Fire danger is expected to increase in San Diego County this week due to another round of Santa Ana winds, according to the National Weather Service. As a result, San Diego County’s far East County residents may have their power shut-off as early as Wednesday morning. San Diego Gas & Electric (SDG&E) has alerted 24,700 customers in the area that they may have to shut-off power to reduce wildfire risk. The agency has said that there will be no anticipated impacts to polling or ballot counting locations for Tuesday, Election Day. SDG&E has begun notifying customers who are most at risk of a power shut-off via phone, text messages and email. If you were contacted, be prepared to be without power through Friday, the agency said. If a power shut-off occurs, crews plan to restore power as quickly as safety allows. State regulators have approved these Public Safety Power Shutoffs (PSPS) as an important last-minute safety tool to reduce fire risk during dangerous weather conditions, according to SDG&E. The dry, offshore winds will build throughout the day and peak Wednesday evening through Thursday morning. San Diego valleys will see gusts of 35 to 40 mph, with the strongest gusts in the eastern valleys. San Diego’s mountains and some inland valley locations could see gusts of close to 50mph, NBC 7 Meteorologist Brooke Martell said. The NWS has issued Red Flag Warnings for inland and coastal San Diego County and Orange County valleys and mountains through Friday morning. Expect moderate strength Santa Ana winds to arrive Tuesday night through Thursday evening. Relative humidity will get down below 15% in some places and fuel moisture levels are critically low, despite getting the little rain last weekend. All of those factors will combine for severe fire danger, Martell said. The Red Flag Warning is expected from 3 p.m. Wednesday to 7 p.m. Thursday for the inland valleys. A Red Flag Warning is also in effect for our mountains including Palomar Mountain from 3 p.m. Wednesday until 11 a.m. Friday. Winds will gradually weaken Thursday afternoon into Friday with lingering gusts of 35 to 45 mph possible Thursday night into Friday morning for our mountains, the NWS said.
