SAN FRANCISCO (KRON) — Businesses in downtown San Francisco suffered power outages on Friday morning.

The outage reports started coming in around 8:30 a.m., impacting the city’s Financial District, according to Pacific Gas & Electric.

Crews are working to resolve the issue, which affected about 2,000 customers at the peak of it, the utility said. As of 10:19 a.m., only 31 customers were still impacted.

The power outage is expected to remain overnight, San Francisco police said.

According to PG&E, their response was hindered by underground vaults full of water due to recent storms, forcing crews to pump water to access the equipment.

Traffic guards are on the Embarcadero manually controlling traffic due to street lights being hit by the outage.

The cause is still under investigation.
