What happened

The episode as NWS SGX wrote it up.

Santa Ana winds caused power outages throughout the Inland Empire and foothills of the Santa Ana Mountains. A semi-tractor trailer was toppled over at the intersection of Interstate 15 and State Route 60. Farther south along Interstate 15, blowing tumbleweeds caused traffic hazards. On the Orange County Coastal Plain, a tree fell onto a car in Lake Forest and two large circus type-tents covering Christmas tree lots were destroyed in Laguna Niguel and Mission Viejo.
