UPDATE (11:58 a.m.) - PG&E officials say power was fully restored at 11:24 a.m.
More than 3,500 PG&E customers were left without power Wednesday morning in an outage that stretches from Shell Beach to parts of San Luis Obispo.
The outage was first reported around 9:38 a.m. on PG&E's website.
The affected area runs south along Hwy 101 on both sides of the freeway, from Los Osos Valley Rd. to Seacliff Dr. in Shell Beach. A portion of See Canyon Road was also left in the dark.
The City of San Luis Obispo said in a tweet the outage is affecting several intersections. Officials urge drivers to treat the intersections as all-way stops and drive carefully.
PG&E officials say the outage was unexpected and appears to have been triggered by enhanced safety settings, which cut power to an area when a wildfire hazard is detected.
Crews must inspect the area and be ready to repair the lines before power can be turned back on.
Right now, power is estimated to be restored by about 4:45 p.m.
A PG&E spokesperson said that some affected areas are outside the high fire threat area and may have power restored earlier.
