SAN DIEGO — Thousands of homes are without power on Thanksgiving Day in San Diego County, and a high wind warning is in effect during dangerous fire weather.

Santa Ana winds prompted the high wind warning, which remains in place until noon for San Diego County’s mountains, foothills and inland valleys. A red flag warning is also in effect through 6 p.m. Friday.

More than 5,300 customers throughout the county were without power as of 8:15 a.m. By 4 p.m., that number was down to more than 4,800 customers with outages affecting Alpine, Boulevard, Campo Reservation, Cuyapaipe Reservation, Descanso, Jamul, La Jolla Reservation, Pala, Pauma Reservation, Pauma Valley, Potrero and Viejas Reservation.

Around 11 p.m. Thursday, there were about 5,900 outages with the bulk of them being public safety power shutoffs triggered by unsafe conditions.

Community resource centers are open in three areas:

  • Descanso Community Resource Center, 9545 River Drive, Descanso, 91916. Open from 8 a.m. to 10 p.m.
  • Potrero Community Resource Center, 24550 Highway 94 Potrero, 91963. Open from 8 a.m. to 10 p.m.
  • Valley Center Branch Library, 29200 Cole Grade Rd. Open from noon to 10 p.m.

SDG&E warned earlier this week of outages that could affect up to 43,000 customers with Santa Ana winds in the forecast. That estimate increased to 48,000 Thursday afternoon, according to the Public Safety Power Shutoffs webpage.

Almost 1,000 customers were already without power late Wednesday night “due to unsafe conditions in the area,” the SDG&E outage map said. Two outages affecting a few dozen customers early Thursday were caused by crashes and a third was under investigation.
