Strong Winds Prompt Multiple Wind Advisories Across Southern California

On Friday morning, the National Weather Service (NWS) issued a series of wind advisories across various regions in Southern California, including the Western Antelope Valley Foothills, San Diego County Deserts, and the San Gabriel Mountains. The advisories, which began at different times throughout the day, warn residents to prepare for strong winds that could pose risks to safety and property.

The first advisory was released for the Western Antelope Valley Foothills and Antelope Valley at 5:05 a.m. on March 28, 2025, and is effective from 9 a.m. on Friday until 9 a.m. on Saturday. According to the NWS Los Angeles/Oxnard, residents should expect west winds ranging from 20 to 30 mph, with gusts potentially reaching up to 50 mph. The service cautioned, "Gusty winds will blow around unsecured objects. Tree limbs could be blown down and a few power outages may result." Furthermore, the NWS indicated that these strong winds could make driving hazardous, particularly for high-profile vehicles, urging drivers to use extra caution.

In a related advisory, the NWS San Diego released an updated wind advisory at 9:50 p.m. on March 28, which will remain in effect until 11 a.m. on Saturday, March 29. This advisory covers the San Diego County Deserts and anticipates west winds of 30 to 40 mph, with gusts up to 55 mph. The NWS reiterated similar warnings regarding unsecured objects and potential power outages, stating, "Winds this strong can make driving difficult, especially for high profile vehicles. Use extra caution." This advisory reflects the growing concern over the impact of high winds in the region.

Additionally, the NWS issued advisories for the Western San Gabriel Mountains, Highway 14 Corridor, and various mountain ranges in Santa Barbara and Ventura counties at the same time as the Antelope Valley advisory. This advisory is valid from 2 p.m. Friday until 9 a.m. Saturday, with northwest winds expected to mirror those in the Antelope Valley, again reaching 20 to 30 mph with gusts up to 50 mph. The NWS underscored the dangers of these winds, stating that they could blow around unsecured objects and lead to downed tree limbs and power outages.

Understanding the NWS's alert system is crucial for residents in affected areas. The NWS categorizes wind advisories into three levels: a high wind warning, which indicates that sustained strong winds are currently happening and immediate action is necessary; a wind advisory, which signifies that strong winds are occurring but not severe enough to warrant a warning; and a high wind watch, which warns that sustained strong winds are possible. Each level requires different levels of preparedness and response from the public.

Residents are encouraged to take proactive measures to secure their property before high winds approach. This includes trimming tree branches away from homes and power lines, securing loose gutters and shutters, and identifying safe interior rooms for shelter during severe weather. Those living in mobile homes are advised to seek sturdy buildings for safety during high wind events.

When strong winds occur, the NWS recommends taking shelter immediately in a sturdy building, preferably in an interior room or basement. If caught outside, individuals should seek shelter in their vehicles if no sturdy buildings are nearby. It is crucial to avoid areas where trees or power lines may fall, as downed lines can be live and pose significant dangers.

After the winds subside, residents should remain vigilant. The NWS advises against approaching downed power lines and encourages reporting them to local authorities. Care should also be taken when handling debris that may have blown into yards, as sharp or hazardous materials may be present.

As these wind advisories remain in effect, it’s essential for residents to stay informed and prepared. The NWS continues to monitor conditions and provide updates as necessary, ensuring that communities remain safe during these potentially dangerous weather events.

In summary, the advisories issued by the National Weather Service highlight the importance of taking precautions during high wind events. With strong winds expected across multiple regions, residents must remain alert, secure their properties, and follow safety guidelines to mitigate risks associated with these weather conditions.
