After restoring power to all customers Thursday, SDG&E then de-energized 6,909 customers in rural east and north county as a precaution amid high winds and low humidity, with 67,743 at risk of a public safety power shutoff if conditions worsen.

After restoring electricity on Thursday afternoon to all customers in rural areas impacted by public safety shutoffs, strong Santa Ana winds overnight forced San Diego Gas & Electric to turn off the power again.

San Diego Gas & Electric (SDG&E) initiated additional Public Safety Power Shutoffs (PSPS) late Thursday into early Friday in response to the return of strong Santa Ana winds

Utility officials say shutoffs are a necessary, last-resort measure to help prevent devastating wildfires, but they don’t come without impacts to residents, schools and businesses.

A Red Flag Warning went into effect at 4 a.m. Wednesday for portions of San Diego County as Santa Ana winds began to peak.

Over 7,000 San Diego Gas & Electric customers were reported to have their power shut off Wednesday morning as the region remains under a Red Flag Warning due to Santa Ana winds.

According to the National Weather Service, "a Red Flag Warning means warm temperatures, very low humidity, and stronger winds are expected to combine to produce an increased risk of fire danger." CAL FIRE San Diego said they've sent more than 80 firefighters of their own up to Los Angeles to help combat the wildfires,

ABC 10News reporter Adam Campos was live from Ramona to take a closer look at SDG&E's power shutoffs as more than 64,000 customers could be impacted Wednesday in anticipation of Santa Ana wind conditions.

Staff at senior care facilities in Ramona and the rest of East County are preparing for the possibility of power shutoffs with the strong Santa Ana winds and the potential fire risk.
