A wind advisory is highlighting a sharp shift in San Diego County weather, with warm, dry and gusty conditions expected after a period of rain and storms. Santa Ana winds are forecast to affect the region from Thursday through Saturday, raising concerns about power outages, falling trees, blowing dust, difficult driving conditions and rapidly spreading wildfires.

The National Weather Service has issued a high wind warning for inland, mountain and foothill communities. Coastal areas will also face elevated temperatures, with a heat advisory and heat warning in effect for some communities. Highs along the coast could reach the mid-90s.

Critical Wind Advisory Brings Dangerous Gusts

According to forecasters, the strongest winds are expected Friday, although gusty conditions may begin Thursday morning and continue into Saturday evening. Some inland areas could experience lingering winds into Saturday night.

Eastern valley communities may see northeast to east winds of 20 to 30 mph, with gusts reaching 45 to 55 mph. Localized gusts could be stronger near mountain foothills. Western valleys are expected to experience more isolated gusts of 35 to 45 mph.

Mountain communities face the most powerful conditions. Winds in those areas may reach 25 to 35 mph, with gusts of 50 to 65 mph. Forecasters warned that stronger gusts could occur near exposed ridges and foothill locations.

Why Santa Ana Winds Increase Fire Risk

Santa Ana winds typically bring air from the interior toward the coast. As the air moves downhill, it becomes warmer and drier, lowering humidity across the region. Those conditions can dry vegetation quickly and allow a small ignition to spread rapidly.

The latest weather pattern arrives after rainfall from post-Tropical Cyclone Rachel. San Diego Gas & Electric said the recent rain has helped reduce some wildfire risk, but officials continue to monitor conditions closely. No Public Safety Power Shut-Off warnings had been issued as of the latest update.

Residents should remain alert for changing fire weather conditions, especially in areas where dry vegetation, strong winds and low humidity overlap. Activities that could create sparks, including yard equipment use, dragging trailer chains and improperly discarded cigarettes, should be avoided.

Power Outages and Driving Hazards Possible

The high wind warning could lead to downed power lines, damaged trees and scattered outages. Blowing dust may also reduce visibility, particularly in open areas and along roadways. High-profile vehicles, including trucks, vans and vehicles towing trailers, may be difficult to control during peak gusts.

Drivers should reduce speed, keep both hands on the wheel and allow extra space around larger vehicles. Anyone who encounters a downed power line should stay far away and report it to authorities. A fallen line may remain energized even when there is no visible spark.

Essential Steps to Prepare Before the Winds Arrive

San Diego County officials urged residents to prepare before conditions deteriorate. Recommended steps include:

• Secure patio furniture, umbrellas, trash bins, decorations and other loose outdoor items.
• Charge phones, flashlights, backup batteries and necessary medical devices.
• Keep an emergency kit ready in case of extended outages or evacuations.
• Avoid driving high-profile vehicles during the strongest wind periods when possible.
• Monitor official weather alerts and emergency updates.
• Remove or safely store items that could become airborne debris.
• Avoid outdoor activities that could accidentally spark a wildfire.

Officials also encouraged residents to stay hydrated and limit strenuous outdoor activity during the heat. Loose clothing, air-conditioned spaces and frequent water breaks can help reduce the risk of heat-related illness. Children, older adults and pets should never be left inside parked vehicles.

Cool Zones Offer Relief From San Diego Heat

San Diego County’s Cool Zones will provide air-conditioned spaces for people seeking relief from the heat. The network includes dozens of libraries and community centers throughout the county. Residents without reliable air conditioning, as well as people especially vulnerable to high temperatures, are encouraged to identify a nearby location before the hottest conditions arrive.

Once Santa Ana conditions weaken, another weather system could move toward the region. NBC 7 meteorologist Sheena Parveen said a West Coast storm may bring showers and, at minimum, cooler temperatures by the middle of next week. Until then, residents should treat the wind advisory and heat alerts seriously.
