An additional 16,432 customers could also potentially see their power shut off.

Strong Santa Ana winds and low humidity will significantly raise the threat of wildfires Wednesday in San Diego County, according to the National Weather Service.

The NWS issued a red flag warning that will be in effect until 6 p.m. Thursday in the county mountains and valleys.

The threat was deemed high, according to the Sana Ana Wildfire Threat Index, which means that "upon ignition, fires will grow very rapidly, will burn intensely, and will be very difficult to control."


San Diego Gas & Electric officials said the utility was considering precautionary power shutoffs for more than 40,000 customers. The shutoffs would be implemented to de-energize power lines in danger of being damaged or downed by strong winds, potentially sparking wildfires.

KPBS has created a public safety coverage policy to guide decisions on what stories we prioritize, as well as whose narratives we need to include to tell complete stories that best serve our audiences. This policy was shaped through months of training with the Poynter Institute and feedback from the community. You can read the full policy here.
