible, especially in mountainous areas.
- Be aware of falling trees and powerlines.
- If you experience a power outage, report it to your utility company.
- Stay informed about the latest weather updates from the National Weather Service.
- Follow fire safety guidelines and be prepared to evacuate if necessary.
