San Francisco police issued a shelter-in-place warning late Monday night in San Francisco’s Pacific Heights neighborhood after “some type of problem with a PG&E electrical unit,” according to police.

Emergency officials initially reported a “natural gas issue” in the 3100 block of Pacific Avenue, near Lyon Street, but now are working to repair an electrical issue this morning, police said.

According to a fire dispatcher, a transformer broke and there were also issues with an underground electrical vault in the area, which appeared to have led to a power outage.

As of 12:40 AM Tuesday, PG&E was still working in the area but roads were reopened, according to emergency officials. Police had been assisting with traffic control before roads opened just after midnight.

A PG&E spokeswoman said that utility crews were responding to the area and that an outage was reported in the area at 10:06 p.m. Monday.

The outage was affecting 332 customers in the area as of 11 PM

Another outage was reported at 9:16 PM Mondaym and initially impacted 5,557 customers, spokeswoman Jana Morris said.

That outage was caused by a car crashing into a pole in the 400 block of West Portal Avenue, Morris said.

The number of customer affected was down to 89 as of 11 p.m. and the remaining impacted customers were expected to have service restored by 11:30 p.m.
