Santa Ana conditions are expected to hit San Diego County, bringing hotter temperatures, low humidity and strong gusty winds Thursday through Saturday.
The National Weather Service has issued a high wind warning for inland, mountain and foothill areas in San Diego County, along with a heat advisory for coastal areas, starting Thursday.

The NWS expects the worst of the winds to occur Friday.
High winds may cause power outages, blowing dust, tree damage and dangerous driving conditions for high-profile, taller vehicles. The high winds warning begins Thursday morning and ends Saturday evening, and forecasters say gusty conditions could continue in inland areas into Saturday night.
How to prepare for high winds
San Diego County officials officials to urge caution and preparation amid the weather conditions that have the potential to down powerlines and rapidly spread wildfires.
County officials offered the following tips to prepare for the weather event:
Secure outdoor items such as patio furniture, umbrellas, trash bins and decorations.
Avoid driving high-profile vehicles during peak wind periods, if possible.
Watch for downed power lines. Stay far back and report them to authorities.
Keep a kit ready with essentials in case of evacuations or extended outages.
Charge phones, flashlights and medical devices ahead of time.
Monitor weather alerts and emergency updates through AlertSanDiego.org.
Stay alert for Red Flag conditions, which increase wildfire risk during hot, dry and windy weather.
Avoid activities that could spark fires, including yard equipment use, dragging trailer chains or improper disposal of cigarettes.
The county advises wearing loose clothing, drinking plenty of water, staying in air conditioned spaces if possible and never leaving children, the elderly or pets in vehicles.
San Diego County has Cool Zones, including 33 branch libraries and community centers, which offer air-conditioned spaces where people can escape the heat. They can be found at the county website.
San Diego Gas & Electric, which monitors weather patterns to determine if power shut-off should be initiated to prevent wildfires, said last weekend’s rainfall from post-Tropical Cyclone Rachel has helped mitigate some wildfire risk.
No Public Safety Power Shut-Off warnings have been initiated.
Another possible storm
Once Santa Ana conditions diminish, a storm system could move back into San Diego County.
NBC 7 Meteorologist Sheena Parveen said a west coast storm, with the potential to bring showers, will at minimum cool temperatures down by mid-week.
